Orion 50mm Ha + Mystery Nebula

[swlloyd3]

Got out last night to snap this one - moon was fairly near so a bit of a gradient to deal with as well a house getting in the way so lost around half the subs.

This was just 12 x 6min lights // 11 x darks (battery ran out) // 39 x flats // 50 x bias.

EOS 12nm clip Ha filter. 

Canon EOS 1000D

ISO 800

Asahi SMC Pentax F1.4 @ F2.8 (going to go to F4 with this next time as had to crop due to messy corner stars)

Astrotrac

DSS + PS

After Orion went to close to the house, I decided to see if I could get away with a 10 min sub on the astrotrac at 50mm. Pointed the camera straight up and shot away. Pleasantly surprised that the stars were nice and tight! and even more surprised to see I have captured another nebula! - So I centred the image and shot away at 6 minutes. Below is the result with the same Darks, Flats and Bias applied.

This is a crop as image was still slightly off centre and corner stars were not so good. I think it might be the Heart and soul nebula? but not too sure? Any thoughts?

Looks like IC405 and IC410 to me

I would tend to agree with Martin on the nebs in the second shot...

Thanks for info! Was pretty happy to have captured them Now to work out how long I can get with a 300mm lens

@martin_h - what is the software or website you have used for identifying the nebula?
