My CCD Journey : 5

Another evening with the 6SE. One of the difficulties I have had is in getting objects anywhere near focus - there are fewer stars in the field and when they are out of focus they seem to be WAY out of focus, so decided to have some fun with Vega, which is bright enough to appear on the screen anyway. Discovered that I need to give the focus knob three 'rotates' to the left (from my 32mm e/p) when it is just the CCD. Maybe I should explain that a 'rotate' is, I would guess, about 60 degrees. I

My CCD Journey : 4

Well it has been a while. Partly this is due to other new equipment that I have been 'getting to grips with'. Partly it is due to the frustration I was beginning to feel with the ccd and the seeming impossibility of me ever getting anything half-way decent. Anyway, I decided that last night would be an opportunity to have another go. Used the 6SE, as I wanted to image NGC 3242 (the ghost of Jupiter) before it completely disappears into the twilight for another year. Nice and bright, so thoug

My CCD Journey : 3

Got out again on Sunday evening. Having read the manual, I discovered a setting in the software that automatically applies a stretch to the image you see (without affecting the original data). That made quite a difference!! Focussing was a beast. The camera takes continuous images and there is a counter that goes up as you get more in focus. I was using Sirius (nice and bright). However, the counter kept changing (sometimes quite dramatically) every time it took a new shot. Well, I did the

My CCD Journey : 2

Well, I put further testing on hold for a few days as I was involved in another project. However, got out on Friday (04/03/11) with the 102. Even with the focus tube fully extended, Sirius would not come to focus. Solution: a T2 extension ring from FLO fitted between the scope and the camera. Going to go for the biggest (40mm). Even with the filter wheel fitted (when I get round to that bit) the total increased distance will be less than the range of the focusser, so I should get maximum flexibi

My CCD journey

Well, I've never done one of these before, so could be a disaster ... not that that has ever stopped me trying anything before:). Just starting with my first 'proper' ccd camera, so thought keeping a record of my experiences might be interesting, maybe even helpful to someone else embarking on the same journey. So, after the appalling conditions we have had for most of this month, I finally got out to give it an initial test run last night (24/02/11). Started off having problems getting my 102
