Nope it is dust:laugh:.As for the MP I'm setting up the Observatory to work with ACP.Should have it done in time for the Very dark nights

Great stuff Carl,
Its great to see Jupiter coming back up once again.

Nice image - I have a question (to all or any) what sort of integration times are recommended for Jupiter?. Carl your image is good - I get cloud bands and no detail. This could be that I'm not capturing any detail but I think also I'm going too long on the integration times and as planet rotates quite fast I suspect that whatever detail I get is getting smeared out.

I take around 50 sec on each channel RG and B. at 30 frames per second. I think your problem is collimation of your scope that why your not getting any detail. What scope are you using and camera.have a look at the links below.

Hi Carl.
Nice work,
great to see Jupiter back again..
here's to more great images...

Thanks Carl

I have come to the same conclusion regards collimation of my scope. I've been suspecting that that is a contributing factor.
My scope is an 8" Newt - have it 11 months now and only attempted collimation in past week (never done that before - too "scary" ). Not 100% confident yet on process but I'll get there. Using cheshire and looking for nested concentric circles on defocused star. problem is I always see nicely concentric circles on defocused stars - I'm thinking of changing my brand of cheese.

Look forward to seeing if situation is improved as result.

I have a habit of grabbing too much data hence tending to long (minutes) integration time - so your response is helpful.

Jupiter - while not only prominent - is apparently in good orientation for various mutual moon eclipses/occultations in coming weeks so I hope to follow your example and revisit Jupiter.

Regards

Mark
