Old fave to start the season, North America Nebula.

Start of a little experiment this image.

This is captured with my secondary rig and I'm going to continue to get data and post the result to see what the improvement is, obviously it will be subject to processing variations but something I've always wanted to do without tying up my main rig for many sessions.

So here goes, first rendition is 3 hours captured in the small amount of astro dark we have currently.

Great widefield image and wow the number of stars - that always gets me when imaging into core of the galaxy - really good star colour.

That's a belter David. Love the pink highlighting around the edges, it really helps add depth to the image.  Gary

Thanks Peter,

I've always aspired to try and achieve your star colour in your images (some way to go yet 😉).

 

I think having access to dark skies and therefore having only a UV cut filter is a massive step in the right direction.

Managed another 3.5 hours on this little project, this time from a darker location but plagued by a strong breeze and eventually a last quarter moon.

 

Very hard to process in the same way as the first rendition, but I did note that it was much more forgiving when stretching and saturating, virtually no noise and a smoooooth image is the result.

 

I think some of the dark areas are more interesting to look at and star colour is deeper.

 

So my personal verdict that there were significant gains in doubling the data, I will give it another bash next opportunity till the improvement stops.

The wall is showing stronger in this rendition as are the other strong Ha areas. I also like the dark area contrasts.

i agree, definate improvement in contrast and star colour.

This is another 3.5 hours of data but I went through all 3 sessions of data and binned any that weren't perfect so ended up with 7.5 hours of data (225 x 2' subs) out of the original 10 hours, certainly the most I've had on one target.

 

I'm struggling to see any great difference from image number 2 despite several processes to do so. Processing them the same is not easy at all.

 

So I'm going to call it a day on this, and my conclusion is that there's probably no great value in going over 10 hours of data, certainly for my particular setup/skies/processing skills.

I really like that, great colour in the stars
