NGC281

[astro mick]

Hi.

This is an image of the Nebulosity around a star cluster in Cassiopia,known as NGC281.

It was taken using two ED80 scopes,simultaneously taking both H-Alpha and Oxy111 Data.

Subs were 18x600 secs.

Alighned,then processed in Photo-shop.

Camera,s were a HX916(Ha) and a MX916(Oxy111)

O111 was used for both the Green and the Blue channels.

Thanks.

Mick.

Not sure Mick something doesn't look right, alignment look out some how

There does seem to be a diagonal shift from top left to bottom right!

Thanks everyone,as always appreciate the comments.

Peter and Bryan,you make an interesting comment about the alighnment,but i cant quite see it.If there is a mis-alighnment it must come from the alignment of two different fields of view,as i,m using different camera,s.I would have thought the stars would show this.

However i will look at this,and may PM to let you have the images.

Hi Mick,

There does look to be a mis-alignment, the stars seem to be duplicated. As an example, I've highlighted two pairs of stars that look as if they are the same pair:

As others have said there's quite a large shift in the picture. I've tried to highlight it here

[astro mick]

Your right Guys,how strange.Should have noticed this.

I will look at this again and re-post.

Thanks for letting me know.

Mick.
