A mounting cradle-ring clamps over optical tube assembly (OTA). The cradle-ring assembly allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle. Its two-speed rack-and-pinion focuser helps make fine-focusing fast and precise. A 90° star diagonal is also included for more comfortable viewing. The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.

Quality optics at a good price.

By Frank

I have had this scope for a few weeks now and the optics are great. I do some visual but usually I do astrophotography using ASI AIR PLUS and a ZWO ASI 183MC camera. The images I get are great and stars are tack sharp with no color bloating or fringing. Files are FITS files and as soon as I figure out how to use a good photo processing program my photos will look better. Only wish the focusing tube was longer so I dont need to ad so many adapters extensions to reach focus, But everyone go's thru that issue.Scope works great with a DSLR also. I am glad I bought it and B&H delivered fast and well packaged.

A well built and designed instrument

This a fine instrument, well constructed and has excellent optics. I have been very impressed with its performance. It is light and easy to handle. The focuser works smoothly and with precision. I am extremely pleased with this instrument.

Great deal!

This was a wonderful price for a piece of hardware with this spec. It will take some time to identify just how good it really is. Out of the gate I am getting some vignetting with my APSC DSLR. I am surprised how much customization is needed in order to pursue Astrophotography with this scope. One of the more shocking things is that the 'handle' on the top doesn't have a practical way to mount to it, and the guide/spotting scope bracket is non-standard. Generally speaking it is well made, lightweight and easy to use. Definitely recommended.

B&H Needs to work on QA

I just received the replacement order to find it also pack poorly and damaged. I think B&H keeps recycling the same returned equipment over and over without ever looking in the box. I hope it works because i can't deal with B&H again.

question

What do I need to purchase along with this product to connect my Canon 60D for astrophotography ?
Asked by: Bader A.
First you would need a T-Adapter that goes into the eyepiece part of the scope. The Celestron-SLR (35mm OR Digital) Camera Adapter would work great. Wesbite Link to the T-Adapter: <a href= http://bhpho.to/1lwAhIO target= _blank >http://bhpho.to/1lwAhIO</a>Now to mount your Canon 60D you would need what is called a T-Ring, which threads onto the T-Adapter. The Vello Lens Mount Adapter-T-Mount Lens to Canon EOS Camera will be perfect. Website link to the T-Ring: <a href= http://bhpho.to/19wYgWY target= _blank >http://bhpho.to/19wYgWY</a>These are the 2 adapters you would need to attach your camera to this scope.
