M97 - Owl Nebula in Ha/OIII

Recommended Posts

Hi All,

Captured this across a couple of nights (hasn't the weather been Rubbish until very recently??) - Ha on April 1st and on April 18th. The seeing on the 18th was absolutely amazing (Lightbucket was over with his dob - saw several galaxies I've never seen before - wow!)

Anyway, here is the result - I think it came out very well :) :

Hi Richie - great image - almost ghostly... Q:- what is the circular artifact at 8 o'clock in the image ?

I think it came out very well indeed.

The owl's eye's are very clear indeed.

Thanks guys..

The artifact - I can barely see that on my monitor! Just checked my monitor calibration, and its accurate.... I can see it when I highlight the image though, so its there. Must be a dust bunny which the flats haven't taken out quite properly - I'll have to re-subtract the flats :) Thanks for spotting that!

Cheers,

Richie
