Guest Posted July 23, 2016 Share Posted July 23, 2016 Now let me be completely honest here! I honestly don't know which are moons and which are background stars. I'm 90% sure I've got Titan. The images are: All were taken using a 1540mm Mak and DSLR at ISO 6400. The first shot was 1 second exposure and shows some trailing. The second and third are 1/2 second exposure. I took multiple frames and stacked them. I would be REALLY interested if anyone has taken any driven exposures, especially with an exceptional mount.

Smithysteve Posted July 24, 2016 Share Posted July 24, 2016 Hi Phil, trying to work out the position of the moons etc... ? what night or date and what time did you take the last shot? also was your view inverted north to south, left to right or both? cheers!

You have too much time on your hands Steve. I was about to post the same thing as I like a little challenge. But I can make another cuppa now and carry on relaxing and reading my book. Will be interested to find out what is where in that pic. Thanks Steve. Link to comment Share on other sites More sharing options...
Guest Posted July 24, 2016 Share Posted July 24, 2016 OK, the images were not inverted. The first two images were July 18th 2200 GMT. The third was July 17th, 2000 GMT, I wasn't sure of the exact times of capture, as I took several photos in both sessions and only recorded the times I went out.

Smithysteve Posted July 25, 2016 Share Posted July 25, 2016 The exact times that the images were taken are a bit ambiguous Phil, but I have had a go... The brightness of Saturn drowns out a few of its closest moons! But taking Titan pretty much for granted and allowing for the magnitudes of the moons, this is my best guess... For example Hyperion is a miserable mag+15.1, whilst Rhea is 10.3! And I could be wrong. But I would welcome any further comments on this...

Guest Posted July 26, 2016 Share Posted July 26, 2016 Thanks, Steve. I'm amazed I'm getting down to Mag 15! Link to comment Share on other sites More sharing options...
