Description

This is my first ever mosaic and it comprises of two panels of 20 subs each, at 12 minutes, 720 seconds, long exposure time. The integration length was a total of 8 hours. What was surprising was that on the second night for the top section, the data was worse, which I am sure was partly to do with the nearly full moon that really was quite close to the object. This meant that I was unable to stretch the image as far as I could have done because the top section's data would not have handled it, and would have become distorted in the process. [If one looks at the previous bottom section of this object that I took, they will see that the fainter nebulosity is more noticeable compared to this one, for this very reason]. Either way, I am very happy with the result. I used my 3" triplet for this and the Atik 460EX monochrome. Interestingly there is a faint galaxy in here! It is the tiny IC2005 at 0.35'x 0.25' and is at magnitude 15.7...
