This is a work in progress and just a screencapture from NINA. I'm capturing Ha data this evening and thought I would share the very beginnings of my latest astro image.
Details below image.

Explore Scientific ED152 f8 1216mm scope with 0.7x reducer, ZWO2600MM camera, Chroma 3nm Ha filter, iOptron CEM70EC mount
1x600sec auto stretched in NINA, screengrab.

Cool. Interesting to see how this WIP will be developed. Even in this screen grab you can see a lot of data.

I’m glad to have you aboard, Greg. I always looked when I saw your name in New Posts on POTN, knowing it would be good and I was never disappointed. Your work is great.
 
a very good start. Do you use Pixinsight?
Thanks Jeff, yes I do use PixInsight. I was in the middle of acquiring the data last night when I took this screenshot from NINA before I went to bed. Hopefully it was able to complete the imaging sequence and I'll do a bit of Ha processing this morning. I should have been able to capture 30x 600sec subs. We shall see.
 
Very nic3e. I'm always amazed at all the stuff up there. It's almost hypnotic.
 
Not bad for a start. Eventually I'll get more data and different filters to make a color image from this but for now I give you 26x 600sec subs on IC1795, The FishHead Nebula.

Very nice! and that is a nice scope.

I have a Lunt ED100 achro, a Celestron HD 8", and a Skywatcher 120mm and several ZWO cameras, but my skies are Bortle 7.5 to 8, I live 300 feet from a major mall.

I also use the 16" Meade at the Skyscrapers of RI club scope (in my avatar) as well as belonging to the SLOOH observatory, a subscription observatory were we control the scopes and have some control over the cameras, they have 17 and 20 inch scopes in the Canary Islands, Chile and soon Australia.
Mostly from home I do SOLAR

I have a Lunt80mm DoubleStack Ha scope, StellarVue SV70T, old school orange tube Celestron C8 circa 1977-78, and the ED152 mentioned above.
I also still have an Explore Scientific ED127 with a nice Moonlight focuser on it that I really need to part with as it hasn't seen light in several years.
I'm in a Bortle 8-9 area, Henderson, which is a suburb of Las Vegas, so yeah, I understand the issue with light pollution. I'm very curious to try the new Antlia Triband RGB Ultra filter and see how it works under my conditions. It might just be a game changer for shooting RGB in the suburbs.
 
I knew a solar imager from Las Vegas on the Astronomy on the Net forum and the "Skysearchers" forum. I was always amazed at the DSO stuff he did.

I have a Lunt HA 50mm with double stack, a Lunt 80mm double stack and my Daystar Quark that I can put on my regular refactors. I have too much camera gear and telescopes.

I'm on TheSkySearchers too. Curious who it was because I thought I was the only Vegas area guy there? I go by AstroBee over there because I'm also a hobby beekeeper as well.
 
It was Lowjiber, John from Vegas, he was on AF.net not but hasn't been heard from for some time after they closed and most people moved to the Skysearchers.

I am Ben Cartwright SASS there, haven't done much posting as I was very involved with Ham Radio for the last year.

Yes, I remember LowJiber, he was around TheSkySearchers for a bit. Looks like he hasn't posted since Feb. 2022. I hope he's ok. I'm actually a mod there. I had no idea he was a Vegas guy. I should have reached out to him.
Yes, I thought your avatar looked familiar.
 
I really need to do more Solar pretty soon Cycle 25 will be waning. Deep sky is tough as since I stroke some years ago I find I really need to sleep from 9 pm to 6 am.

I am a member of the SLOOH observatory, Astronomer member, I have been gathering tons of data, fits images, of various objects using the 17" and 20" scopes in the Canary Islands and Chile (soon to have Australia) but have been doing much processing because the wife doesn't want me on the PC that much as as you know between photography and Astronomy most of it is computer time, expect the hours I spent by the pond looking for BIF.

Some people feel that remote observatories are cheating, and I agree some are as you tell them what object, say M45, you want and they will send you a data file in a month or less with the fits images, but they choose the scope, day, time camera etc.
Slooh on the other hand you set up the imaging run on a telescope, tell it what filters to use and you can even slew to a specific point in space (RA/DEC) which people use the scopes for to try to find comets and asteroids. Then you have to determine the day and time, you can set up a run up to 7 days in advance, and then you have to deal with wind, clouds, satellites, moon glow, rain, basically just like running your own scope in your backyard. only you are one of many who use a scope.

Here is a screen shot of an imaging run I am doing right now for Caldwell 67 the x-ray galaxy. it is grainy but with enough imaging runs over a number of days months you can build up enough data to smooth out the image. my username on SLOOH is WX1USN my ham call.
I just get so busy doing stuff

Two nights of data on the FishHead with the Ha filter. Not a great deal of difference at a glance between this one and the previous post. The previous post was a single night with 27x 600sec and this image is that same 27 subs plus an additional 48subs for a total of 750minutes or 12hrs 30mins of data. As I mentioned, at a glance you can't see much difference. except there was a lot less noise in this version.

Astronomy and Celestial is by far my favorite area to browse. Some of the DSO and planetary imaging you guys do is out of this world, figuratively and literally.

I have a request for you experts. I’ll send a PM later today if you don’t mind.
 
I'm still going to call this one a "work in progress" but I guess it's good enough for this year and figured I'd share it here.

Stunning.. Almost look like that space art the street artists make. Other worldly.
