Saturn 12th April

The seeing was pretty crook when I first started tonight, but really settled down around 22:30. If I can capture something like this, then all I can say is what kind of spectacular stuff John and Tom are going to produce. I stayed out as long as I could, but I wanted to leave some time to process and get some sleep before heading to work in the morning. Captured at 12:42 UT.

8"SCT, 4 x Powermate, TouCam SPC880 flashed to SPC900NC (MerlinCam), 10 fps for 300 sec (3000 frames), stacked and processed 2896 frames @ 95% quality in Registax 5, tweaked in PS CS5.

Started out with a much better colour balance in the capture and this has made the process so much easier (still might have cooked it a bit too much). Pretty rough and ready process as I wanted to get at least one sequence processed before hitting the sack.

Thanks Ray,

Very happy with the result... not in the same class as many of the other posters here, but I'm cool with that.

I just put another sequence in Registax last night/this morning when I went to bed, and had a quick look at it this morning. It seemed to have similar ghosting that someone had in one of the other threads. I will have to check if it was the one I captured right after dedewing the corrector with a hair dryer. The image took a while to settle down... tube currents I'm guessing? Could be that the Powermate changed alignment as well... does not bode well for ~40% of the data I captured last night in that case... hmmm.

Cheers
Tony

I tried that night as well, I didn't get any dew and I still got a vague ghost to one side - not sure what that is.
Your final product is way better than mine, but as you said - you're happy with yours, and to be honest for the amount of work mine took, I'm happy with mine too.
I had fun doing it and I got to check out Registax6.

Lovin ya' images Tony. Well done.

A favour pls, take a print screen shot of your capture settings (gain, shutter speed, gamma etc - the whole shebang).

Logie.

That part is a work in progress, but I think I had pretty good settings last night, but the seeing was also pretty good. I'll check it out tonight and post the shot.

Good job Tony, reckon the Saturn addiction has struck for sure.

Certainly helps to get the colour balance as close as possible during capture.

Well done.
Regards
Trevor

Trevor, how do you achieve focus on Saturn? Same method as Juptier (try and reach / pin point focus on the moons?)

Hi Logan, in poor seeing it is extremely difficult as it will be going in and out of focus quite rapidly. In more stable conditions I try to make the edge of the rings & Cassini division as sharp as possible.

Hi Jen, I was just putting forward a theory, I thought that the ghosting is coming from tube currents created by the warm corrector plate.

I've tried Registax 6, not sure what I've done wrong, but when I have a chance I will go back and try it again. At this stage I'm finding that 5 does what I want, so I'll stick there for a while. Good luck with you imaging Jen.

Image is just showing the now fainter storm which less than perfect seeing kills, seeing for me has been pretty good although variable, getting a few clear nights run so you may get better seeing? I find Regx5 gives better disc detail and Regx6 better ring detail but Regx6 is so much quicker.

John.

Thanks John, I will be doing the full treatment on my data when I get home... Unless I'm imaging .

I had a quick look for the storm when I saw Trevors thread but I'm not convinced I can see it. Looking good out the window right now, might have another late night.
