Hi Mark;

Not bad at all. I find it a bit dark (maybe 10 to 20% longer exposures / or more gain) and a little bit too red when viewing it from my three active Macs and my Compaq PC.

I was aligning my mount on July 10th and managed to image Jupiter at 2:30 am when it was only about 10 degrees above the big hill I have out back at this new location. Nothing great, but you can see 2 moons and the broad structures of jupiter. I was shooting with 16 ms exposures and 32 fps using the Grashopper EXHAD mono camera at prime focus (2,000 mm) on the C8.

There was basically no turbulence when you were above 35° from the horizon, but any lower and you started picking up a high frequency flutter. I've only had one fairly clear night since mid june and can visually see stars down to Mag 4.5 at this location, which is another magnitude fainter than the last place. Hopefully I can try imaging without the LPR filter for DSO's, when it starts getting darker and we have more than 1 hour of darkness.

clear skies..

Hi Tim,

This is my best Jupiter to date with my C9.25 & TIS DBK 21A F04.AS &

no barlow; http://groups.yahoo.com/group/Astro_IIDC/photos/album/1777058914/pic/385697986/view?picmode=&mode=tn&order=ordinal&start=1&count=2

 Hope I`ve transmitted this right! There`s also a Saturn image with

the Flea 2 in my Planetary photos folder. Again I didn`t get around to

using a barlow & focus was a bit dodgy at this stage due to

difficulties with polar alignment (Saturn kept skipping out of shot!)

Since then I`ve used "All Star" PA successfully a couple of times but

have only done moon shots. Mark.
