Revelation ED80

[Merlin66]

Anyone imaging with a Revelation80? I've just picked one up s/h and I'm finding a bit of astigmatism.

Any comments??

I used to own one (i can't remember how it performed, it was a couple of years ago) but i sold it to Ant. He now uses it as his main imaging scope. Maybe worth sending Ant a PM. Or hopefully he'll drop in on this thread.

I do remember that it performed very well visually. I had no complaints.

My one was 'tweaked' by Steve at Telescope House so i'm not sure how it stacks up against an out of the box one, but I thought it was a lovely 'scope, wish I hadn't needed some money and sold it. There was a bit more field curvature than the slower SkyWatcher 80ED, but nothing serious for a small-chip CCD although a DSLR would have needed a flattener of some sort.

I'll set up my star tester and see if I can quantify the problem. Maybe, if I'm lucky, a re-adjustment of the objective elements may be enough!!

Don't have ANY issues with the Genesis or the SW ED80, great scopes, love them.

I reviewed this scope (think it is the same one, it is the one TH described as a 'fluorite doublet - it uses an element of FPL-53 glass) for UKAI, the first scope I was sent had a astigmatic like issue too, it was replaced by TH, and the second one was fine.

The review is here...

Appreciate the honesty in the review!

I'll see how easy/ difficult it is to re-set the objective.

Keep you posted........

Well, first things first, this isn't an ED refractor. None of the "detailed" markings on the objective cell just some words which says its a good lens!

When I looked carefully it's just a glued doublet! Basic as you can get!

I pulled it apart, and found there was NO adjustment in the cell, its just jammed in place and held by the plastic baffle cone. It was VERY tight, but there's not too much you can do about it.

Hmmmmm, something about buyer beware!!!!
