800mm mirror lens for shooting the moon

8 years 5 months ago #462008 by Glen Martin
Anyone been tempted by picking up one of these cheap mirror lenses?  Like the Samyang 800mm f/8?  For the price kind of tempting, however just wondering what I'll get!  LOL  Shooting the moon is generally between f/8 and f/11 so this in theory should work perfectly?

800mm mirror lens for a few hundred bucks compared to a normal 800mm lens if one existed for $10,000.  Yeah there might be a few things missing from the mirror lens.  LOL

A friend of mine has a 500mm mirror lens and although it has a nice focal reach, the image quality is rubbish IMO

Pass and save your money, these lenses you'll spend more in post trying to get crappy shots turned into good than its worth.  Just my 2 cents.

My brother has one, I think he used it a couple times and that's the last I saw of his.  I want to say his is 600mm.  This was a couple years ago, I need to see what he did with that.

If you are one of those really lucky types then you might get that 1% lens that works well. Other than that forget it. You are better off getting a Catadioptric  telescope with an adapter. Or get a nice used 400mm lens, and then use a TC or crop to taste.
