I feel like chicken tonigh.....

Hi all,

Been a while since I posted anything, I had nothing worth showing.

The weather was hopeless here lately, when it did clear up for a while it was around the full moon time...

I spend a 9 nights across April and May trying to capture subs in between clouds coming and going. I ended up with 4.5 hours of 300s ISO400 subs through the Baader Neodymium and 25.5 hours of 1800s ISO400 subs through Baader HAlpha, Sulfur II and Oxygen III. Only 8 subs were needed for HAlpha since IC2944 is bright in Ha, but the reminder of time was used to capture SII and OIII, roughly the same amount of time on both.

I'm stoked with the end result, I dare say that this is the clearest and best of my images so far...

The Subs were captures using a full spectrum modded Canon 40D.... who said that DSLR is no good for narrowband.

The telescope used was the Bosma 80mm f6.25 refractor, on the CGEM mount, processed in photoshop, diffraction spikes added using "Astronomy Tools" PS Plug-in.

Thank for looking,

Mariusz

Nice work, Mariusz, especially challenging with a DSLR.

Great display of emission line distinction Mariusz, especially for DSLR work. Keep them coming.

Have to say love the colours here Mariusz, many seem to dislike the magenta in stars that can be apparent in NB images (which is to be expected) but provided it is not overpowering the image, I rather like the look

Delicious dinner, done to a turn. Excellent processing.

I agree with StrongManMike.

The more I use the DSLR the better my results are getting... I'm quite happy with the amount of detail I'm getting in narrowband with my 40D. I wish I had more clear nights... now I think were averaging 3-5 per month and most during or around the full moon.

I think that if the magenta halos are over powering then yes it can take away from the image and look strange and wrong, a slight purple haze on the brightest stars is OK for my liking.
