🌠 See More, Capture More — Expand Your Universe with Every Frame!
The Celestron .7x Reducer Lens for EdgeHD 800 telescopes increases the field of view by 43%, features fully multi-coated optics for enhanced brightness and contrast, and uses a precision 5-element design with 105mm back focus to ensure sharp, high-quality astrophotography. Lightweight at 0.8 lbs, it reduces exposure times and improves image scale, making it ideal for capturing faint deep-sky objects.

Must have accessory for a versatile telescope.
The reducer is well made. It is also large and heavy. The Edge 8 HD scope is already "tail heavy". So, monitor eypiece/diagonal clearance when using an alt-az style mount.

The sun fits entirely in the camera's view
The Celestron 8" CPC telescope is unable to view the entire disk of the sun, so the focal reducer is required. Now both the sun and moon fit entirely in the camera's view.

Beautiful hunk of aluminium and glass
I can only comment on build quality, as it has been raining since I received it. As all amateur astronomers know, as soon as you acquire a new piece of gear, you must endure your "Rain Punishment". That being said, this is a superbly manufactured instrument. Fit and finish are flawless. The claims are that with this reducer, you can essentially cut your exposure time in half, which is really important to me because my polar alignment skills are really lacking, and my auto guiding setup doesn't work(yet). I'm getting much better, and have even managed to get some 2 minute exposures a few times. The trouble with that is at 2 minutes, my camera develops a lot of heat and "noise". The concept of capturing the same amount of photons in half the time is very appealing, and by all accounts this focal reducer accomplishes this admirably.

Pricey but an important lens.
Makes collecting photons a speedier process. Sure wish it was cheaper!

More than a Nice-to-Have for Astrophotography
For someone doing astrophotography, after a camera and a guiding solution, this is the next accessory to get. I haven't tried this with my full frame DSLR, but I use it regularly with my CCD cameras. I also have a Hyperstar, but that is too short except for very wide objects (like M42 or Andromeda). For everything else it is either this or prime focus. In fact, because I have a DSLR, which itself has such a wide field of view, I will probably sell the Hyperstar and stay with the option of the focal reducer (f/7), prime focus (f/10) or the Televue 2.5x Powermate (f/25).

Having to return this a year later. Comets in ...
Having to return this a year later. Comets in the edge of the photo means no flat field. Buy are your own risk.

Works good. Does what its supposed to well. One small complaint
It works and does what its supposed to do and does it well. The only complaint amd reason I gave it 4 stars is the lens is almost flush to where the mount screw are. This just begs for you to bump, touch, or hit it witb whatever your tying to attach to it. In terms of quality and functionality though I would give it 5 stars.
