hello all! I currently live in a polluted capital city and thought photographing the stars was never going to happen for me until I saw the astrotrac. I now...

Hi Rainer, I went back to using the 200mm again last week and had a great time. Its amazing how easy it was to get some good results. Happy New Year. Gain ... ...
What was the difference in weight? The 200mm certainly weighs a lot less than my 3kg Nikkor AIS 300mm f/2.8 ED. I just bought a used Canon 5D which is full...
Rainer, Gain, und alles, For the past 6 months my astroimaging has been with only prime lenses, 20, 50, 80, 100, 135, and 200mm all on my 350DM on an AT320....
Hello Perry, I've managed 2-2.5min subs at 1200mm fl. Though not all were good, I did manage to get 10 good ones on the session I tried it. With my 200mm, it...
Hi all, Just started using my new TT320X with a Canon 350D mounted on top. I thought I'd use a technique for focusing that Nik Szymanek mentions, i.e....
Im reading hear & there about the new pier & wedge that will be showcased in a month, but am unsure what a pier & wedge would be. can anyone explain? from...
Hi Tim With the KitLens i use manual focussing with LiveView of my 450D. Works fine. With the 70-200 TeleZomm @ 200mm i use the autofocus on a bright star with...
Hi Rainer, Thanks for the comments. I'm expecting a 40D any day now, which also has the Live View facility. Am I right in thinking that you can "zoom" the...
Hi, A pier simply refers to a permanent or semi-permanent mounting, such as a concrete pillar or concrete-filled length of pipe, typically concreted into the...
Hi Tim, I use the Live View on my 450D, which possibly could be quite similar to your 350D (or future 40D). This also allows me to zoom in 10x, getting the...
Hi folks, Not that I want to `steal' anyone's favourite observing locations, but I wondered if there are any suggestions for dark, safe spots around northeast...
Hi Andy, Thanks for the info. The 350D doesn't have Live View, so focusing on that has to be via another method. One reason for moving to the 40D is the Live...
Hey Tim, I originally had a Nikon D60, which I traded in for my 450D as it didn't have Live View, and it makes a MASSIVE difference. It may sound lame,...
Hey Tim, You'll notice that in the same digest as your post I had one mentioning my being tutored in focusing and framing via my prime lenses + the 350DM. ...
Hi Tim, Use the center focus spot and focus on a bright star, i.e mag 2 or greater. If you hold down the shutter while keeping the star inside the focus box...
When I daylight auto focus on a very distant object;;switch to manual and tape my lens,,my 50mm 1.8 is spot on.I take a 45 sec. sub and check it out on my...

Hi Andy Similar but much better. On CN is a big thread about this. I made my layout for the megrez72 with a Bathimov generator. Then imported the result in...
Then too, isn't focusing more forgiving with a 50mm FL lens than with a 200mm or higher? Length of exposure before noticeable trailing w/o tracking/guiding...
Hi Rainer, Thanks very much for this - I'm surprised I haven't come across them sooner. Now I've done some digging around they look popular and very effective....
Hello group! Does anybody has any experience for mounting a Televue 60is plus a Canon 450D and using the TT320X for tracking? The scope seems reasonably...
Hi Rainer - looks good, nice range of colours. If you don't mind, how did you combine the different exposures? I've read Jerry Lodriguss' layer mask method...
Hey Edgardo, Balance and stability can be a problem. It depends on what your tripod is, what your alt-az head is, and the ball head and the optics on it. ...
Im looking to buy the astrotrac very soon. The end of February barring any unforseen bills (hope that doesnt jinx me)! I was just interested what sort of...
Hi Andy Thanks for your answer. Yes, I used the layer mask method. I have only PS8 from the CS1 suite. Thats the reason i have no experience with HDR-feature. ...
