More learnings...

By default Neb2 debayers the fits before saving it. This makes the fits files 3 times bigger. This is definitely a problem. I do not know how this affects the calibration, alignment and stacking in DSS!! Anyways, I gave another go at grabbing the data of NGC2237 (Rosette nebula) with Neb2 saving the data as raw files instead. And here's the result:


Overall I am very happy. But a few things I need to correct next time around. This data acquisition was originally 48 frames of 4 minutes each. But I could only use 35 frames since the focus shifted pretty severely during the run. and beyond the 35th frame it was completely out of focus. I need to setup focusmax optimally and try and use the temp. compensation feature. Calibration frames were 60 Flats and a master bias breated out of 60 Bias frames. Also, although the IDAS LPS is helping a lot, there is still a lot of light pollution gradients in my image and I have an Astronomik UHC on order. Hopefully that will help. We will see in a few days...
