That`s great Milton,

Sounds like your light pollution woes might have abated somewhat, now you`ve just got your Calgary weather to contend with! I`ve moved my scope onto some bricks on the grass next to the new carport (which has replaced the old position on the concrete slab) but the ground still hasn`t dried up & is muddy. No sooner does it begin to dry a little & back comes the rain! There`s a chance my brother might come for a holiday & make me a small pad for the scope (along with an access path to the front door) beside the carport. I might sneak it in on this pretext! Have you been able to do anything yet about Hyperstar for your C8? It`s unavailable I understand because of the basic design on the C9.25. That Jupiter shot`s quite an old one-with the Saturn one I still had a significant space between scope & monitor & couldn`t see readily to focus. I may have to take the Mac Mini outside as per your advice in future as my Bluestar adapter will only go less than 8 feet! I did download The Sky X & also have Sky Tools 3 Pro & a 2nd hand pc ( it wouldn`t completely function on Virtual PC). The Lenovo is being worked on by another brother-needed restore discs. I`m hoping Greg Crinklaw will be able to provide configuration details for the Flea 2 (based on the Manual & spectral sensitivity graph) which will enable ST 3`s exposure read outs!?

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/

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.
