Been using AIP4WIN for a month and a half, the tutorials and the reduction excel sheet, that everyone's so graciously provided here....Thank you for your hard work.
Got some questions, hope this is the right place to post, first time posting for me. Gotta admit, I'm a lil frustrated trying to get the "numbers" where they need to be.
I'm also using a Nikon D40, 15 / 4 sec exposures, same for darks. I've tried 55mm and 80m and get the same results. I'm only shooting / using one set of exposures, instead of 3 or 4 sets that I notice others are using (perhaps my problem?). I haven't done any variables yet, just experimenting on known stars as my targets, IE...Mu Leo, Del Uma, and Mu Gem.
My issue is after reduction, I'm about +.06 to +.2 off from the target stars and check stars. I actually was dead on with my check star with Mu Gem (I used Eps Gem for the check star), but here, Mu Gem (target) was +.222 off. Grrr.
I think using Del Uma was a bad idea, due to the fact some of the comparison stars are over 5 degrees away. Might be running into air mass issues. But, as with Del Uma, my results seem to be about the same.
Was wondering if others happened to run into the same thing when starting out and if it there was an obvious solution. I know it's hard to troubleshoot this with the lil info I've given. Seems like I'm so close.
And....does anyone else have some frustration using AIP4WIN? Seems like a very NON-intuitive program. I'm trying to work thru it since I paid ~ $100 for it. The book is great tho.
Anyways, any suggestions would be greatly appreciated. Thank you for your time.
