Got home from work early today so had time to set up the Skywatcher just before it got dark. I wanted to get some more photos of the moon, 3 shots this time, 1/500th, 1/250th and 1/125th of a second exposure. This time the middle was the best I think.....



While framing this shot I saw a satellite "drop" by the dark part of the moon, always gives me a spooky feeling when I see things moving like that!

Compare this with a similar prime focus shot through the ETX80...the frame dimensions are identical...that means the images appear here as they would if viewed on a film strip.



After taking the photos decided to take a look at the moon with my lowest power eye piece, amazing detail - I will have to try to start finding my way around. Only problem is that even with 2 filters it still dazzles.

Just after that I got a view of what could only have been the ISS this was approx 17:45 and it was way brighter since last time I saw it (because of the work done recently by the Shuttle mission).

Just confirmed with Heavens Above that the pass was at 17:46 from West to East crossing overhead, will definitely need to get some more photos to compare with earlier in the year.

Just after this the clouds rolled in, maybe should have named the blog "cloud watching".

Another clear sky!

I had an ISS track forecast for 18:47 tonight from the WSW. So, set up the camera early but noticed the thin crescent moon that I'd missed last night was on show with a nice amount of earth shine lighting the shadow. So took a few heavily bracketted shots of this first.

Then back to the ISS, sure enough it showed right on time, the following images are variations of my second attempt to capture it on "film". This shot was made with a Canon EOS350D using a 35mm SLR equivalent focal length of 28mm, exposure was 24 seconds at f8.0, speed 800 ISO.


Only had chance for one shot, problem is that the stars etc are so faint through the viewfinder, so didn't start the exposure as soon as I could and I wasn't sure if the ISS was out of view. Next time I will try to get more shots in. The photo above is "as is" from the camera.


This version is after adjust levels in photoshop, interesting that you can now see the atmosphere in daylight. The ISS is the long streak crossing Orion. Below is the forecast plot for this pass from heavens-above, I'd say the prediction couldn't have been better!

The predicted track of the ISS is shown by the solid line running right to left with a red arrow near its' beginning. Below is an inverted version of the final image as a comparison to the chart.




This is a cropped version of the same shot, must try to get some observing done while I have the chance.
