Hi All,
Have been suffering from withdrawal out here in "The Hill" due to the abnormal amount of cloud, storms, rain and dust over the last 18 days.
Feb 14th was my first clear night for a while and I imaged from sunset through to 2:46 am CSST, however the seeing swung between pretty crook and very ordinary and my images reflected that.
The jet stream map looked a lot better last night, Feb 15th so I did it all again.
The seeing was good enough to capture my first hi res avi in twilight at 9 pm CSST. I imaged thought to 2:31 am CSST and have put together my longest animation thus far, 5 hrs 30 mins. NOTE: Just how good the first image is in the animation, as previously mentioned this was captured at 9 pm CSST still in twilight and Mars was only 17 degrees above the horizon. I love doing astronomy out here.
I also captured some R, G & B avi's.
Following Mikes efforts on some pretty ordinary data from my last break in the clouds, I have presented a comparison of several different processing alternatives.
RGB,
RRGB, this is with another copy of the R channel used as a luminance layer.
IRRGB, This is using another IR images as a luminance layer.
R(G)B, This was rather interesting. The green channel was synthesized from the R and B channels instead of using the original G channel.
In all of these images and in R, G, B and IR there is a white spot on the very edge of the NPC. I have loaded an image into WINJUPOS and measured the location which is at approx long 42 degrees lat +60 degrees. As this spot is visible in all channels it is likely to be surface detail. I think this is the same spot Damian Peach noticed a few weeks ago and may be frost inside a crater.
Thanks for looking,
Regards
Trevor
PS: I captured 18 avi's and planned on presenting a selection of them but frankly, its way past time to get some sleep.
