Here are a few of my comet images that I had taken in 2013.
Very nice! What did you use to capture these?
I was using a Canon T3i camera mounted piggy-back onto my NexStar 8SE telescope for tracking the comets. Then on the camera I had a 50mm lens, ISO 1600, f/1.4 and 4 sec. exposures. I can't remember for sure how many images was in these right off the top of my head, but there were at least a couple of hundred total in each comet picture. Then they were stacked using the registax program to bring out the tails.
Can you please explain since your scope is guided, why take a bunch of short exposures instead of one longer one?
Made a mistake...I'm really sorry I posted the wrong information with these images. The first image was a 30 sec. exposure and this is how I caught the meteor. The other images were stacked but not mounted on the telescope. Sorry for the miss information.
OK. Thanks. I recently got an FZ200 which will do up to 60 sec, and I have an ETX-90 so I need to fab some sort of piggy-back mount. And wait for clear skies in Western Washington. Hah...
So you can either do guided, or a bunch of short exposures from a tripod with no foreground and stack them, correct?
I still have my ETX-90 that I started with, that I made an adapter that fits into where you place the eyepiece. Turned a piece on a lathe to fit the opening and then placed a 1/4-20 stud on it to mount the camera. Works really nice. Still use it sometimes, instead of setting up the big telescope.
Guided with the telescope and the fixed with the tripod. Guided I've went as long as 240 sec exposures and the shots turned out great. Tripod 30-45 sec. exposures depending on the lens I used. Either can still be stacked to bring out detail in the images though.
