Jupiter March 17th

Decent seeing but murky trans and very heavy dew. Only took one avi and then went Aurora Borealis hunting.

Only managed 30fps @50% Gain.

Nice one despite the dew.

Nicely done Stuart, i was at around 60%-70% gain at 35fps but thin cloud was a real pain especially on the blue runs!

Very nice , what f ? Barlow ?

That's a lovely image Stuart despite the poor trans. Did you manage to see the Aurora?

Great image Stuart - seems I'm missing the best of the season at the moment, but great to follow the action here. Nice process on this data.

One AVI but what a shot. A lovely image Stuart

Thanks guys! Didn't see the Aurora Pete we were too early by the looks of the reports.

3x Barlow with extension tube giving about f16-17 Knobby.

Hi there, your image is lovely!  Might I ask, as I've got the same camera and had my first go at Jupiter this week, how you manage to get 35fps?  What sort of exposure did you have it set to.  I'm new to this but is it the case that it's ok to have a "dark" image on the laptop due to the shorter exp times?  Or do you always need to up the gain to get a bright and detailed image on the screen?

Again, lovely image, I'd love to see what you come up with if that wasn't good seeing.

[Space Cowboy]

You need to keep the exposure histogram at 60-70% Notty.You don't want the image too dark. I usually have gain at 40-50% any higher and things get noisy with this cam. If trans is good then the frame rate can be 60-70fps as I adjust the exposure speed to get the desired histogram fill mentioned above. Of course this all depends on the focal length used.

Very interesting thanks. Which capture program are you using? I'm using ezplanetary and I don't think it's the most user friendly but it's the only one I've managed to get working with the QHY5L-iic

[Space Cowboy]

I also use EZ but would rather use fire capture though my 5 year old netbook won't run the cam at full speed. Looking to get a new one.

Very nice some excellent detail around the GRS!
