I've read a lot on tracking devices and also came up on the astrotrac, for it's reasonably low price.
The reason i didn't go for it was because of the diferrent reviews( negative).
Now after seeing your images they look quite amazing with some good tracking.
Could you give me your impressions on the device? Tracking, aligning, build quality (stability),power requirements,... It would be a lot of help.
The Astrotrac is an awesome bit of kit, especially if you already own a camera with a couple decent lens.
I'll tell you the bad first, the polar scope. It lets the AT down with its cheap plastic build quality. But this is forgivable when compared to the
The tracking is great, as long as you collimate the polar scope properly. I was getting 4 minute exposures at 300mm, and i kow somebody on flickr who
uses a 500mm lens with great results.
Alighnment is easy and only gets easier, you are up and running in 5 minutes. Thats whats great about the AT, its portable and you can set everything
up and be shooting in 10 minutes. Awesome if you live somewhere cloudy and see a gap in the clouds.
Buily quality is great as is th stability, but thats down to the tripod i am using.
There are a few power options, 8 batteries, from the mains, power cells. I am currently looking at getting some high quality rechargable batteries and
a smart charger.
Now, up until about an hour ago my Astrotrac was perfect. I tried to turn it on this morning to rewind it and there is no power. I have contacted
Astrotrac and am waiting to hear back from them.
Dont let this put you off though if you are consideing one. I am part of an Astrotrac group and this doesnt appear to have happened to anybody elses
