Sunlight via Jupiter and Saturn

Post by MapleRidge »

Hi everyone...

I was clouded out most of Friday, but spent a few hours at the scope on Thursday night trying to remember how to image the planets. A previous night was a waste but managed to refine the settings to get some decent shots of Jupiter and Saturn. All are through the C14 with the ASI290MM camera.

The images below of Jupiter are a RGB composite through Astrodon RGB filters and the mono shot is an IR 680nm pass filter:

Saturn was a secondary target and I imaged it before I closed up the observatory, and this is another IR680nm filtered image.

Each is a stack of the best 200 frames out of 1,000 frame video clips, processed with AstrImage or ImPGG.

I'm looking forward to many nights of imaging Jupiter in the coming months.

Thank you Brian.
The C14 certainly has shown to be a good scope for these two captures. :bow
Saturn is my favourite. :hamster:

Can you confirm if/what Barlows and filters were used for the session - please ?? :?:

My likkle 80ED tried the best it could with the 2.5X and 5X Barlows, but nothing anywhere near as good as yours...
(maybe putting both of those together = 7.5X could be tried, but unlikely the tracking or seeing would cooperate)..

Thanks for sharing
Terry

Thanks Terry, appreciate the feedback.

All of the pics were taken at the prime focus of the C14 (3,900mm) with the ASI290MM camera (2.9u pixels). The colour image is a composite through separate Astrodon R,G,B brand filters and the IR used Baader 680nm pass filter. I do have some images taken through a 850nm IR-pass as well as methane band-pass (889nm, 18nm FWHM), but haven't made it that far in processing. The Methane is a challenge with seeing as individual exposures are 2-3 seconds long and need to try to capture enough to stack a decent image before rotation of the disk moves the features. There are ways to deal with this too...just more image processing :shock: With exposures over 1 sec, the ability too 'freeze' seeing with short exposures is a lost cause ;)

Thank you Brian for the very useful details provided, which all makes sense.

Even though I have all the necessary filters, my own captures were taken over a very short space of time (purely as a basic trial of the new scope) and due to the 20-deg/elevation of both Saturn and Jupiter where a house-obstruction and a newly-planted tree in a neighbouring property prevented more time than would have been useful.
That tree itself has grown in a year to over 30-feet and although quite narrow at present, will inevitably expand side-ways over the next years.
Unnecessary planting, but short of me using my chain-saw, will no doubt prevent much imaging future...

The new mini-observatory elsewhere in my large-garden, may help somewhat...

Best Wishes
Terry

Brian, it turned out great considering the complexity of the shooting rapidly rotating planets with monochrome cameras with filters. You may have heard about derotation in WinJUPOS. It can further enhance your already great shots.

Thanks for your feedback Ivan!!!

I use WinJUPOS for de-rotating, but need to refresh my memory to use it. I have a few long long SER files to try when I get time to work on it.

Wow!! these are fabulous :bow :hamster:

I've never understood Winjupos and never found a decent tutorial either, it seems it is a dark art for the elite ;)

Thanks Alexandra :bow

I got the scope much better collimated with a Tri-Bahtinov mask last week and it made quite a difference. I like the mask as it is less subjective as doing it by eye...the spike is either in the center or it isn't :lol:

WinJUPOS takes some getting used to, but once you get it figured out it isn't bad to work with. There was an online tutorial that I need to fond before I try using it this year.
