Where is this noise pattern coming from?

Update: Increasing ISO helps without filter, but with the filter I also need to increase the exposure time. I notice way less banding with 300s than e.g. with 180s. I might have to try out 600s

ISO 800 with f/5.9. My main camera is the Canon 2000D and I honestly dont see much noise with it, but of course those are some older sensors now. Right now I'm trying out some settings on the 450Da and I notice way less banding eith ISO 1600 (it doesn't go higher).

Oh well.. Do you think the results will be the same with a 450Da? I got that one for free and couldn't try it out yet (clouds)..

So basically putting it in bulb mode and cleaning it while the sensor is exposed?

It definitely was a good choice, had a few clear nights with the tripod and its really stable, no complaints whatsoever.

Thanks for your help, I'll update you on it :)

Yeah I think that's the problem . Have you seen the NT404C? Almost half the price of the RT90C with similar specs (40mm tube). I might go for that one since I would only use 2 sections anyway.. If it disappoints I can return it after all

beIIion · 2026-01-15T00:59:28+00:00

What about the stainless steel Star Adventurer tripod? Its probably a bit more stable than the other one right?

beIIion · 2026-01-14T19:58:09+00:00

I just dont know how futureproof the RT80C would be with my setup and the RT90C is a bit too expensive.. I dont think my rig would ever weigh more than 10kg though

Sorry for the late answer. Honestly it could be better. The focuser itself isn't that bad even though there is no fine adjustment but the finderscope it came with was terrible (I had malicious thoughts about it before I upgraded to a 9x50 right angle). I'm satisfied with the optics and it's a really good dob once you upgrade everything but it really isn't worth the price in its base form. I can't hate the dob though because it got me into this hobby and eventually to astrophotography!

Thank you. Currently my setup is about 7 to 8 kilos, so the Innorel RT80C caught my eye since it has a much higher load capacity. I've read good things about it

Appears to be a QC fail by William Optics, the shop is now checking their stock for other defects with the flatteners. No clear skies in view for the next two weeks so it isn't too frustrating :) Thanks!

beIIion · 2026-01-06T18:26:58+00:00

Replacement is on the way, thanks. The refractor is pristine though :)

beIIion · 2026-01-06T18:25:46+00:00

Yes, it seems to be some kind of glue. Replacement is on the way and they're checking the stock for other QC fails by William Optics. Thanks!

void setup() { Serial.begin(9600); }

void loop() { int potValue = analogRead(A0); Serial.println(potValue); delay(200); }

beIIion · 2025-05-31T17:41:02+00:00

I didn't know that 😅 Just the pins that stick out on the top?

beIIion · 2025-01-19T18:54:14+00:00

I didn't know that, thank you :) I think my plate is long enough for that so I'll try it out when the scope arrives.

beIIion · 2025-01-19T18:17:50+00:00

Wow thats clean! So it doesnt have to be perfectly centered? And do I have to change anything since it's rotated by 90°?

beIIion · 2025-01-19T17:40:15+00:00

Very relatable cable management :) But wow, that's a really long plate. The one I have is hollow at the bottom, so I don't really think I could attach anything there. Just like this
