As the topic states, last night was one of those nights.
First of all I consider myself an absolute beginner. I've been deep sky imaging for about 4 years off and on. the off is when I have equipment problems. The last equipment problem was the power panel for my LX200gps which took over a year to get due to supply problems. So being that I'm getting older and forgetful I have to relearn everything.
I'm currently working on imaging NGC 2359, Thor's Helmet. my first set of data was 27x600s subs. Thor's Helmet is very dim; so I didn't think I had enough data. I decided to try taking 1200s subs last night. Since it doesn't rise high enough for imaging until around 12am local, I started at 11:30pm. I start by getting close and plate solve using AstroTortilla. I noticed that my 30s subs for plate solving weren't working. the stars were to dim. Since I was low in the sky I just figured it was the sky glow from Tucson and waited a while to try again. Still did not work. I decided to raise the scope a little and try again. after 2 more try's it worked and I got synced up. I align on the target setup MaximDL to get the subs. I go to set up guiding using the off-axis guider with my SBIG STi camera. Normally I use 2-3 second subs to guide with; but I couldn't find a good guide star. This worked the previous night with just 2 second subs. I wondering what is wrong. Am I that forgetful that I missed something or did something wrong. I try 4 second subs and still no good guide star. Am I in the wrong location? I compared a 60s sub of the imaging camera and a sub from the previous night. I have the right alignment.
I decide to use 2xBin on the guide camera and try again. I find a good guide star. I start guiding at 3s subs. That lasted about 15 seconds and Maxim lost the guide star.; so I go to 4s subs and try again. Great it's not losing the guide star. I wait around 5 minutes, it's still guiding. Great! I start the 1200s acquisition. 8 minutes in it loses the guide star. Now I have to start over. I go to 5s subs for guiding and start again. Great everything is working! Not. 12 minutes in the guide star is lost. It starts going in and out. It's now 2am and I give up.
Seeing and transparency were supposed to be 4/5 I would put them at both at around a low 2/5. I watched the guide star fade in and out for around 10 minutes before deciding to pack up and go to bed. Chock it up to a bad night. Lets hear your bad night stories.
