Jupiter 2nd Oct

[neil phillips]

Seeing was better than the other day. Still not great but certainly a lot better. trans was good. Just kept going out of focus. Though there was enough moments at the end for some detail to come through

Wonderful Neil 

[Pete Presland]

Looks really good Neil, plenty of very nice detail visible right across the disc.

[Kon]

Great result there, and the shadow in nice display. Lovely details considering the conditions. Seeing became pretty good, on/off, around 11-1230.

[Adam1234]

Very nice

[chiltonstar]

Nice.

With my 180 Mak last night, I found there was a lot more shadow detail on the disk than I normally see - transparency maybe as the Milky Way was very bright and clear with the naked eye. I always think it looks weird when the moon shadow is "on the wrong side" after opposition.

Thanks for the positive comments, guys.

Yes it started wobbly. But improved as it got higher. Still not the best here though as it was going in and out of focus. If  I could just get a run where focus was solid. Even better would happen. But those conditions are much rarer here. Still i will take the improvement i had from the day before

After the day before transparency was a lot better. Seeing also somewhat better i thought Chris. Though focus was difficult. I would get it close. then tweak one more time for precise focus. And it would go out again. I've seen this effect a lot recently.

Interesting that the disc, as opposed to the shadow, of Io is difficult to make out while near the centre of the Jovian disc, whereas in the case of Ganymede, you can make out the disc quite easily throughout.

I've seen it a lot over the years I believe it's a contrast effect. Just saw a C14 shot of the moon appearing exactly the same 

[Ibbo!]

Good result.

I had the same here regarding seeing and have yet to stack my data.

[geoflewis]

Excellent result Neil. As you know I was out last night with my C14, still processing the data. I had trouble with Io in post, which as you commented is likely due to contrast effects. I've had better results with Io using an old TIS colour camera previously, so got sidetracked wondering what the heck....

I'll get my processed later and put it up in a separate thread. As you also observed the seeing was very in/out with focus changing rapidly minute to minute, so in the end I went with what was something of a gut feel on best focus. We really need to have a session with more stable seeing to nail the result.

Look forward to seeing your result. Should be nice. There were moments of good focus around the country it appears

[chiltonstar]

If it is a contrast effect  it looks much the same in my tiddly scope (apologies for the processing, my skills are limited).

Yes, and it's better to have it around opposition. But I am not that hopeful. But stubborn enough to try

look forward to seeing your finished results Geoff

I expect it to look the same in most images Chris. Though of course you never know I suppose

Good capture
