Observatory First Light - Jupiter

[Radar]

First time I've tried Jupiter. And basically first serious use of my Imaging Source camera not to mention the observatory.

Finally got my Meade mounted on my G-11 with the dovetail plate. Amazing what a steady mount can do.

I think seeing tonight was brilliant. Jupiter through the eyepiece showed awesome detail, and to my surprise this detail was easily seen on the laptop screen.

This is only my first attempt, and there seems to be some kind of interlacing problem with it (strange lines at the top and bottom). Probably a setting somewhere.

Taken through an eight inch SCT LX50. I took 2000 frames, only placed 900 in registax because 2000 seemed to stress registax out a bit. I stacked all 900frames as well. I was just experimenting here and didn't bother throwing any away.

How do I throw away bad frames?

My biggest problem I think is the interlacing. I can't use wavelets properly, because it exagerates the interlacing. Any ideas what causes the interlacing?

Comments and suggestions welcome.

Not bad Pop's, :welldone:

Did you constrain proportion's when you did the crop, it looks a little elongated at the poles, instead of the bands...

I haven't had that problem ...yet. Sorry, can't help you on that one.

Your frames are chosen on two factors. The percent you set, I think default is 80%(little box on the right after you have selected the video to align.) And where you place your alignment point.

The alignment point sets the quality level it will base your calibration frames on. I usually click on several different points within the image, to try and find a point with high image quality. You can however, click the 'view framelist' box, and manually uncheck any frames you do not wish to process/align. (I use the quality % box myself.)

The wavelets, to me act like a sharpening function. I.E. 1:1, through 6:1, combined(do all) on all the frames.

The easiest thing to do is download the registax version 4 manual. It's a good read, not but a few pages long and goes into more detail on the wavelet/interlacing process.

After you use that little cam a few times and get familiar with RV4, it's actually a fun little set-up, with great results.(like your Jupiter.)

Matt's learned a few tricks too, I'm sure he'll have some helpful input as well.

first lights gotta be a buzz mate. are you loving it!

Great first light Ray. Looks very promising.

What exposure setting, gain, etc did you use?

[Radar]

Thanks guys.

Matty I can't remember. I just fiddled with the settings so that the histogram was close to 250. I have to start writing this stuff down.


What's the best way to focus one of these things?

Great image Ray. Well done :woot: :woot:

sorry I cant help with your questions as the last planetary image I took was about three or four years ago and I gave up after that..but congratulations on firts light

I am just surprised you didnt go for a DSO :) ;)
