2021/11/04 Not an entirely successful night. Tried changing exposure settings which didn't work out too well, as well as some very thin cloud cover that drifted over. Not great.

Finally got the remote shutter cable for the Sky Adventurer mount to control the camera - now about to set the camera and leave it to work its magic… after a bit of post-processing ended up with two fairly reasonable pictures of the Milky Way from the back garden…
2021/10/03 First time setting up and trying my newly acquired Sky Adventurer tracking mount. Just a couple of images to prove that it was assembled correctly and working.
2021/09/21 Only a few worthwhile images this evening, but I did manage to get a reasonable image of Jupiter rising between the trees at the bottom of our garden, as well as the most detailed starfield image that I've been able to get with a single exposure so far.
2021/09/19 A darker evening with very little cloud. Got some clearer images looking back East as well as South West. Trying a range of different exposure lengths and find 20 seconds is pretty much the sweet spot before elongation of stars begins at around the 25 second mark.
2021/09/18 A later set of images taken around midnight Saturday/Sunday. Much clearer skies and very little cloud cover. Much more recogniseable constellations and some nice images framed by the trees in our garden.
2021/09/16 First proper time trying out various ISO speeds and exposure times. A couple of decent images including one with very light cloud cover side-lit by a late setting-sun.
2021/09/15 First time out trying my tripod mount and wide-angle lens. Just some basic tests to ensure that things are working.
