Description

Oddly this got deleted... so I have re-posted it!

I took 52 subs of this at 4 minutes long exposure time. The moon was at 92.6% and it was notable on the subs that at the start of the evening they were quite light and lacking in detail, because of twilight, they then improved, but then as the moon rose, they became very washed out. The data was not at all good, considering, but I processed it as best I could. It was hard work with the gradients. My main reason for taking this was to check my guiding - I am pleased it is much better than before. I used my 8" reflector and my modified DSLR.
