Quote:About the coma, a Google search showed that some people said there was coma around the edge, but it was very little during visual use without a coma corrector. Even if they are wrong and it is bad, wouldn't a coma corrector or barlow lens fix that? I'd eventually have to get a coma corrector for photography anyway
Quote:Quote:I think the AVX will have trouble with a 17 pound 8" newt... A 6" would be better. I don't think a 8 or 10 " newt would require a CGEM, Atlas, or iOptron 45Curious POV since my neighbor has his 22# 9.25 HD Edge on his AVX and it works great and he takes amazing pictures through it. If the AVX can perform decent AP with a 22# OTA a 17# newt should be a walk in the park. An 8" Newt will be fine on ether an AVX or the CGEM... moving to a 10" newt I would move to the Atlas or CGEM if for no other reason then for windy nights... 10" newts make for a large sail.

Quote:The meade mounts I have owned in the past were always ok as long as luck was with you. I never had complete confidence in them. Goto's would be accurate one night and a disaster the next. I bought a orion atlas 2 years ago and what a upgrade. From the first night I used it, it has been dead on every night. Nothing magical, just set it up , align and use it. I use everything from a 8 lb to a 55lb scope on it and it just works all night with no issues. If you want a no nonsense mount that works, buy an atlas.

…Missing my RV-6. Why oh why did I sell it?!?!?!?
Quote:I suppose an advantage of the long focal length of a SCT is that long focal length eyepieces can be used to give a larger viewing area for a given magnification and field of view. That way a person won't have to get so close to the eyepiece and squint to see small objects in the sky.
Too much astronomy junk, the CFO is getting irritated.

Quote: That reducer is not cheap and only covers an 18mm circle (e.g. Micro-4/3 camera or 8300 chip camera) but it's one approach..

Quote:Just so you know Meade has stopped making the LX80 so any that a retailer may have is old stock. If you want the $799.00 LX80 and use it with a lighter OTA you may still find a vendor somewhere with one in the back room. Otherwise wait until the new version is released.

We are all debating a mount that is basically "done"?
