As we were getting into the swing of 'what would have happened...' the student, still plugging away at the control button, became very excited, because the telescope was finally open! We swung into action and began putting in the co-ordinates of our first choice of star object, pressed the 'move telescope' button and ...nothing happened (apart from receiving a message saying the telescope was unable to slew (move)). We tried again, and again...nothing happend. Remembering that sometime the telescope got 'stuck' and had to be given different co-ordinates to 'unstick' it, we tried entering the co-ordinates for the next object on the list. Nothing happened! :-(
There was not a lot to be done. If it doesn't work it doesn't work. We were about to begin searching for the chosen objects in the archive, when the student at the control (luckily a persistent student!) announced the telescope was working. He had entered the co-ordinates of another object on the list, and the telescope had finally responded! Yay!
With only fifteen minutes of control time left to go, I didn't think we would get many of our images, since several of them were longer exposure times. However, we managed to get two very good images of M92,a globula cluster, and the excellent Cocoon Nebula, which we'd never imaged before:

With only minutes to go, we tried to take a 3-colour picture of the Dumbell Nebula. The telescope control informed us there wasn't enough time. We reduced the time again and again, but still it wasn't possible. It suddenly occurred to me that the time was taken changing filters, so if we did a single filter it might allow this. We managed a 10s image using the red filter...which, though not spectacular, showed the nebula quite clearly!

Good for the student who kept trying...just goes to show, if you keep on trying you might just succeed!
ReplyDeleteNice pictures!
