IMO & IME, photographs can be misleading - usually are - when used to show what an observer will see through the eyepiece. Definitely apples and oranges. I prefer oranges.

Well yes, that's pretty much a given I would hope for anyone who's been observing for any length of time.

Yes, you are right. The photos don't show the seeing and are much larger. The colour is weaker in the eyepiece. With good seeing you can see more details but you need time to catch most details in the eye piece on a smaller Jupiter. I added a link to the video. The video is quite large to show the details in youtube. The view in the eye piece was much smaller but somehow nicer than in the youtube video and the oval group in the STB was very hard. There was just something irregular that was brighter than the STB. It can be seen in the video, too but the time when it showed details was too short for me to see the 3 spot group clearly. With the camera you can use the short time with good seeing of this area for the stacked sum picture. At least I could see some festoons for sure and the brighter band between GRS and the SEB.

Alex did a nice sketch at a similar time with his Zeiss AS 80/1200:

Hi Alex, if I should take your picture out of the thread, I'll do it but I think it's nice to see a sketch of a 80/1200 refractor in addition to the youtube video and to the picture.
Clear skies,

Beautiful, Roland!

Thank you very much

There are some fantastic images here given the apertures used. I thought I'd share a hand held afocal shot I got using a Stellarvue SV80ED from earlier this evening. I was using a Sony Cyber-shot set to video over a 2.5 barlowed 6.5mm Meade HD-60 eyepiece. Processed using RegiStax 6.1. Not as good as some of the shots presented earlier but I'm pretty happy with it for being a hand held shot.

Those are indeed fine images Niklo with the small aperture used!

Jupiter is still being quite nice in small telescopes. Here is a quick 10 minutes sketch from this night (the sketch is too raw as it is directly from the eyepiece, unfortunately I'm not able to catch all those levels of grey that were visible at the eyepiece):



I could not use too high magnification because of bad transparency which was making Jupiter too dim at higher magnifications. Still the seeing and view was very nice. I had to stop sketching shortly after just 10 minutes, Jupiter went too dark. Still, it was quite refreshing view and I'm glad I took the telescope out even for those 10 minutes.

Just for fun I was using vintage 15mm Zeiss ortho which was providing me with right balance between magnification and Jupiter brightness. Sharpness and contrast was very nice, I did not have a feeling that I'm loosing anything with respect to modern eyepiece (but this was just from memory, I did not make a direct comparison for example with my TMB Monocentric 16mm, may be next time when the weather is more stable).

Can we see some updated pics on what Jupiter looks like through an 80mm APO in the eye piece? No zoomed in pics please, I’m trying to get an idea of what you actually see in the eye piece.
