Jupiter from 11th Nov (my first of the year)

Recommended Posts

Morning all,

Been a bit slow sharing this cos I keep trying to reprocess to get a better result - this one is from 90s captures in each channel, de-rotated the AVIs in Winjupos, but I've just aligned the final RGB images in Photoshop. I'm having real trouble with the RGB image de-rotation process in Winjupos; it seems to add loads of noise that's not there in the source images...? Anyone else seen this?

Anyway, this one is still somewhat noisy but I'm fairly satisfied considering I haven't done much with this equipment for a while!

I got several other captures that night so am considering doing a little animation just for giggles. Haven't tried that before.

Cheers folks

Jim

Some nice detail in there. You may want to try RGB align in Registax to help remove the red and blue rings. The "noise" you are getting from Winjupos may just be as a result of bad alignment, so you may want to check you have input the time correctly and play around with the alignment circle to make sure it is set properly on each of the R, G and B.

Thanks Freddie, I think you're onto something here! As for inputting the time correctly, it should be the exact mid-point of the capture in UT, right? The thing is it appears to be only accurate to 1/10th of a minute - so if it's (say) 00:00.15, I have to enter 00:00.2 or 00:00.3 when I really want to enter 00:00.25....or have I completely misunderstood that field?

I guess another useful thing would be to synch my laptop time with some online time server (do those things still exist?)

Cheers

Jim

My experience of this is that the time is not super super critical but does need to be right and depends to some degree on the quality of the R, G and B images. If you want to be as accurate as possible, you should use the time the reference alignment frame used for stacking from the AVI was captured. I think making certain the alignment on each image is spot on and the RGB align in Regi would give you the greatest improvement. Let us know how you get on.

Cheers for the advice Freddie. Here's a Winjupos reprocess with the time set to the start of the AVI, as I tend to use an early frame for alignment. Bit of NR in Photoshop etc., then a size reduction which I think helps a bit.

      I imaged Jupiter, Saturn and Mars this morning around 3.30am in the interval between 'high enough' and dawn.  Equipment: CPC800, ASI224MC, ADC. Captured with Sharpcap, processed with Registax6. Used best 20% of 5000 frame videos.
      It's so long since I did any planetary imaging that I had to re-learn what to do. The Jupiter and Saturn images seem under-exposed.

      Hi,
      I have a Motor drive for the 130EQ and when I attach and switch it on it drives the RA axis. But once its attached its very difficult to move the OTA in the RA axis manually. Am I missing something? Is there a way to easily couple & decouple the motor so the OTA can be moved manually?
      Is there someone who uses one of these motors who can help me pls.

      Hi everyone - juts purchased my first telescope and am asking for advice on what is best to be seen through this telescope as a starter - have already seen the moon and some distant stars and am comfortable with using all of the eye pieces included. What would anyone recommend?

      Hi 
      I’m attempting to get back into astronomy, previously owned a 150pl reflector but parted company with it several years ago, I like the idea of a Cassegrain style as one of the big factors Of letting the 150pl go. was storage and transportation of It! I am interested in mostly visual observations but would look to take a few pictures here and there OF planets and easy nebula/DSO., I feel that a Schmidt-Cassegrain would be the best suited, my main stumbling point is should I get the 5 or 6 version. Is the 6 under mounted? And is it worth the extra cash, obviously there’s a higher light gathering power on the 6 but would it be much better than the 5, I see that the % of lens obstruction on the seems high! As the secondary mirror looks to be the same size on both 40% vs 14%! Obstruction by area. Any guidance would be very appreciated. I’m not against the idea of upgrading the mount in the future to a eq5 maybe? But want in usable to start with.

      Hello all!
      A question for all you Starsense users out there ...
      When I do an auto align with Starsense, it duly goes through it's routine of moving the scope to different star targets and resolves each one fine (5 targets I believe).  Then it displays on the handset "StarSense Ready".
      At this point the telescope tube is always pointing in some random direction - is this how yours behaves after it finishes alignment ?  Just pointing at the last star it used as a target reference ?
       
      At this point I usually set my scope to go to it's "HOME" position, but whenever I "GOTO" a target it is never in the scopes eyepiece and I have to manually hunt around for it.  (Using a wide angled eyepiece).
      Should I just "GOTO" a target without going to "HOME" position first, or should it not matter ?
       
      NB - All this after precise Polar Alignment using Polemaster.
       
      Grateful for your input
       
      Many thanks
       
      Kind Regards
       
      V.
