one is concave the other convex, both hyperbolic.....nice music at the end...and the beginning...the poor kid was just relaxing when you got up...flash gordon at the end photobombing the video....
@@AVAstronomy Yes, but in this video (which is, of course, 2 years old, and shot before you had gathered any light) you mentioned getting a reducer. Thanks for the reply. Do you use this scope? Do you like it? Is it too big a step for a novice from a 102 mm refractor with 500 mm f.l.? I like the red iOptron, because red is faster.
@@ronstewtsaw Hi Ron, yes I have used the scope without a reducer and have Achieved really nice results with it. Most of my galaxy images and nebulous are on my Astrobin. This scope by design does not need a focal reducer or field flattener. Having said that, there are some focal reducers for refractors that can be used with this 8 inch RC scope. I just never got around to using them. I would not recommend this scope for a novice as they are very challenging to collimate and have a very slow focal ratio. Personally, if I had to do it all over again I would recommend an 8 inch Celestron Edge HD scope with a reducer instead. They are a bit easier to collimate and have a faster F ratio with A similar focal length. As long as your mount can handle the weight and you feel confident about your experience imaging then I’d say go for it otherwise maybe hold off.
@@AVAstronomy Most excellent. Thank you. Those EdgeHD scopes really do seem to be the sweet spot. Plus you can attach a Hyperstar and have a whole different type of scope.
Hi. I am planning to get the same OTA. I am concerned about collimation. I have had issues collimating my SCT’s 11 and 8. My question is how easy it is for this scope to go off collimation?
To be honest it's a great scope but collimation is no walk in the park. It's time consuming and can be frustrating. however, there are good videos on how to to do this (including mine) but Allen Mitchell has an excellent video as well should you decide to go with an RC. I've gotten some great images from it but it's collimation takes time and patience
Covered all the points. Great review!

I'd think you'd need a special reducer to maintain the flat field.
Actually has a very nice flat field without a reducer.

what is the music score?
I want one
Christopher Cyr go for it. It’s a great scope!
