10 Good
  1. Thanks, fizzydx. I just tried the number again and got the answering machine as well. In the meantime, Ian from Altair answered the email I sent again this morning and told me that Altair shipped the part I ordered as soon as I ordered it, before contacting me. He said that the item was small enough that they shipped first and would determine shipping later, to be sent along by invoice. Good, fast service if that's the case! Not sure why I did not hear from him sooner, but it certainly seems all is well. Thanks for the help. This is my first experience with Altair or any UK vendor. Val
  2. Oh, now I just heard from them. Glad to hear my situation seemed anomalous.
  3. Hi, folks, I tried to contact Altair Astro through its help email, then ordered something because it looked like they were willing to ship overseas, then tried to call. No email answer back, nothing but a receipt-bot answer to the order, and I can't get through by phone. Any suggestions? Val
  4. Hi, Mike, Nice to see someone else shooting with the 10" Newt. Very nice, image. The superior resolution is the draw. Good on you, Val
  5. The best way to judge between the two is to look at images taken. I have used both a 10" f/4.7 newt and a 80mm ED f/7.5 refractor to image. They both have their advantages, but not at 1200mm. I can't imagine even trying to image at f/15. The stars in the refractor are round, so if you take the rig down one night and want to go back to the same object the next night, you can, easily. In the newt, the stars have spikes. If you go back the next night and the camera isn't exactly in the same place, the stars have blurred spikes or two sets. I have to set up and take down each night. When imaging with the newt, I try to get the image all in one night. I love the view at 1200mm. I bought the newt specifically to image at that focal length. It's the beginning of the focal length needed for galactic detail. But if you are going to image galaxies, you will want a faster scope. Imaging at f/4.7 is much easier than imaging at a slower speed. Having said that, I agree with the post above about the mount. You will need a hefty mount to control the 10". Moreover, on my scope (an Orion), I found too much flexure between guidescope and main camera. I now use an off-axis guider. I know of people who guide a 10" newt with a guidescope, but my scope would not do it beyond about 120-second exposures. Polaris B Polaris B Blog
