  1. Hey Vacuum. I know you have a DSLR but if you ever move on to CCD you should check out http://www.newastro.com . His books are pretty much the "bible of ccd astrophotography".

  4. Nice star trails! I'm not sure what technique you used but I recommend taking multiple exposures (such as 40 x 45 second exposures) and then stacking them. This should cut out the light pollution drastically. Keep up the good work! Can't wait to see more.
  5. At first I was stuck with the image attached below. I thought it was an issue with field rotation because PixInsight said there was -.28 degrees field rotation between each image. You'd be surprised that all that smudge in the upper left was because I was stacking a image that was smeared most likely by the telescope possibly being nudged. I noticed there was a time difference in the files so that's what made me think the image was bad. After removing the bad image from the stack it came out nicer.
  6. I finally found out what was wrong.
  7. Lol nice picture :P

  8. I don't know how to edit or delete my previous post so: Sorry those links didn't work, I sent them to you through PM. By the way I am using a stellarvue large format CCD field flattener.

  10. Sorry it's so noise, here's a better clip of it. The upload must have degraded it. I'm on a Mac by the way so DSS wouldn't help me sadly. I do have Photoshop CS6 but I am not sure if it would help or not. Christopher
  11. Fort Davis has nice viewing areas. I used to live in Corpus Christi and Kerrville, Texas.
  12. Ooooh I am very curious to see how your images turn out! I have the same camera
  13. You're birthday is a day before mine!

  14. Hey Adam, I might suggest a VERY good tutorial website that you should visit. The tutorials do cost money but there are some free ones you can check out. They've helped me a lot. Nice work on Andromeda! Here's the website: www.IP4AP.com
  15. Ok so I took this data about a month ago. I processed the data through PixInsight (I'm rather new to the software so maybe I missed a step). I think initially this field rotation was due to a polar alignment issue, although I don't know for a fact. In the picture you can see that after processing the bottom right is almost crystal clear but on the top left the image is fuzzy due to the field rotation. Is there something that can fix this? Even if I have to go into each individual file ( there are about 50 of them ) to correct something, I think that it would be worth it. Thanks! Christopher
  16. The total exposure was 45 seconds and it was a single stack (so no stacking). Darks are automatically subtracted after the picture is taken via inside the CCD. I don't know how to take flats or bias or what they are, so I haven't done those yet.
