JUPITER in an all too brief moment of average seeing May 13th
Hi All, fired off a few Jupiter avi's last night. Prett shocking seeing when I started 3-4/10, it improved to say 5/10 when I took this one, but by 10:30pm had turned to crud again.
Usual sort of thing here. Gain 50%, Gamma 25% - other details on the pic. I was actually a little surprised it came out as sharp as it did cos it was fuzzing out badly every second or so with only very brief glimpses of any detail during capture.
Very nice mate, very nice indeed. Here is my effort from just over 1/2 hour later, at 22:27pm. I notice we both have the burnt out zone/belt at the top of the disc? Any ideas on that? My histogram bar was between 210 and 230 during avi capture.

Great image Dennis, reckon yours is a little sharper with more detail though perhaps a tad more grain. I was imaging in exactly that same exposure range of 210-230. I was thinking of seeing how I'd go with 190-200 and see if that helps with burn out. Note sure what detail there is in that region of Jupiter - expect it's a bit bland as well.
Amazed you got 479 frames selected from 900 with a quality setting of 97%. I've never been able to go so high with quality or I'd only get 1 frame. This one below was I think 276 frames selected when quality was only 90%. I wonder why? Are you using version 3 registax?
Here is a screen print from Registax 3. I used an alignment box of 128 on the 3 white ovals, with Quality set to 97% next to the Compress Method field.
I think I have always used Compress - not sure if that was the default when I installed Registax or whether I have some how made it the default? When I launch Registax Compress is always set as the default on my desktop PC. Must check my laptop later.
Is Gradient the more preferred method? I've not really explored all these options, does anyone know what they do or mean?
I was just going to say...if someone said that Gradient is better, there is no way in hell that I am going to go back and re-process the gazillion avi's I have accumulated....
Would be interested to see a comparison.. I use "gradient", I think most people do.
I'll reprocess one of my recent avi's using "compress" , and see what happens.
The quality estimator is used to determine the quality of each frame, so it ranks/sorts them in order after the "align" page, so that when you set your %, you get the best frames at the start of the list.
I guess it's an important feature If you're using a method that doesn't measure the quality accurately, you could be throwing away good frames.
In the worst case, a different quality estimator might be better in different circumstances. That means someone needs to figure out which one is best in varying conditions
Here is a composite screen print of my K3CCDTools settings from 13th May. It's worth showing these to get an insight into what settings I use and also to compare them with settings of others, just in case we are missing the optimum combination.
The "Quality Settings" panel seems to display every time I change the setting from e.g. Compress to Gradient. I have not touched the actual values displayed; again, they appear to be the Registax default, unless I have disturbed them in some other way?
It would be nice to attend a class room session with a Registax expert to go over some of these settings. I wonder if there is an expert attending any astrocamps, such as the Qld Astrofest or others, who could give a talk on optimum settings for Registax, as I am feeling my way along blindly, and only get to know of other’s settings when we post screen prints or have conversations such as this.
