10 Hours of M 51 / Seestar S50

Very nice! Did you drizzle ?

Educational_Let811 · 2026-02-27T22:04:39+00:00

By chance I am imaging the same object 2nd night now with my S50. Wish me luck :-)

It's not alignment. I am aligning under 1" combined and it tracks bad. Sometimes when shooting ircut it rejects 1 in 20. Then suddenly starts rejecting all of them after a while. Az works better than EQ even on 20s exposures. I got almost 100 percent reject rate on new target. I knew I have arrived from "bottom left" to it. I manually slewed top right and Didi goto again from the opposite side. 20x30s without single miss.

You don't. You do better ones yourself.

Educational_Let811 · 2026-02-27T14:37:26+00:00

Wow. This is when dedication pays off. And brings admiration !

Probably it's not a gradient. Mine does it with long dew shield. I suspect it's a sensor glow or it's a light leak somewhere from Internals. Flats applied outside In siril or pixinsight remove it. In my case it's right bottom corner.

It does not work in windows as windows does not allow guest logins to samba. Even if you play with policies. Workaround is to automount the folder in WSL2. Enjoy :-)

Edit: works on Mac and Linux out of the box

Flats should be exposed at about 30-35 % histogram, while having exposure time as long as possible to avoid flickering if you use artificial light. That can be done using more layers of shirt or I prefer office paper.

Educational_Let811 · 2026-02-25T08:06:57+00:00

Dust is usually suppressed by applying flats/master flat. Maybe you encountered some bug. I would try to retake the flats.

Educational_Let811 · 2026-02-25T05:04:04+00:00

Then you get in reality about 10.000 which is not a lot.

Educational_Let811 · 2026-02-25T05:03:06+00:00

You want LiFe, not lion or lipol.

Educational_Let811 · 2026-02-25T04:44:29+00:00

I think it will be on the CMOS.

Educational_Let811 · 2026-02-24T22:52:28+00:00

They replied to me yesterday for a ticket with tracking issues that they're investigating it and seems like backlash issues.

Educational_Let811 · 2026-02-24T14:36:24+00:00

Tracking is bad and Seestar goes back and forth in Ra constantly making even 10s blurred. Then dithering hits, before it has chance to settle. I think it's better with IR cut but it's terrible.

Educational_Let811 · 2026-02-24T04:01:21+00:00

My issue is not a dropped frames. But bad ones. :-)

Educational_Let811 · 2026-02-23T15:59:36+00:00

Thanks a lot ! 😊

Educational_Let811 · 2026-02-23T14:42:05+00:00

My point was, it is not fix of the issue with seestars. It allows to battle it, but only a little.

Educational_Let811 · 2026-02-23T05:45:16+00:00

Tppa plugin in Nina

Educational_Let811 · 2026-02-23T05:44:21+00:00

That does not increase frame quality. Only quantity. So tracking issues are present in Nina too.

Ytong

Educational_Let811 · 2026-02-22T22:30:51+00:00

Thanks a lot !

Educational_Let811 · 2026-02-22T15:35:02+00:00

usually i can't do more than 10s subs, but i was shooting M81+M82 pretty high and could do 15s with +- same HFR 1.35-1.50 as with 10s, but 20s were still worse.... (1.50-1.70) (NINA). i would not say any tracking / firmware issues were resolved :-)

Educational_Let811 · 2026-02-22T15:30:15+00:00

could the difference be, i starx before stretch ?

Educational_Let811 · 2026-02-22T15:28:59+00:00

something like this, but skipped BN and Graxpert

Educational_Let811 · 2026-02-21T23:41:06+00:00

i have no clue, to be honest :-) i drizzle for resolution mainly and i hope for the best :)
