It was a nice summer night, so I set up on the front porch in Oshawa and tried my hand at some solo CCD imaging. There were a couple of street lights that were bothersome, but I was set up in
front of the house for maximum convenience, not for dark skies. My goal was to keep things as simple as possible -- minimal polar alignment, no commuting, no guiding, and minimal image
processing.
I was using the Starlight Xpress MX512, a 12-bit B&W CCD camera. As I soon discovered, my LX200 doesn't track very well, so I stick to very short (5 second) exposures. Later, I discovered
that the scope was out of balance in RA, something I'll have to make sure doesn't happen again. Hopefully a proper balance job and perhaps some LX200 SmartDrive training will allow me to do
30-second unguided exposures in the near future.
The four pictures that follow certainly don't compare to Jack Newton's (or a lot of other peoples!). On the other hand, I'm already ahead of what I was able to do with old-fashioned film-based
prime focus astrophotography! And it took hardly any effort at all.
These pictures were acquired and added together using MaxIm DL/CCD software. Other than adding the pictures together and stretching them, no special processing was done.
| M15 |
30 seconds (6 x 5s) |
 |
| Looks like I need at least 1 minute for M15... |
| M2 |
1 minute (12 x 5s) |
 |
| Looks like I need 2 minutes for M2... |
| M27 |
5 minutes (60 x 5s) |
 |
| Looks like I need 10 minutes or more for M27... |
| M57 |
3 minutes (36 x 5s) |

| OK, I should have re-focused first for this one... |
