Hello,
Well, after a somewhat slow start, here is my 1st serious Jupiter for the 2008 season! The jet stream map looked full of promise although the surface winds were quite strong, knocking Jupiter off the DBK chip on 2 out of every 3 AVI’s, so it was more like a war of attrition than a relaxed imaging session.
I decided to go for broke and cracked open the seals on the C9.25 and TeleVue x4 PowerMate and almost got away with it. The final image is a little soft as the pesky surface wind gusts took the edge of what looked like some quite steady jet stream conditions.
This is from probably the best AVI of the session. Brisbane, 22nd Sept 2008, 19:23pm AEST (GMT+10).
- Celestron C9.25 F10 SCT.
- TeleVue x4 PowerMate (2”).
- DBK21AF04.AS CCD camera.
- Gain=850
- Exposure=1/15 sec.
- Frame rate=15fps
- Gamma=10 (hard left slider)
Cheers
Dennis
