Pelican from balcony - but what?

[perfrej]

Folks,

The automation is now more or less flawless and I can start the sessions up from my iPad or even my phone. The only thing I do not yet have is a good automated flat source and some kind of cover.

This is 27 x 10 minutes of Ha and 23 x 10 minutes of O3 mixed up with Ha in R, Ha*O3 in a synthetic G and O3 in B.

I am curious as to the blue shading up to towards the top right of the picture. I let it be because it is very evident in O3 as you get deeper. Maybe it is an O3 cloud in front of that part of the nebula. I'll investigate this and maybe shoot a really deep sequence of O3 just for verification. It is consistent in the O3 stack and there are no subs with occasional clouds passing by in any of the subs. Hmmm... Thinking

I would appreciate comments on the blue shade - and I do not believe it to be a gradient...

WOW!! That's amazing

Looks like a good subject for a wide angle image or maybe a mosaic

Thats fantastic ....

[steppenwolf]

That's interesting (as well as being a great image!) as I have also captured something similar here although my image is RGB taken with an FLT98 like the one you used to own:-

What ever that blue haze is, I can see a hint of it at the bottom of Steve's image as well....

Those are both great images! The detail is superb!

[perfrej]

That's nice Steve, and I conclude that it is the glare from Deneb and 55 cyg that is the main cause.

All the best,

Certainly the angle would be right for Deneb to be the cause - I am pleased to find that someone else has captured it though!

[prokyon]

Great result! So many details and I like the colours. The shining could be from Deneb?

[perfrej]

Thanks!

Yes, I have concluded that it is Deneb.
