Mare Australe - The SAC4.2 shakedown continues

Mare Australe from 05-10-06

Seeing not good: 2-3/10
Transparency: 7/10 (halo around the moon out to about 1.5 lunar diameters)

Still battling the colour cast though it is much easier now with the UV/IR filter. Though as you can see from the unadjusted colour image of Tycho there is still a predominant pink cast to images. Hopefully I'll have it sorted out by Saturn time

The images of Mare Australe have all been processed through Registax without using the colour option, so they have ended up greyscale. The first images is a ROI capture (Region of Interest). Catch-42 lets you select just the area you want to capture. This significantly speeds up the frame rate (15 fps), which for this little camera is important as it captures RAW with no compression. Compare the second image that used no ROI (6 fps). Exposures varied between 10 and 25 ms with gain around 60 - 80%

The fourth image is the same as the third one but using different processing. Pick you fav.

They are no Mick Salway, Zac Pujic or Dennis Simmons, but I'm happy with the progress of this little camera so far. I've deliberately avoided doing a side by side with the ToUcam at stage. I'll wait untill I feel confident with the SAC first (and the image size of this chip still blows me away for a planetary camera. None of the images have been resized from the originals so override windows automatic resizing with the "Expand to regular size" button and check out how bit they are compared to the ToUcam chip images we normally see)
