Hi.

This is a large Nebulae cloud surrounding the bright star Gamma Cygnii.

The Nebulae seems to emit mainly in H-Alpha,as i could,nt bring out any other Gases.

This is a Narrowband Bi-Colour image taken with a 80ED and a HX916 ccd.

H-Alpha was 6x600 secs.Oxy111 was 18x600 secs.

Oxy111 was used in both the green and the blue channels.

No Oxy111 data can be deduced from this image.

Thanks for looking.

Mick.

Hi Mick,

I downloaded your image and had a look at it. Very strange on at least two counts.

The Ha is very smooth ( Too smooth ) and has black dots all over it in a grid pattern. I can't say I've seen that before so don't know the cause.

There is a ton of OIII in the area and I've included a rough OIII only copy here for you to see. I'll admit your area is off to the bottom left but it's pretty much the same.

18 x 600 should be good enough to see something but yours is, as you say, empty of any detail whatsoever.

I think you'll have to start over with the calibrating and stacking. Does a single Fit show any OIII ?

Dave.
