Jupiter 22 may

[Lester]

Hi all, this is my second attempt at Jupiter for the year and got a slight improvement on the last. Jetstream was present, but conditions were very calm.

Well done Lester,

Look forward to seeing more of your work.

Thanks Trevor. Here is the last avi processed with a slight improvement in contrast. Usually my practice is to capture each colour for 45 seconds, but this one I tried 1 minute per filter.

Hi Lester,

The jetstream can put a real downer on imaging, for sure.
The last couple of times that I have imaged, the GFS charts have looked pretty crook but the seeing has not been to bad.

Not sure about how reliable they are, I suppose if it is clear than it is always worth a try to get some data, regardless of the jetstream predictions.

With Jup I always go with 45 sec's per channel. I reckon it takes about 10 sec's for me to rotate my manual filter wheel, so I get my 3 channels in under 3 min's.

Cheers
Trevor

Thanks for the info Trevor. As my conditions improve, I think I will need to use 45 seconds per colour also. I am using a manual filter wheel.
