NGC891

This is a combination of data shot through 2 scopes.

2 months ago I shot a few hours with the 130PDS and I thought the result was decent for the little scope.

But recently I wondered why don't I use the large dob?! So I modified it slightly and it's obvious that the large aperture delivers.

Previous image was a 7.7h of integration. The new one has an additional 6.5h through the bigger newton, luminance only. Colour was used from the old one.

The new image and the old one for comparison are below.

Clear skies!

Wonderful improvement. The background galaxies are impressive too.

Definitely darker background and finer detail in the new one, some of the barely visible smallest galaxies in the first shot, were a struggle to find, but easily visible in the new shot.

21 background galaxies i could make out, had fun searching.

Big improvement. A magnificent image. I agree also the back ground images are impressive.

Many thanks, all!

I counted at least 40 ?

That’s a great result, this is one my favourite edge on galaxies, and your image is right up there with the best I’ve come across.

Thank you so much!

I've a feeling that I won't revisit it too soon. Maybe some colour with the same scope would have improved the stars shapes/colour, but I don't think it's going to happen.

I'm changing the scope for other targets now.

Great image, well done!
