That "barn door" is a piece of brilliance I don't have the high iso the K200D is only 1600.the mid lenses I do have and the dark skies.At least I have some idea now.a lot more to it than just pointing a lens at the night sky.

Or you can get an equatorial telescope mount with motors and a nice apochromatic scope on top of it, with a much higher budget and it's a never-ending line from then on.
If you're good with tools or know someone who is, a well-made barn-door tracker can be great for tracking (there's several designs, some are more advanced and allow higher exposures).

I have the dark skies.benefit of living in the wide open country spaces in Australia or at least less than hours drive from town,I can spot the satellites,shooting stars/burning space junk or what ever they are Clear open skies on a good night.įuji XE-1,Pentax K-01,Panasonic G1,Panasonic G5,Pentax MXĪuto Rikenon's 55/1.4, 1.8, 2.8.

So we pointed the thing towards Saggitarius, the Lagoon nebula ( M8 ) and the Triffid ( M20 ). Not solely my attempt though, I had two friends with me, one brought his EQ5 motorized mount and the other had a borrowed CZJ 180/2.8.

But I'm thinking that, despite its considerably smaller size, resolution may hold well enough where even my 650mm f/6.8 might be adequate for some astrophotography subjects. My old Meade 10" had a focal length of about 2000mm, and I found that I could adequately fill a 35mm frame with M31 at that magnification. I think I used a teleconverter in the second shot below. I have to use Live View to make sure the focus is accurate. I've found that I can get pretty good shots of the moon with a decent 500mm lens mounted to my Canon crop body. Don't have any telescopes anymore though, so I would have to make do with photographic lenses. I'd like to try this stacking technique one of these days. What can be done with digital outfits now is really quite remarkable compared to the way it used to be done. That was like ancient times compared to now, though. I lived in the Los Angeles area, and it was about a 160 mile round trip for me to get to a place with truly dark skies, so I didn't make it up there as much as I liked.
