It was a beautiful clear Moonless night last night (we don’t get very many of those in a year) and instead of imaging I was setting up 🙁 These things unfortunately need to be done, shame it was under almost perfect conditions though. Never mind. So I was working on the two Canon 200mm lenses and their Trius M26C cameras last night. Both lenses are now aligned with the Sky 90s so everything on the megawasp array is pointing to exactly the same point in space – great. Next was focus training. Tom How not only built a second autofocuser unit for the second 200mm lens, he also swapped out the original stepper motor I had for one with much finer steps. The result is that I now get great V-curves from both lenses and I only now need to click on “Focus” in FocusMax for both lenses to come to a very good focus. Excellent!! So the last job to do is to flatten the new Trius M26C to the optical train using CCDInspector. It’s now 12:30 a.m. CCDInspector running, camera downloading images for inspection – yes it is a little bit out (the other 200mm lens and M26C is almost perfectly flattened) so I just need the Allen keys to adjust the second camera. I can’t see them. They aren’t where I usually leave them. There’s been a big tidy up in the observatory especially as there is now yet another computer in there (making 5 in all) and I know I put them somewhere safe and obvious – but I can’t see them. O.K. it’s 1:00 a.m. now and I’m just going to break something if I carry on, so I shut down for the night and come indoors. Brushing my teeth before bed, of course, I remember where the Allen keys are – I put them in a clear plastic bag and stuck them to the side of the pier where they would be obvious!! Go out this morning and check – yep of course that’s where they are. Very annoying I didn’t get EVERYTHING set up and ready to go for the next rare, clear, night – but that’s the nature of this game. Pure frustration and annoyance for 360 nights of the year for the joy of 5 nights of great imaging.
