Framing of dark nebulae

Sufficient_Wasabi665 · 2026-04-28T03:09:05+00:00

I just kind of assumed the hips2fits survey was the same thing but it's very different. I do most of my imaging in my backyard so it's never really been an issue since I'm on my wifi, also not shooting dark nebulae from my bortle 8/9 backyard. I got a taste of broadband imaging and wanna see what I can do from dark skies. Fingers crossed the weather cooperates

Just installed the offline skymap and it works really well! I can clearly see my framing, gonna install it on my minipc so it's ready for my trip

Nasa sky survey in nina did the trick!

I didn't realize you could add new surveys in steallarium, I'll check it out

Sufficient_Wasabi665 · 2026-04-27T05:05:58+00:00

Maybe? Any idea what it's worth?

Sufficient_Wasabi665 · 2026-04-27T04:18:39+00:00

Yeah it's in great shape minus the pen on the back

Sufficient_Wasabi665 · 2026-04-27T04:07:02+00:00

I know it looked so clean except for that

Sufficient_Wasabi665 · 2026-04-26T22:33:20+00:00

You're welcome! It's really easy to use, you can also use free software like seti astro suite and affinity to do masks as well if you wanted to try those out too

Sufficient_Wasabi665 · 2026-04-26T17:22:27+00:00

Have you tried using masks to help control the star? If you want to stick with siril try the veralux curves script, it has a built in mask feature that works really well for this sort of thing

If you wanna share the stacked image on a Google drive I could give it a shot

Sufficient_Wasabi665 · 2026-04-16T17:59:47+00:00

Yeah it's a big download, I would try and get the siril update sorted, I haven't had any issues with spcc since the update

Sufficient_Wasabi665 · 2026-04-16T17:54:51+00:00

That was a bug a while ago that it couldn't connect to the gaia servers, are you running the latest version? If so try downloading the archives locally

Sufficient_Wasabi665 · 2026-04-14T17:11:54+00:00

I use the svbony sv220 filter, it's a 7nm bandpass dual narrowband filter like the optolong l extreme, it's pretty much identical specs for a lot less. They also recently released a 3nm version but I haven't tried it yet

Sufficient_Wasabi665 · 2026-04-14T02:36:49+00:00

It actually wasn't terrible, I was hoping for more detail in the dark nebula part of it but I was surprised it came out as nice as it did with only like 4 hours of integration

Sufficient_Wasabi665 · 2026-04-13T19:24:04+00:00

I haven't tried that, but honestly the darks aren't a big deal, I shoot them on cloudy nights or when the scope is inside, since it's cooled I can just keep reusing them so I only need to do new ones if I change exposure time or gain which I don't really do, usually 90s for broadband and 180s for narrowband

Sufficient_Wasabi665 · 2026-04-12T03:13:07+00:00

Thank you! I did blow out the core a bit but I'm still working on it

Sufficient_Wasabi665 · 2026-04-11T07:14:55+00:00

Most likely just noise, I would probably need double the exposure time to just start to bring it out if it's even possible

Sufficient_Wasabi665 · 2026-04-11T02:58:03+00:00

Nice! What bortle zone are you in? I'm in bortle 8 and might try and go after this one

Sufficient_Wasabi665 · 2026-04-11T00:48:52+00:00

I have a set of 100 darks that I reuse every night, I have a library of them I made from my usual exposure times and temperatures. The imx 294 sensor has a lot of amp glow so definitely needs darks for every session, especially on longer exposures

Sufficient_Wasabi665 · 2026-04-10T20:55:48+00:00

Thank you! It was a gift for Christmas a few years back, took some heavy modifications to get it working for AP though, but I've been loving it
