A night of good seeing.

 

Jupiter displays a wealth of features, particularly the merging SSTB ovals seen here setting, Saturn with a couple bright spots in the polar region (evident in all subframes although very hard to see here) and of course Mars, at 14.7" with Syrtis Major prominent.

 

Thanks for looking

One of the best results I've ever seen with such size of telescope!

Thank you everybody. For these captures, Jupiter was at 39 degress whereas Mars and Saturn at 32 & 31 respectively. The seeing was fair with moments of good (this is about as good as I get for this location) and this was an all-night session. Very enjoyable to observe the major planets with comfortable temperatures and good conditions! 

 

I have more data but as always they will show up later down the line.

The C9,25 is a very capable mid-size planetary telescope. This is my 2nd such OTA and visually when the seeing is good the views are amazing! Under excellent seeing I have had incredible results on Jupiter and Mars during the '16 apparitions. I only wonder what it would produce with the planets in Australian or Caribbean seeing/altitudes!

Correction: The SSTB ovals are NOT in this data set. I have them registered on previous data which I will upload tomorrow!

Particularily good with superb color rendition, especially Mars.

Excellent work. I especially love your Mars image.

Do you have any capture details you can share, in terms of video length, percent stacked, WinJupos or not?

Thanks for any advice you can share.

Thanks for any advice you can share.

Jupiter: 60sec videos, approx 128fps, 25% stacked. Derotation 12 minutes.

Saturn: 120sec videos, approx 100fps, 15% stacked. Derotation 4 minutes.

Mars: 90sec videos, approx 200fps, 25% stacked. Derotation 16 minutes.

 

I typically use Firecapture in autorun mode and record series of videos ideally approx 2 hours centered on the transit time of each object. I do this because a) My local seeing is never consistent enough to allow me to choose when to capture. This provides me with a good window of opportunity to catch better seeing even if I'm not glued on the monitor, and b) I really enjoy producing animations from the resulting stacks. Then I use autostakkert batch mode to process the resulting videos accordingly and go through them in Registax with the same wavelet scheme to isolate areas of better seeing. Once those areas are found I might re-stack them with stricter percentage and slightly different wavelet schemes. Then, winjupos to derotate and back to registax for additional wavelet sharpening (very mild, typically only 1 &2 sliders on this stage). Finally, photoshop to correct color balance/saturation and levels adjustments.

Agapios, excellent image set! Mars is my favorite of these 3. Details look great all around. Congratulations on these

Hi Agapios,

 

They are all great!

 

Yes, I can see twin storms on Saturn as well.

 

The SPC is so large on Mars that it extends all the way up to and possibly into the very southern edge of the Hellas Asteroid Impact Basin, I don't recall this occurring before.

 

Speaking of Hellas, it does not look right this season. The CO2 glaciers inside of it should be reflecting sunlight and they are not. Your image shows that it is neither filled with clouds nor fog, so maybe it is dust that is obscuring the sun's light from reflecting off of these glaciers?

 

They need to redirect the HST in order to see what's going on up there.

 

Best Wishes, Dan cool.gif

Hi Dan, Mars has passed it southern spring equinox (May 22nd) so Hellas has been free from ice and fog for many weeks already and it's normal :)

The edge of winter SPC is extending onto Hellas every martian year. This year thanks to the season and the geometric viewing from Earth, wee see it clearly.
