M27

Last night’s weather was “iffy.”  The humidity was high, seeing was little below average, but it was a comfortable 68 degrees.  I tried using Maxim DL for the first time.  I was able to get the DSLR and the guide cam to work, but guiding using this program was still confusing to me.  I decided to figure out and learn the program another night.  Back to running PHD.  This was the second night out using the guiding program.  The process was a lot easier to use the second time.  I did run into some computer errors, mostly due to forgetting to shut down the power shut down mode on my laptop.  I finally was able to get some longer exposures.  Started with 5min exposures, and the longest for tonight was 8min.  I am sure that I could have gotten more than 10min, which I am really impressed about.  Here is the shot of M27 that I did.  I used 4 shots at 5min each, 1 at 8min, and 1 at 2min.  I did 3 sets of 5min, 1 8min, and 1 2min darks.  No bias shots, because I forgot about them.  I stacked the imaged in DSS and did the post processing in Photoshop CS4 using Carboni’s Astronomy Tools Actions Set.
