dawson Posted February 21, 2014 Share Posted February 21, 2014 The GRS never disappoints. Nicely captured. What was the seeing like? How long in time was each of R, G and B? Do you have to re-focus between the different filters? Jd Link to comment Share on other sites More sharing options...
Johnnyaardvark Posted February 21, 2014 Share Posted February 21, 2014 Very nice GRS there Steve... Something I have never seen with my own eye's so look forward to that sometime. Is some of blurring there due to Jupiter's Rotation? Can you have too many frames? Link to comment Share on other sites More sharing options...

+Ibbo Posted February 21, 2014 Author Share Posted February 21, 2014 (edited) Thanks folks Steve-probably not the best time process them at 3am and I may have overdone the noise reduction at the end James 60secs each seeing was not too bad compared with what we have had of late but still not good and I do have to do 1 pulse of the focuser for the blue I use a Shoestring focus thingy and focuspal or the JMI focuser that has a DC motor Edited February 21, 2014 by Ibbo Link to comment Share on other sites More sharing options...

Guest speed Posted February 21, 2014 Share Posted February 21, 2014 Cool picture ....may get round to imaging later....but sounds complicated. Link to comment Share on other sites More sharing options...
dawson Posted February 21, 2014 Share Posted February 21, 2014 Speed, get on with it, Jupes is still at its best, but will just get lower in the sky. Do you have a webcam and laptop? JD Link to comment Share on other sites More sharing options...
+TasKiNG Posted February 22, 2014 Share Posted February 22, 2014 Hi Steve, I'm currently playing around with imaging Jupiter using my SLR and various teleconverters. I have had reasonable success but have only used 20 pics so far when stacking. Would it be possible for you to upload just a single frame from your stack please so I can see what sort of quality I have to aim for and if I am getting the required quality to be worth taking a large number of frames. Eventually I will get a proper imager and go the video route but at the moment I am enjoying experimenting with mu SLR Link to comment Share on other sites More sharing options...
dawson Posted February 22, 2014 Share Posted February 22, 2014 Here is a 1gig video of a capture of jupiter. https://www.dropbox.com/s/73a15qh0tz4brmx/Capture%2019_01_2014%2022_12_49.avi You should be able to scroll along and see the variation in frames. These are videos, not single frames per se. You need so many (1200 in ibbos case) as 30% or so will be rubbish due to movement or atmospherics. Then the software just takes the best bits (is how i like to think of it) from the remaining frames and stacks them to make the best possible image; tweeking the wavelets at the end of stacking also has a massive impact on sharpening the image.

+TasKiNG Posted February 22, 2014 Share Posted February 22, 2014 That's great, Thanks James. Will help me to try out the various stacking progs too Link to comment Share on other sites More sharing options...
+Ibbo Posted February 23, 2014 Author Share Posted February 23, 2014 (edited) same stacks re processed as RRGB and left at 100% instead of 120% still not entirely happy with it, having said that it probably has the makings of my best ever Jove image though I have load of other vids from the other night I have not played attempted to process yet or am I over processing slightly out of focus data that is also blurring due to rotation and over long video runs Edited February 23, 2014 by Ibbo Link to comment Share on other sites More sharing options...
+TasKiNG Posted February 23, 2014 Share Posted February 23, 2014 (edited) Looks good Steve. A lot better than my SLR images. I really need to get a webcam ( probably a Neximage 5 ) and do some video stacking. Just waiting for payday Edited February 23, 2014 by TasKiNG Link to comment Share on other sites More sharing options...

Just waiting for payday The ZWO ASI120MC (colour) or ASI120MM (Mono) are well worth a look if you plan on doing planetary imaging. If you go for the mono version you'll obviously need RGB filters to make a colour image. I use the colour version and highly recommend these cameras.

+Ibbo Posted February 24, 2014 Author Share Posted February 24, 2014 not sure if I like this version any better than the last now I've had a sleep Link to comment Share on other sites More sharing options...
dawson Posted February 24, 2014 Share Posted February 24, 2014 The detail looks like it should be excellent, but it looks ever so slightly like one of those 3d eye puzzles. Are the layers absolutely one on top of the other? I've never tried RGB anything so i don't even know if that is what has been done. Was this shot at the native F/10 or was there something else in between the scope and the cameras sensor? Jd Link to comment Share on other sites More sharing options...

Thanks Felix, I'll check out the ASl120MC as the Neximage 5 seems to get very mixed reviews Link to comment Share on other sites More sharing options...
