<![CDATA[Set of Three (3) Leveling Feet for Dobsonian Telescopes]]> http://www.opticsmart.com/leveling-feet-for-dobsonian-telescopes.html

Price includes postage in the Continental U.S.!


Getting your Dobsonian Telescope's base level is important when using an object location system like a built-in Setting Circle, or a computerized system like Orion's Intelliscope.  And even if you don't use an object location system, setting your base level will make it more stable and prevent it from rotating in azimuth due to gravity.

These custom leveling feet are made from heavy-duty 8 gauge steel, with 3/4" tall threaded nuts welded to the brackets, for durability and stability.  The leveling bolts have approximately 2 1/2" of travel making it easy to get your base level on rough or sloped terrain.  The comfortable 5-lobe knobs makes adjustment quick and easy, and the large 1.5" diameter feet have a knobby, non-slip rubber insert in the bottom, ensuring that the base will stay where you put it, and won't scratch hardwood floors when stored indoors.

Mounting screws included!

A truly revolutionary product with ground breaking technology, SkyProdigy™ is the product of a culmination of decades of telescope advancements.  It combines electronic motors, an intelligent on-board computer, a digital camera and StarSense™ technology to create an automatic, instant alignment telescope that requires no input from the user.  Simply turn it on, push a button and enjoy the view!  It’s that easy.

 

The SkyProdigy’s automatic alignment process takes only a few minutes, then you will be ready to select from thousands of objects to view.  Not sure what to look at? Select the Sky Tour option; this feature offers a customized list of the best objects in the sky to view for your exact time and location anywhere in the world!

 

No knowledge of the night sky is required.  One touch innovation turns anyone into an instant astronomer!

 

Celestron’s SkyProdigy telescopes use an integrated imaging camera and patented StarSense Technology to automatically align with the night sky and determine where the telescope is currently pointing. The camera automatically captures an image of the sky, which is processed internally to positively identify the stars in the image. Once a positive match is found, SkyProdigy determines the coordinates of the center of the captured image. The process is automatically repeated two more times so that the system has three known alignment points that can be used to make an accurate model of the night sky. From this information the user can select any celestial object in the hand controller’s database, and SkyProdigy will automatically move itself to the correct position.

 

+The SkyProdigy’s internal camera does not have an external output allowing users to view or save the captured images. The captured images are used internally solely for the purpose of self-aligning the SkyProdigy telescope.

<![CDATA[Celestron Oxygen III Narrowband Filter - 1.25 Inch]]> http://www.opticsmart.com/celestron-oxy3-nb-filter-1-25.html

Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the unnatural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

 

The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.

<![CDATA[Celestron UHC/LPR Filter - 1.25 Inch]]> http://www.opticsmart.com/celestron-uhc-lpr-filter-1-25.html

The Celestron 1-1/4" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow).


The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites.

 

In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:

* The multi-layer dielectric coatings are plasma assisted and Ionbeam hardened using the latest technology for durability and resistance to scratching.

* Improved transmission translates to maximum image brightness and contrast. Users of smaller, 4"-11" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact. 

* The high transmission, sharp cutoffs, and more moderate 60nm passband of the UHC/LPR filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader bandpass and inclusion of an extremely efficient H-Alpha passband (656nm).

An Apertura Dobsonian Reflector Telescope is the very definition of "bang for the buck". For the base price you get a high quality telescope with lots of aperture, great features, and a nice complement of accessories (including a Laser Collimator!) And for those who demand the very BEST in performance, convenience, and professional fit-and-finish, you can add our optional Tweaker's Dream Package. Serious astronomy enthusiasts often add these performance tweaks and extra features to their Dobsonian telescopes after purchase in order to make them perform better, move better, and look better. But now you can order your Apertura scope with all the best known tweaks already professionally installed so that you can spend your time doing astronomy and learning about the sky, instead of spending hours on researching methods and materials, tracking down vendors, and getting frustrated with trial-and-error prototyping.

 

Features included in the base package:

2 inch, dual-speed Micro 10:1 Crayford style focuser, with 1.25" adapter

Right Angle Correct Image (RACI) 8x50 finderscope

1.25" 9mm Plössl eyepiece (high-power) with 52 degree field of view

<![CDATA[Set of Two (2) UHMW-PE Secondary Mirror Washers]]> http://www.opticsmart.com/uhmw-pe-secondary-mirror-washers.html

Price includes postage in the Continental U.S.!


For the secondary mirror, the standard back plate for the collimation screws on most Dobsonian telescopes is metal. The collimating screws press against this plate to move it during collimation and to hold it in place. Over time the metal plate is often gouged by the screws, creating divots that hinder the accuracy of collimation. The UHMW-PE Washers sit on top of the metal plate and, with a high resistance to wear-and-tear, prevent these divots ensuring higher accuracy of collimation even after years of use.

<![CDATA[Soft-Grip Guide Knob]]> http://www.opticsmart.com/soft-grip-guide-knob.html

Price includes postage in the Continental U.S.!


Price also includes 'mounting bolt' for installation!

When you use a basic Dobsonian telescope, you generally move it around during viewing by simply pushing or pulling on the main tube. That method works fine, but many experienced astronomers add a nice little knob to their Optical tubes so that they have an easy, comfortable way to guide their telescope around the sky. This Soft-Grip guide knob has a rubberized handle which is much more comfortable on those chilly nights when holding the metal telescope itself isn’t your first choice.

 

Installation instructions:


You will need to drill a 1/4" hole in the side of your Dobsonian's Optical tube. The exact location of the hole is a matter of personal preference, but we generally recommend you drill the hole about 2" from the open end of the tube, and about 1".5" from the seam on the underside of the Optical tube (on the side of the seam closest to you when seated at the eyepiece). Be sure to point the open end of the telescope down towards the ground while drilling the hole to ensure that all metal bits fall out of the scope and not on the mirror. It is also a good idea to remove the grey metal ring from the end of the scope first (by removing 6 phillips head screws) so that metal filings don't get caught under that ring and later fall on the mirror.  Once you've drilled the 1/4" hole, simply feed the included bolt through the hole from inside the Optical tube and then thread the knob onto the bolt and tighten.

The common four-hole accessory tray that comes standard with your AperturaTM Dobsonian Telescopes as well as most Dob scopes is a nice feature for a beginning astronomer. But that standard tray has only one 2” diameter hole and three 1.25” diameter holes, and most astronomers quickly find themselves running out of places to put their growing collection of eyepieces, adapters, collimators, etc. This additional, accessory 5-Hole Eyepiece Tray has THREE 2” diameter holes plus two 1.25” holes. So with the standard tray plus the upgrade tray, you will have plenty of room to store your favorite eyepieces, a collimator, plus a a nice assortment of other accessories while observing.

** Includes three screws for attachment to your telescope base **

Price includes postage in the Continental U.S.!


The secondary mirror of any Dobsonian telescope will occasionally need to be adjusted in a process known as collimation, and our Apertura Dobsonian telescopes come standard with Phillips-head screws for collimating the secondary mirror (as do most Dobsonians by Zhumell, Orion, Meade, Celestron, etc.). The Collimation Thumbscrews eliminate the need for a Phillip’s head screwdriver to collimate the secondary mirror (which means you don’t have to worry about dropping a screwdriver on your beautiful new primary mirror!). These black, fully threaded screws replace the recessed factory screws and extend the grip-point with a 1/2 inch diameter head to allow you to quickly and easily adjust the secondary mirror during collimation. The secondary mirror is suspended on thin metal spider-vanes which can flex under the pressure of a screwdriver, but with these thumbscrew knobs you can use a more precise, lighter touch during alignment, increasing the accuracy of the collimation. Our thumbscrews have metric M4 threads to fit our Apertura scopes, but will also fit many other popular Dobsonian telescopes by Zhumell, Hardin Optical, GSO, Meade and Celestron (but be sure to check your threads with an M4 metric screw before ordering).

Flocked interior – Flocking has been used by astronomers in the know for many years to squeeze every last ounce of performance from their scopes, by soaking up any stray light inside the optical tube that might otherwise spoil the view.  So we apply high quality flocking to the ENTIRE inside surface of the Optical Tube Assembly from end-to-end, in one solid piece, for an incredibly elegant finish that must be seen to be fully appreciated.

 


*NEW* Upgraded primary collimation springs – Your scope's performance depends on accurate collimation (alignment) of the primary mirror.  The primary collimation screws that adjust the mirror's alignment have compression springs that hold it in place, and as part of the Tweaker's Dream Package upgrade, we replace those stock springs with larger and stronger stainless steel springs that will help keep the mirror collimated more accurately and longer.

*NEW* Light Shield – Unwanted stray light can come from many sources including streetlights, houses, and even the moon.  And because the focuser in a newtonian reflector is relatively close to the end of the optical tube, stray light can shine over the top of the OTA and directly into the bottom of the focuser inside the optical tube, which will degrade contrast at the eyepiece.  The NEW light shields included with the Tweaker's Dream Package are the answer!  Quick and easy to put on and take off, these custom designed, laser cut shields are made from ABS plastic and are finished on the inside with the same flocking used to line the optical tube, so these shields do a fantastic job of blocking stray light from opposite the focuser AND absorbing stray light from the front side to prevent it from ruining your contrast.

Hand-adjustable secondary collimation screw knobs – These adjustment screw knobs eliminate the need for a Phillip’s head screwdriver to collimate the secondary mirror (which means you don’t have to worry about dropping a screwdriver on your beautiful new primary mirror!).  These black, fully threaded screws replace the recessed factory screws and extend the grip-point with a 1/2 inch diameter head to allow you to quickly and easily adjust the secondary mirror during collimation.  The secondary mirror is suspended on thin metal spider-vanes which can flex under the pressure of a screwdriver, but with these thumbscrew knobs you can use a more precise, lighter touch during alignment, increasing the accuracy of the collimation.

Upgraded Washers for the secondary mirror – Most standard Dobsonian telescopes (including basic Apertura™ telescopes) come standard with a common metal fender washer between the secondary mirror holder and the collimating screws, and with time and use, it can become difficult to accurately adjust the secondary mirror.  But a couple of years ago, CloudyNights.com forum member Jason D. came up with an incredibly simple yet elegant solution.  He cut a washer out of a Milk Jug (yes, literally from a discarded plastic Milk Jug) and placed the plastic washer between the tips of the collimating screws and the metal fender washer.  That simple tweak made it much easier to rotate the secondary mirror, and made the collimation screws work more smoothly (and later it was decided that two “Milk Jug” washers was even better than one).  Well, we knew that we couldn’t honestly call our upgrade package the “Tweaker’s DreamTM” unless we included this nifty upgrade.  But not wanting to dig through the garbage and cut thousands of washers from old Milk Jugs, we put our thinking caps on.  Standard Milk Jugs are made of High Density Polyethylene (also known as HDPE) and we could easily have washers custom-manufactured from HDPE.  But while “Milk Jug” washers do the job quite well, our experience in manufacturing told us that there was actually an even BETTER choice – Ultra High Molecular Weight Polyethylene (also known as UHMW-PE).  UHMW-PE has higher physical strength and abrasion resistance than HDPE, meaning it will last longer.  And UHMW-PE has a significantly lower coefficient of friction than HDPE, meaning that it is slicker which helps the secondary mirror holder and collimating screws move against each other more easily.  So we took the “Milk Jug washer” idea and made it just a little bit better! Two UHMW washers are pre-installed with each Tweaker’s DreamTM Package.  Oh and by the way, our washers are black and don’t smell like sour milk.  :-)

 UHMW_washers



Soft-grip guide knob – When you use a basic Dobsonian telescope, you generally move it around during viewing by simply pushing or pulling on the main tube.  It works fine, but many experienced astronomers add a nice little knob to their Optical tubes so that they have an easy, comfortable way to guide their telescope around the sky.  So we’ve included a very nice “Soft-Grip” handle that is pre-mounted in the perfect spot on your Apertura™ telescope.  And the rubberized handle is much more comfortable on those chilly nights when holding the metal telescope itself isn’t your first choice.

 

soft-grip-guid-knob


 

Extra 5-hole accessory tray for base – The four-hole accessory tray that comes standard with most Dobsonian telescopes is a nice feature for a beginning astronomer.  But the standard tray has only one 2” diameter hole and three 1.25” diameter holes, and most astronomers quickly find themselves running out of places to put their growing collection of eyepieces, adapters, collimators, etc.  The Tweaker’s DreamTM Package includes an additional accessory tray that has THREE 2” diameter holes plus two 1.25” holes.  So with the standard tray plus the extra tray included with the Tweaker’s DreamTM Package, you will have plenty of room to store your favorite eyepieces, a collimator, plus a handful of other accessories while observing.

Please read John Kramer's Professional Review of the Apertura AD12 Dobsonian Telescope 

and be sure to check out his VIDEO REVIEW on Youtube.

 

An Apertura Dobsonian Reflector Telescope is the very definition of "bang for the buck". For the base price you get a high quality telescope with lots of aperture, great features, and a nice complement of accessories (including a Laser Collimator!)  And for those who demand the very BEST in performance, convenience, and professional fit-and-finish, the Tweaker's Dream Package is included with every Apertura AD12, featuring a fully flocked Optical Tube for maximum contrast at the eyepiece, Collimation Screws and Collimation Washers, a Control Knob and an additional 5-hold Eyepiece Tray (see below for full description and photos). Serious astronomy enthusiasts often add these performance tweaks and extra features to their Dobsonian telescopes after purchase in order to make them perform better, move better, and look better. But now your Apertura scope comes with all the best known tweaks already professionally installed so that you can spend your time doing astronomy and learning about the sky, instead of spending hours on researching methods and materials, tracking down vendors, and getting frustrated with trial-and-error prototyping.

<![CDATA[Telrad Reflex Finder with Mounting Base]]> http://www.opticsmart.com/telrad-reflex-finder-with-mounting-base.html

The Telrad sight is a non-magnifying sight to make star-hopping fun and easy. After a simple alignment process to ensure that it is perfectly lined up with your telescope and finderscope, the Telrad's intuitive "heads-up-display" of a lighted red reticle allows you to simply look through the glass window to see what the telescope is looking at.When you point the Telrad at any object in the night sky (for example, a prominent star like Polaris or Vega) you know the telescope's eyepiece will be centered on that same object.

 

Then as you explore the sky you can use the Telrad to help you find fainter Deep Sky Objects by referring to star charts that include the Telrad reticle printed to scale. The outer circle in the lighted red reticle covers 4 degrees of the sky, the middle circle covers 2 degrees, and the small inner circle covers 1/2 degree. And the built-in variable switch allows you to easily reduce the brightness of the projected reticle when looking at fainter stars or increase brightness for brighter objects.

 

Requires 2 AA batteries (not included).
