Jupiter 08/03/2014

It seems ages since I have managed to produce a planetary image so I was determined to press on last night, even if the seeing and wind were against me.  I tried to give the collimation a tweak as is my usual routine but the star test was so bad I could not tell if the scope was in collimation or way out of collimation.  I just left it as it was.

One advantage of the night was there was no dewing problems what so ever, everything remained bone dry.  It is not often I get to use the C14 with no dew shield or heater and get away with it.

This is the image I managed in the end, nothing special but about as good as I could expect with the conditions.

Nice going Chris despite the poor seeing - struggled with my own star tests last night and was definitely making things worse. Wish I could get some raw data like your video

Very nice indeed!

Thanks for your comments guys.  I think the reduced size of the video playback makes it look better, though that was the best capture of the night.  Lots of 12 minute captures with 640 x 480 frames and 111 frames per second very quickly fill up a hard drive!

Cheers,

Intresting Chris, conditions are against us but the avi seems much the same view that ive been getting over the same period, but correct collimation I understand is quite difficult on the c14? & are you using any cooling method on your scope ie fans etc!

I'd not complain too much about that myself, Chris

I use a Lymax SCT cooler for initial cool down and occasionally between imaging runs.  In my experience C14s definately need some form of cooling to get anything half decent out of them.  I will soon be fitting 4 fans (when they are delivered) that will be able to continuously run while imaging, though that will require disassembling the scope and drilling holes for them.  I am not looking forward to that!

Great image despite the conditions!
