Seeing was atrocious last night, 1/10 if I was lucky. I tried RGB imaging on Jupiter, but was sorely disappointed at the fuzzball I saw.
I reduced focal length until I ended up using a 2x barlow on the moon to compensate for the poor seeing.
Here's the result of the effort. A 3-image mosaic centered on Clavius, with Moretus in frame above and left, and tycho down below to the right.
The image was taken at 30fps, which sometimes works and most of the time doesn't. But I've got a routine to switch between pause/stop until I get the preview showing, and then I can start recording. Frustrating, but it'll do for now.
10" dob on EQ platform
DMK21AF04 with baader IR block
30fps for 1 minute on each of the 3 areas. Approx 60 frames of each avi stacked, joined together in photoshop, then LR deconvolution in AstraImage, and then save to web.
Pretty happy with the results considering the seeing, and not a bad first luna light for the DMK.
I also forgot to mention I did MAP processing on each of the 3 images - that is, I aligned and processed on 2 spots on each avi. I could've aligned on more but didn't want to spend too much time on the data today, i'll try again tonight as the jetstream looks a bit better.
The new version of registax (currently beta, which I don't have ) will allow you to align on multiple points at once.. registax will then go through and align on those multiple points and blend them together at the stacking stage.
But in my case, it's simply manual MAP (multiple alignment point) processing. I ran through registax aligned on one feature, saved the image, opened the avi again and ran through aligned on a different feature, saved that image.
I took them into photoshop and copied one image on top of the other as a layer, lined them up, and deleted the blurry parts to show the sharp parts from the layer beneath.
It's becoming a common way of processing lunar images because of the scale of them, and the "wavey" type of seeing you get where in a single frame you can have one part of the image sharp but the other part not sharp. This way you align on multiple areas which will end up with the sharpest image of THAT area.
You then just need to join them all together in photoshop.
It'll be much better when registax can do it by default, as long as it does it well.
It's different on the DMK, asi. I had gamma set to "12" whatever that means. It goes from 10-20, but if you go over about 14 it really makes the image look ghastly (my new favourite word thanks to Bert )
being very new to pc myself (have only just downloaded registax now), how come ppl with other expensive proggies still use registax for a lot of stacking stuff? is it a 'different horses for different courses' type of thing?
cheers
