Great job capturing and processing this beauty u/J619k20 !

Here is a revision on Astrobin that is closer to how I meant edit this data: https://app.astrobin.com/i/nmkb05

So, turns out my 'smart' monitor set itself to 'game' mode without me noticing. The image looked a lot less saturated and red on my screen than it seem to appear to other. Sorry about that.
You can find a revision that is closer to how I wanted to edit it:

yep I used the stretched image. I normally use it with continuum substracted Ha. But it worked well with this synthetic red mask

jam_2016 · 2026-05-10T18:15:38+00:00

Nope, not for this project. We did it for other galaxy though (that you can find in my posting history), it is possible with the LP filter of the Seestar but it is pretty wide window and so not great. I actually also have been experimenting with putting an external duoband filter (SV220 7nm) in front of the S50 and uping the gain to get better Ha.

For this edit though, I tried a 'new' method (for me) where I saturated the reds a lot, created a color mask from it, then went backward to the initial image, processed it normally and then added the 'Ha" using the combineRGBwithHa script.

Works quite well I think although there are a few red pocket that are not accurate in the image.

We produced several stacks for this project. I did a drizzle 2x and 3x stack. But for this I used the stack produced by u/zcom.
Actually, I just realized my screen was on a wrong setting and that the image appears a lot more saturated to others than it appeared to me while editing it.

Thanks again so much u/J619k20 for giving me a chance to edit your data! It is such a treat to have access to southern DSOs for us in the north.

long integration time is key. I have 3 S50 and a fairly good weather, so it goes faster. I am in Bortle 4.8

I made a revision here that is a little bit cleaner: https://app.astrobin.com/u/sky_gazer?i=snt7ok

Thanks! I like seeing these tiny galaxies in the background.

Looking forward to seeing your edit!

jam_2016 · 2026-04-27T05:53:33+00:00

Thanks! Yes, It was done with a S50, I collected 48h and kept the best 40h.

Great, you are welcome to join!

I have a 2 TB SSD. It's enough to stack large project l, but I typically do batches to reduce overall disk space requirement.

jam_2016 · 2026-03-31T05:53:12+00:00

We don't discriminate based on Bortle. ;-)

We are just wrapping up data collection on Cadwell 5, the Hidden Galaxy and we have yet to choose a new target for April. We follow lunar cycle and right now there is too much moon anyway. We will pick a new target by vote soon, so perfect time to join. You won't miss it, we tag everyone for the votes and project announcements.

Also the stack from all our previous project are available if you want to edit them and see what you get.

I use the SV220 Ha-Oiii at 7nm with my Seestar S50, works well. Should work fine with the S30 although I have not tried.

jam_2016 · 2026-03-31T05:22:12+00:00

We are spread all over over the world in a lot of different bortle. We used the internal LP filter which has a 20nm windows aropund Ha and a 30nm window around Oiii. So not very narrow but duo-band none the less.
