IC5070 Pelican Nebula

[Fenriz]

Hi guys

Another image from last night, its a large object so was not able to get the whole Nebula. Again the very strong orange glow must be down to no Flats, at least I hope that's all it is. Anyway here it is, you can start to make out the shape of the Pelican.

40 x 90sec @ ISO1600 + 20 darks.

THe vignetting is most likely street light glow combined with poor collimation. Yes, you should take some flats for that...

Also, if you image a star dense place on the sky and feed it into CCD Inspector (you can run that as trial for 30 days - DO IT!), it will tell you how curved you image plane is and how bad you collimation is.

It appears that you do not have a coma corrector. You need to get one. The Skywatcher one works fine, or you can get the Baader. Both are called "Multi purpose coma corrector".

For the 1000D, 800 ISO is most efficient when it comes signal to noise ratio, so step down to that.

Keep it up! It takes a while to find the sweet spots in AP!

Thanks for the comments, I have the Baader Coma Corrector, but like you say I think I need to sort out collimation and invest in a CLS filter.
