First Jupiter - 15th Sep.

Sorry for another "first Jupiter" post - I suppose this is what happens when we get our first major break in the clouds!

I used my Explorer 150p and SPC900 with a 3x Tal and extension tube (my Skywatcher 2x barlow tube which I had dropped - oops).

I'm pretty happy with it for a first attempt. I did hope to see the GRS in there as Stellarium shows it had just come fully into view, but the detail level must not be good enough. There was a thin layer of high cloud at the time though, so I'll have to try again :(

All criticism gratefully received.

You mustn't apologise for posting images, besides, it's a perfectly fine example. Lots of detail showing, and the banding colours look great. Not sure about the GRS, perhaps Stellarium got it wrong.

Are your location details set right in the programme?

Thanks very much chaps!

Yes, spot on, I've just double checked.

My Stellarium runs an hour ahead so its easy to be deceived by GRS times.

Maybe it comes down to daylight savings then? I assumed Stellarium altered this automatically as I couldn't see an option to select it, but maybe it doesn't.

Newbie question: 3x Tal is a 3x Barlow?

Yes, that's correct. It's great quality at a low price. :(

I do wonder if the focus could be better as it is quite difficult to get spot on on a laptop screen at this low resolution. To that end I'm going to order a bahtinov mask next week.

Thanks guys :(

neil, I have been in awe of your Jupiter images over the last few days. I am constantly worried whether I have collimated correctly. Can I just ask, in your opinion, would I be getting detail like this if my collimation was out? Or should I be getting more detail? Cheers.
