The bloody Barnard :)

[emyliano2000]

Well, here's something I've never done before.

Tough target for my f6.5 scope under suburban skies. Took me a while and I think it could be much better with some more data shot under dark skies but overall I'm happy with it.

55 hours and 50 minutes

Barnard 11 and Barnard 13 are dark nebulae in the constellation Camelopardalis, located in the south of this constellation. The nebulae are part of the Southern Giraffe Clouds. Also, in this photo, you can see the following nebulae: LDN 1399, LDN 1400, LDN 1401, LDN 1402, LDN 1404 and LDN 1408.

The image is illuminated by the Hydrogen-Alpha signal shown as the red background. I had an attempt to capture some of the extremely faint Oiii signal too (shown in blue in the lower right and center part of the image) but even after 100 x 600sec exposures I didn't get any structure in the fillaments.

Thank you Dave. It's not too bad when the target is high in the sky. I originally planned a LRGB photo but just when I finished with them, someone posted a HaOiiiLRGB photo that looked so good and I thought I should give it a try and see what comes out of it.

It's nothing compared to the photo that I saw but the guy was using an f2.3 scope under bortle 3 skies so I can't really complain.
