C4628 The Prawn Nebula, lies 6000 light years distant. I started this on on April26. I would have more data but the scope fogged up right down to the main mirror. It was also difficult to process as the CLS can mess with the colour balance.
This is a composition of 151 subs with a Baader Semi-Apo filter and 140 subs with an Astronomik CLS over two nights for a total of 291 x 30 seconds. 8" F4 Newtonian, Pentax K-5. Astrobin --->
