Jupiter, Saturn, Mars Planet Parade with Animation: Mak127/NexStar SLT

Recommended Posts

Hi,

using my wacky NexStar SLT and Celestron Mak127 is often frustrating, but when hunting planets it can be rewarding to overcome the limitations.

The images are done with a ASI120MC and Firecapture. Used a 3x Barlow.

Processed in AS!2, sharpened in Registax, touchups/GIF in GIMP 2.9.x.

Cheers,
Carsten

I just made a comparison of calculated (JuPos) and my imaged Mars. Yea! Not only smudge on the lens or stacking artifacts :-)

Happy Carsten.

PS: The lower one does not fit exactly, messed with the date in JuPos.

That's quite a nice set of planets from the 127 Carsten. You're getting some good detail coming through, nice work.

Stunning images with your ASI120MC.

I have a Celestron 127 SLT and haven't had much success imaging with my Sony A5000 camera and Celestron 8-24 mm zoom EP. Which EP did you use? Was it difficult to focus with the 3x Barlow?

I used a ASI120MC which is mounted focal, so no eyepiece. Same for my DSLR. With the 3x barlow I get 4500mm focal length and the small chip on the ASI120MC makes a small field of view, so much pixels for the whole planet disk.

Focussing is always a pain especially when the seeing is bad. So you often need to do a test and change it slightly. I use a motorized focusser which is controlled via bluetooth, a very nice thing for that high focal length.

Cheers,
Carsten

Thanks for the info, Carsten. Your terrific images are most encouraging about what is possible with this scope.

Is there much difference between the ASI120MC and the NexImage 5?

Hmm. Just did a quick look and if I am not wrong this camera is more a still camera? Video resolution 640x480? Not sure. At least I think the ASI is more versatile, also usable as guide camera and even for a bit Deep Sky... But maybe better ask in a video imager board :-) Of course you will get maaaaany opinions ...

I'll do a bit more research (and take more photos with my Sony A5000 and see if I can improve the quality). Thanks.

      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.

      Yesterday I managed to climb out of bed at a little past 3:30AM to get my small portable rig out to a small nearby park and setup to observe Jupiter, Saturn and Mars. I got the Skywatcher Evostar 72ED DS-Pro last summer so I was especially excited to see how it would perform on Mars because of its red wavelengths which many small fracs often have trouble with handling.
      At first it was partly cloudy but I persisted and was out and setup on the field at around 4AM. The sky was already surprisingly bright here in Denmark but Jupiter was shining bright and Saturn faintly visible almost right besides Jupiter. Fortunately for me it wasn't too cold, but I was happy I brought some gloves anyways;)

      This picture was taken at 5AM while I was observing Mars.
      I remember from last year that my scope didn't perform great on Jupiter for some reason, and the view of the gas giant wasn't anything different this time either. Using my 4.7mm ES 82 degree eyepiece not much detail visible except the two main bands and its moons. I would later return to Jupiter after the scope had cooled down a little and the view was perhaps a little sharper.
      Pointing the scope at Saturn, which I was very satisfied with last year, I was amazed of the detail the small scope managed to squeeze out. It doesn't compare to the view I had last year with my 10" dob under great conditions at 255X but I was able to easily spot surface banding on the planet itself, and the Cassini division was also surprisingly stable. I really enjoy the stable and consistent view through the small refractor! I observed Saturn for quite a while until I eventually set out to try to find Mars. At this point I couldn't even see Saturn with the naked eye but I was fortunate that Saturn and Mars were approximately the same elevation above the horizon.
      After a few sweeps across where I though Mars would be I finally located the small red speckle, this time with my 6.7mm eyepiece so I had a larger FOV. Switching to the 4.7mm, though still very small, I was surprised that I could pick up a dark surface marking across the disk on the lower southern half of the disk. Furthermore, the southern polar cap was really pronounced and you couldn't miss it. I watched Mars drift through the FOV until about 30 minutes after sunrise where the contrast between the planet and the sky became too low and the dew started to set on the lens element.
      Using my small refractor for observing the planets I have always wanted to magnify things a little bit more, and I think the telescope would have no problem doing so. A Nagler zoom 3-6mm has been on my wish-list for a couple of years now, but the upcoming planet season really makes me want to find one second hand
      Here's a video I've made that covers what I've written above with some footage I tried capturing through the eyepiece:
      I hope everyone on here is still doing well despite the current situation!
      Clear skies!
      Victor
