Man! love all the shots posted here. Wanted to learn AP myself. I got an old NatGeo Reflector Telescope but unfortunately there's no available mount that can be used for my DSLR to it. Keep posting guys!

Hi Vicuna,

For objects like the Moon you can use a compact digital camera held to the eyepiece. This can produce very good results. Auto mode (with auto exposure and auto focus) is the best setting to start with. You also need to vary the zoom on the camera to get rid of vignetting at the edges.

Some compacts work better than others. Those with fairly large lenses seem to be the best. The ones with tiny lenses like those on mobile phones are the worse.

Hope that helps.

Mike.

Yep. I tried that one way back Mike, using a mobile phone though. At that time I had no camera whatsoever. hehehe! IQ is not the best but I've had a few good results. Thanks Mike!

Hi Vicuna,

Mobile phones don't work well at all for this purpose the lens is far too small. A lens with a diameter of 15mm-20mm is the best I have found for this. Much larger, like a DSLR lens doesn't work that well either.

There are a lot of very cheap 3MP cameras available in the UK for just a few pounds; plenty on ebay. The best one I've found is an old Olympus C300 zoom; may still be a few of those around. That has a 15mm diameter lens and works every time. The Fuji 2600Z is another good one, and Fuji and Olympus cameras in those ranges with the same size lenses.

Good luck with your Astro-photography,

Mike.

I'll go grab a camera then. I know we have that somewhere. LOL! Anyway, thank you very much for the tips Mike!

Just a quick shot from my car when I was heading across Death Valley at midnight. I had my dog in the car and it was hot, so I didn't stay long. In a couple of weeks, when the moon is new, I'll try again. This is my very first attempt at a milky way photo. Still much to learn.

Hi everyone,

I'm a new PC member and I'm glad I found this thread. My main interest is Wildlife/Nature, but I love dabbling in AP. Looking forward to learning and contributing.

Jack...love the DIY Astrotrac on the first page !!

Here's my first contribution; Classic star trails... a 42 minute exposure centered around Polaris. The reason for the false color is to help the star trails pop out. Taken in our garden in Switzerland.

Wow, Ted, great photo! Was this a solid 42min photo, or did you stack shorter timed ones together?

Single 42 min exposure. I was a little lucky... it was a perfectly still night, as you can see by the relative sharpness of the trees, which show almost no evidence of motion.
