Truly splendid Geof 👍🏻

Thanks Jeremy

Thanks Kon, yes possibly the best of the night, though I have 2 later runs that I need to process, with Mars at an even higher altitude, but through thickening haze. I included the earlier two images here, as they show the Tharsis Montes a bit better, well more prominently that is.

All hail to the mighty C14! Excellent images, Geof. Mars is really putting on a show and the best is yet to come!

Reggie

Thanks Reggie, yes, fingers crossed that we get good seeing over the next few weeks...🤞

They are excellent! Makes me get an itchy trigger finger, regarding a dedicated camera, even though I only have a C9.25.

Lovely Geof the big C14 showings its resolution in bucket loads. 

Thanks both, Mars is definitely begining to put on a show, hopefully with still better to come, though it doesn't get much bigger this apparition.

I had fairly good seeing last night for long runs on both Jupiter and Mars. Unfortunately, whilst the seeing was good, transparancy was changeable, with lots of passing low haze/fog, requiring constant gain adjustments to balance the histogram. Everything, was pretty drenched by the end of the session. Nevertheless, it was an enjoyable session, with the below 3 images from the better of the Mars runs. Each is best 30% of a 6 min SER (75k frames) at 5ms (200fps), captured with the ASI462MC through the C14, with an ADC in train.

Mars was at altidudes of 45° through 52° for these 3 captures. It is now displaying a 15" disc, with some good detail starting to come through. Olympus Mons is clearly seen, with the line of 3 shield volcanoes known as Tharsis Montes, just rotating towards the night time terminator.

Thanks for looking.

Excellent capture and processing.

Another Jupiter, probably my best of this apparition, captured on 14 Oct 2022, from Norfolk UK, latitude 52° 30' 27". C14XLT, ASI462MC, ADC. 3x6 min SERS captured at 8ms/125fps with FireCapture, then processed in PIPP, AS3!, Registax, WinJupos and Affinity Photo. Total of 22 mins de-rotation.

Wow, those are superb Nigella. The ones after you cleared the trees are absolutely stunning.

Thanks, I missed the double transit on 26/10 as I was travelling, so fingers crossed for that I have clear skies for this event...🤞

Btw registax designer is working on a new wavelets program. And is considering ideas to sharpen Mars while limiting edge rind. Right up our street sure you agree 

That will be great to see. I didn't know the Registax designer was even still actively developing, as I hadn't seen any version changes in many years.....🤷‍♂️

Oh yes, that is one gorgeous Mars Neil. A great capture and even better processing IMHO.

Excellent annimation. It's good to see what I missed 😉

Both good captures Pete.

Really nice capture and processing Kon. I missed this double transit as I was away from home in the Cotswolds since Saturday.. I got back home this afternoon, so hopefully will get some more imaging opportunities over the coming weeks.

Brilliant images Neil.

Superb capture, one of the best i have seen so far this year.

Thanks Pete

Given how the weather is in the UK, you certainly cannot afford to only image when the Jetstream is out of the way. I always feel a little more confident when it is not present, but as your image shows it is certainly possible to produce fine images with it over the country.

Thanks Pete, yes, if it’s clear in the U.K. then it’s a go, Jetstream or not 

That's lovely, very nicely processed, a natural look with lots of detail coming through.

That's very good, the dark regions of Sinus Sabaeus and Sinus Meridiani are well seen to the left, with Syrtis Major to the right.

It might be and seems to fit the description. But i also notice focus was good and stable. A lot of the time its been constantly coming and going. But not so on this night

I don't know, I'm just speculating, but I wonder whether the focus shifting is due to vertical layers in the atmoshere mixing, causing an oscillating (up/down) lens effect, something that a steady fast flowing air stream might not do, or do much less, so consistent focus is more accessible.....🤷‍♂️🤔

Very good

Ok its good discussion as i don't totally understand it myself. Here is a 1000 frame section at the start of the film up top. which was one of the calmer ones. Had to save as AVI because SER for some reason keeps converting to 50 FPS  and it affects the appearance. The capture has 200 frames per second and avi portrays that accurately. Will have to watch on reduced size window on your chosen avi player. or you won't be able to see correctly (it will be huge)  Just not full screen is what i mean. or the image will be resized to fit. 

You can clearly see what looks like a fast jet stream running from left to right. No jet stream was on the map that night, and another member reported good seeing. There is good detail under the air stream as can be seen on the capture and finished image I've posted. My best guess is either a jet stream or heat from house rooftops but i am unsure. What's also interesting is although the problem is quite bad the result still looks quite good. Suggesting either the effect isn't as damaging as what it might appear. or my processing technique is helping cope with it. Or a little of both??.

Thanks Neil, I have of course seen that effect, but never really paid much attention to the direction of the flow, so thanks for drawing my attention to it. I do wonder if that represents what I've referred to as 'laminar flow' in other discussions, i.e., smooth, not turbulent air flow, hence allowing detail to come through, despite the fast moving stream... 🤔🤷‍♂️

It's a odd night i can show examples if anyone's interested how bad an air flow going from left to right is on these images.

Hi Neil, yes, please show what you're seeing plus how you identify/assess that effect, it will be very educational.

Looking good Neil. It seems that maybe the dust storm is settling, allowing a bit more detail in and around Hellas....?🤔
