Last night I added more data to the Prawn nebula IC4628. I'll probably leave this now and go shoot other goodies in the area.
Looks okay I think, the blue stars break up the red Ha to give it a bit of colour. The final is 123 x 1 minute subs at ISO 3200, ED100 at F7.2, Lumicon Deep Sky filter, Pentax K-5. I need a new filter. The coating on the old one is worn which bloats stars. But that is something I don't mind in the right context.
The ED100 running at F7.2 and the K-5 in winter are a good combination. But then winter is a good combination with anything here in the tropics. The cool temperatures make for low noise so I'm making the most of it before summer comes and ruins it.
