Thanks Andrew, I tried it with 3x drizzle- first time I've used drizzle. I liked it and will use it more often from now on.
A few points:
-after drizzle, it didn't require as much saturation, I just guessed and used 1.650 instead of 2.000/2.300
-the registax wavelet numbers I tripled and then adjusted slightly from there
-reduced back to 50% size
-unfortunately I got a bit of an artifact on the rings near the left, possibly an alignment point issue? May need to be restacked.

edit: actually I think I forgot to autobalance! I'll have to do it again- that might be why it didn't need as much saturation.

Second attempt, with autobalance this time! It did make a difference to the saturation required, this time I used 2.200- everything else the same:

Third attempt, with a bit less saturation at 2.000, little bit more noise reduction, and a bit bigger at 66% instead of 50%:

Nice Nick, don't forget that auto-balance smile.gif.

 

Now you've just gotta have a look at that ring artefact ...

I was just wondering about that. Perhaps it was a foreground object or background star?

Hello;
That artifact you have to review the video and if it were a meteor it would be seen in the video.
Also review, the video in case the planet ever loses the ROI.
Greetings

I haven't been able to get rid of it yet. Don't think it's a meteor or star because it's not in the normal size image- only the 3x drizzle one.
I've restacked 3 times with different alignment points and that made no difference.
It seems to be appearing in registax when I select "do all".
It "does all" in block sections, making a line right across. When it gets to 100%, most of the line disappears- except for that little bit.

I have seen that happen in Registax and got rid of those lines by reducing the number of APS. (reducing I think it was).

Can you upload a screenshot of your alignment point squares from AS3? That might help ...

I don't know how to do that but I can try later on. The 3 different alignment points I tried were:
-size 24, min bright 20, 117 AP's (multi size)
-size 48, min bright 10, 88 AP's (multi size)
-size 64, min bright 10, manually add alignment points to 80 AP's.
all had that artifact. Maybe I just keep trying and see if I can find something that works.
Had no problems using 3x drizzle on the image from the 27th:

I know I am no expert in this but I think you are using too many aps. I remember Emil saying not to use too many and to make use the multi option. From memory I select the 34 or 38 size option for about 34 to 40 something aps.

Hmmm, weird. And the fact it worked fine with the other one about the same size means that it should work ...

 

There's either something in the data, or something in Registax. Did you try pressing the "View full image" box? Or not? Restart your computer, shut down other applications, maximise Registax, might be a memory issue...

No, I hadn't tried "view full image" and maximizing Registax- but when I did the line was still there.
I also restacked it again with bigger and less alignment points (31 AP's) but that didn't work either.
I've tried everything I can think of, I could send it to you and see if it does it on your computer.
I should be able to get better Saturns as it gets closer to opposition, but I think these 2 with the 462mc are
already better than I got with the DSLR at opposition last year.

Looking good, maybe just a glitch with the other one.

 

You can send it to me if you like, but we're all using the same software, not sure if I could add anything...

I finally worked out what was causing that ring artifact. How I found it was I thought I'd try and process the video after that one and hope the line wasn't
in it. It wasn't quite as good, but close. But the line was in that one too! So I knew it wasn't an alignment point issue or something in the video.
I clicked the box in Registax "show processing area" and the line was just outside that area. So it was just a matter of moving that processing area
around until the line disappeared. Thanks Andrew you were very close with the "show full size image" box- it was the next one right alongside it. That's
probably what made me try it and it worked.

Glad you finally got to the bottom of it!

 

In the Settings area of Registax, there is an option for setting the default processing area - try setting that to the maximum value (2048) and you should be fine from now on.

 

On really large images (ie extended images with moons), if the entire image has not been processed then it should tell you before saving the file to press the "Do all" button, otherwise parts of the image will not be processed.

 

Andrew

Thanks again, that would be the proper way to do it- I just moved the area a bit till it worked.
It was set on 512. Knowing what was causing it now, if I had sent it to you it probably would have worked
if yours was set on 2048.
