I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
Quote:So if your reference frame is 0, then the next one may need to be rotated .02 degrees, the one after that .04 degrees, the one after that got blurred so it was tossed out, the next one is .08, the one after that had to be tossed, the next is .12, and so on.To say it is tedious is an understatement. And this has to be corrected before you can give them to an image stacker capable of auto-alignment.

Quote:Well, yeah, but you can't take longer exposures in alt-az. That's why it's rotational heck. I have seen a lot of software claim it could do rotation automatically. I've never seen anything resembling a successfully rotated stack run in front of me. Auto-align, yes. Rotate- not even close. -Rich
