M27 with DSI Pro

First real night out with the DSI Pro last night and decided to re-shoot an
old favourite, M27.

http://homepage.ntlworld.com/chris.t.../M27DSIPRO.jpg

The image is LRGB at:

19 x 4 Min Luminance
6 x 2 Min Red
10 x 2 Min Green
15 x 2 mins Blue

I used the old DSI Colour to autoguide the poorly polar aligned LX90. Image
was taken at F/3.3
Happy with this as the first image in comparision to the older DSI Colour
and hope to improve on a few of the older snaps too. I've also pasted an
earlier attempt with the Colour DSI for comparison
http://homepage.ntlworld.com/chris.taylor9/Temp/M27.jpg although I'd gamble
that a little more experience gained over the last year would improve on
this shot with the Colour DSI.

Regards


Chris

Nice pic.

It took me a moment to work out that those two are the opposite way up!
Although the newer image looks a lot crisper, it seems like there is more
detail in the older one. You can see the less bright stars around and a
little more of the structure of the nebula?

Hi Mark

Not sure about this, I'm guessing that the older DSI Shot was overprocessed;
quantity over quality.. I may try the DSI Colour again one of the days to
see if I've gotten better at this. It's worth noting that the newer shot has
much more exposure time also but wasn't worked on half as much. I also use
neat iamge to clean the shot up a little, this is done at the expense of
some detail.

Regards


Chris
