Registax Processing Help

[SyedT]

Hi guys,

Cloud cover finally lifted to allow me to do some imaging. Took quite a few frames of Saturn, but I'm struggling with Registax since I'm quite new to it.

I've attached the original tif file, and the rendered JPEG from Registax, which is the best I could do for now. I would really appreciate it if someone could have a look at the tif file and have a go at it in Registax, and just walk me through what they did.

Thanks!

You say that you took quite a few frames but you attached 1 tif. For planetary you would normally take a video (avi) to stack in Registax or better still Autostakkert.

How did you capture your images?

Hi Peter,

I used a ZWO ASI 120MC-S to capture the images. The plan was to capture it in AVI format, but unfortunately the setting got switched to PNG. I combined the PNG files in PIPP to get an AVI file, and then processed the result in AutoStakkert!2. The tif is the output from AutoStakkert!2 which I then had a go at processing in Registax.

We need more information. Telescope, camera, how many frames etc.

Hi Peter,

T: Skywatcher 200P 

C: ZWO ASI 120MC-S

Frames: 40,000 --> Best 25% selected in PIPP --> Best 1% stacked in Autostakkert!2

Cheers,

40,000 frames seems rather a lot. I would normally go for less than 4000.

Clear nights have been a rarity, and will be for another week or so at least. Plus I'm starting work in a few weeks' time so I'll have less and less time to play with the setup. You could say I'm overcautious I guess! I figured I'd rather have more frames than less.

IMO I would keep the overall exposure time to less than 150 secs.

Would that be due to the rotation of Saturn?

Syed

[PeterCPC]

There is a limit due to rotation but I'm not sure what that would be for Saturn. Someone else might chip in. I try to keep it to 150 secs to obviate changes in seeing conditions.

Thanks for that. What percentage of files would you suggest to stack in AutoStakkert?

[PeterCPC]

Try different combinations to see what works best. Try 60% and 25% maybe. It's all about experimentation really.
