Quote:I had posted several pictures during the July 20th week of similar shots. I think i was getting some excellant shots then. Wish the mount had not fallen, but it did. And apparently, that ruined everything.But the point i want to make is this. With proper polar alignment, and with a 10 lb OTA, i was getting images like this (60 and 120 sec) and have the data on 13 targets to back it up. That was UNGUIDED.
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:Sorry Andrew. I must STRONGLY disagree with your comments above.
Quote:I have got to say that this "all star polar alignment"(ASPA) on my CGEM DX is the greatest thing. No more drift or iterative for me. Too bad Meade doesn't have it. Mike if you do PHD guiding you don't have to get the polar alignment perfect, just close. In another group one guy said its better to be off a little, then you select north or south instead of auto in the Dec guiding (last box in the graph). Others were disagreeing with him. I tried it a couple days ago and it works so much better than trying to get the polar alignment perfect. Your actually forcing it to guide Dec in one direction only instead of back and forth. For years, I had always tried to get the polar align. perfect then use auto. This other way is alot easier. But if you do unguided polar has got to be perfect. You might already know this stuff but it was new to me.neilson

Quote:Here the file for my last try at PHD. Looks about the same to me as the previous ones.
Quote:The newest Audiostar firmware has changed the way it works, so it may work better than before, but it will still have no "processing" advantage over std serial pulse guiding, as in the Audiostars, serial and ST4 end up doing EXACTLY the same thing.
Quote:I wonder if the LX80's true calling might be as a random number generator.
Quote: Hopefully they're still working on it.
Quote: Andrew. But this is still with the old firmware, isn't it?
Quote:Wait- the new firmware does this?
Quote: So which is better, the previous or the new?
Quote:I was thinking this was the old version and the one would be clean.
Quote:So in the meantime, did you see the eclipse?
Quote:What you're describing just sounds like this has all gotten away from them.
