24th Feb Titan + shadow transit

Hi all,

Imaged the Titan shadow + Titan transit every 10 min's from 11:30 UTC to 16:10 UTC.

I am working on a 28 frame animation covering 4 hrs 40 mins of the transits

This is an RGB from 12:25 UTC.
The seeing was variable between 7 - 8/10, for about the first hour there was some high altitude Cirrus that acted as a filter, thus the first few images are dimmer than they should be, can still see Titan & shadow though.

It will take a couple of days to process all of my data, I have 46 avi files overall.

I concentrated on R channel images and have some excellent detail in them.

All of my R channel images were captures of 1700 to 2000 frames;

exp 1/27 th sec
frame rate 30 fps
Gn 880
Gama 140
Hist 200

The files for my RGB images were all captures of 875 frames for each channel. R & G channels;

exp 1/27 th sec
frame rate 30 fps
Gn 880
Gama 140
Hist 200

For the B channel

exp 1/27 th sec
frame rate 30 fps
Gn 1023
Gama 140
Hist 200.

Will post more as I work through my data, the 4 hr 40 min animation should look good.

PS: Also found a possible storm.

Thanks for looking
Regards
Trevor
