1st Ha image, M27

I picked M27 as my first HA image, bright and well placed. Probably only my 5th or so CCD image. Most of my attempts haven't been worthy of posting. This one is OK but there's still plenty of room for improvement, guiding problems all night.

Here are the details:

110 minutes total, 10 minute subs, 13nm Ha filter
AP140 F7.5 EDF prototype
Losmandy G11, (standard)
SBIG ST-8E (parallel port)
CCD Soft for image acquisition
CCD Stack for aligning and stacking
Photoshop for final processing

Let me know what you think,
Robert

Hi Robert,
Its a nice one. I also use a 13 nm filter. I see many others are using 6 and 4 nm emission line filters. I wonder if they yield better contrast?? I suspect they do but probably take a little more exposure time.
