M27 - The Dumbbell nebula

[emyliano2000]

This week we had quite a few clear nights and with the moon being very big and bright I thought I should put my Tri-Band filter to the test.

I also didn't know what to shoot with my wide-field setup so I thought of trying the Dumbbell nebula even though it would look much better shot with a longer focal length.

So here it is, 99x300sec with my ASI294MC Pro, TS65 quadruplet and the Altair Tri-Band filter on the EQ3 mount.

I did my best to bring out a bit of the wings, I think some 600sec exposures would've helped.

The problem I have with the Tri-Band filter is that, even though I put it as close as possible to the sensor, it creates some massive, really ugly halos. It took me forever to process it without exposing them using small baby steps to mask the area after each tiny stretch.

I can say that I'm happy with it but I would be even happier if I could've brought out more of the wings.

To give you an idea, this is my first attempt in processing it but I really hated the halos and started all over again.

I really like the final result. It is awesome at full size. Well done!

Many thanks for sharing. M27 is one of my all time favourites.

You did well with the 2nd process, maybe a hybrid of the features you like in each image might be good.  I understand what you mean about the halos.

This is very nice - what a fabulous field of view! You have also caught some of the lovely outer halo that surrounds this lovely object.
