These were complicated runs both in the actual imaging and the processing. 23/3/15 was i feel good seeing, but by 8.30pm dew was a massive problem. Humidity was high after all the rain the previous day. Nonetheless i pushed things further and started imaging early on to try and image the GRS before it rotated out of view. I also decided to try a 4 sequence composite (Infrared longpass/Green/Blue) which worked out excellent, instead of 3 sequences. Total frames was about 5000 for each channel. Very pleased with the detail i could get on a perfectly collimated EdgeHD 925. Best image i have taken to date.
The 24/3/15 was my first go at imaging a transit with filters. I had a very bad wind to contend with and seeing wasnt quite as good as the previous night. As a result i lost a whole RGB set for the transit start and a blue set about 50 minutes later. THe images are 50 minutes apart. WinJUPOS and wavelets destroyed the moons but i could see the detail on ganymede, so instead stacked them manually, which worked brilliantly and got exposure and colour much more accurate than after being fed through Registax and Winjupos. I then used PS to create a composite of jupiter and the separately processed moons. I think with good seeing i could get better resolving of Osiris and Galileo Regio on ganymede, but nonetheless they are quite readily visible :D.
