Saturn dark spot in vgood seeing

SPX350 F32 11,216mmfl, PGRFlea3, Astrodon filters and IR742nm.

Seeing started above avg and went good to vgood and got 2 vgood sets of data with this dark blob that started to move onto disc, I could not make out what was going on until I got the red set into Regx. Storm seems to be breaking into fine spots now. Got some more dust patches on left B ring and Encke is pretty solid on right side.

Thanks, John.

Some stunning detail in those images, and spokes again on the left side. And that's one massive storm, very spectacular!

Thanks for comments.

Mark I am using a 5xPowermate which gives me F28.8 (10,080mm) - F32 (11,200mm-these images) and will take me to F34 (11,900mm) maximum.

Looks like I will be getting a few clear nights but wind may return, seeing seems best before culmination but everytime cloud passes it takes 20mins for good seeing to return so need a completely clear sky really.

Thanks again for comments.

Great shots there, John. Pushing the FL pretty high, although that sky down there must be like crystal.

Oh God! I captured the same spot on the 15th and thought a moon was transiting at the same time. I feel foolish. But, my resolution is not that great at f25 8" SCT. That is really cool. So, what is the dark spot? Another kind of storm? Any theories? I'll be glad to post my series if anyone is interested.

Thanks again, that spot was the oddest thing but the IR filter helped show it but F34 (actually F34.2) does help give a good size. I would like to try longer FL but don't quite know how to get there.

Welcome Paul, many have struggled with seeing recently but any image of Saturn atm is a document of an unprecedented storm event, not sure what the dark spot is though? You are welcome to post your efforts here.

Regards, John.

The pinnacle of planetary imaging is when you can capture during fantastic seeing something that others have not done before. If you can control all the equipment and relevant issues; then the only thing left is the seeing. You have taken advantage of the seing and produced a fantastic set of images.
