I've been doing astronomy for 47 years, so I am probably not giving it up any time soon.

Astronomy has changed and over time my interests have evolved from planetary observing, into meteors, through variable stars and, finally, to the deep sky. These days I'm especially interested in imaging of various sorts and find making pretty pictures increasingly dull. Its just not a challenge anymore - todays's kit pretty much does it for you. 

I generally use a 250mm f4.3 Newtonian on an EQ6 and Starlight SX694 camera from a site in Wiltshire near the Dorset border where the sky is mag 21. I also have sporadic access to a Celestron 11" RASA.

Fortunately, given the UK weather, I like programming and so write my own MS VB6 code to run a Starlight camera and interface it with TheSkyX software. Its a worthwhile skill for when I finally retire and get the chance to observe more - I want to make the most out of every night.

My current software project is writing code to automatically locate asteroid/NEO trails on large field of view imagery, while my observing interest is in seeing how far a 250mm can be pushed and satellite imaging.

I've been messing about with a Paramount MEII recently. I got it set up and TPoint  set up (error distribution odd but around 140arc sec RMS - mount advising no further tweaking) and then found that following updating to a daily build that it couldn't find a thing - literally. It didn't even get its "Home" site right.

Solution was to nuke the TheSkyX Pro build and go back a year or two to an older build and start again. Working my way forward, but worried about installing an update that breaks it again - lost 3 nights sorting it out last time.

Anyone else encountered this sort of problem?

Reply from Richard Miles: Later this year I shall be tackling the same task so your warning should be a useful one!

Three simple images created with a decent Starlight camera, a GRB Griturn lens adaptor, a Nikon 20mm lens and a tripod. Unlike some lenses I can think of, the Nikon lens I had borrowed did not totally lose the plot with very red stars and focus was quite easy really. Went for a series of 3s frames and after stacking the images had to crop them a tad because of field rotation.

Have given the lens back but will keep an eye out for one, kinda, sorta.

Managed to get outside for the first time in a while - I seem to spend my spare time sorting out stuff/writing code for work or doing things around the house. Ah well, at least its warm indoors. The night of the 4th-5th Jan 2017 was -5.5C - though didn't feel too bad as the wind was very light. Moon was around until around midnight (which was a pain) and I didn't start until 21:00, but I did sneak in V900 Mon, Hinds Variable Nebula and McNeils/M78. Finally gave in at 02:05 when even industrial grade coffee and Black Sabbath, Pink Floyd and Rammstein wasn't keeping me alert. 

On Boxing Day night I had a go at a mag 20.7 asteroid, but failed as I misidentified the field of view. Ho hum. That's 2hours wasted then. A useful reminder to always have a good quality Skyview printout to hand. Shame to waste a night but at least I spent time under the night sky again.
