11 hours of Horsehead and Flame Nebula

[MarkS]

I don't think I'll be able to shoot more data for this so I spent a rainy Sunday afternoon processing it.

Imaged over 2 nights: 18 Dec 2011 (temp: -4C, SQM: 20.9) and 16 Jan 2012 (temp: -1C, SQM: 20.85) at High Halden
130 x 5min at ISO 800 with CLS filter
8 x 2.5min at ISO 400 with CLS filter

The usual H-alpha modified Canon 350D on the Takahashi Epsilon 180ED.  
EQ6 mount guided with a 300mm lens with a QHY5 stuffed in the back.

As a comparison, the 18 Dec data on its own was what I used to produce the "Rudolph" Nebula:

Nice one Mark.

When's the book coming out.

Strangely I was thinking a similar thing in respect of keepsakes for all these photos! I never bother to get photos printed now - just whack them into photobooks from "My Publisher" when they have special offers on. Its certainly what I intend to do if I manage some nice shots!

Fantastic Mark, there is detail in this image I've not seen before.
