  1. I know I am very late in posting this but thought I would anyway. I see on here many time lapse images of a streak across the sky. This day I was ready with my Canon T31 on a tripod with fluid head. I set the camera to sports shot and multi shot. I was using the Canon 75-300mm lens at 300mm. I started tracking manually when the station came into view and shot until it faded out. Out of some several 100 images I got one good one! This is highly cropped to get any detail at all and the station is only 10's of pixels wide but it is the ISS and discernible! Due to the sun and my angle of the shot not all of the solar panels are lighted but I was pleased with this attempt. Eric
  2. Hi all! After a very long hiatus from anything astronomy I took a vacation and went to the Nebraska Star Party. My main goals there were to do some visual observing with my 20" Obsession Classic telescope from a pristine dark site. The goals were achieved in spades! I took one night there to set up the AT72ED and do some imaging. Well things went wrong all over the place and needless to say due to blue screens and a portable storage device failure I thought I was left with nothing. I did find 1 image that somehow was saved. It was a single raw frame of 180 seconds at ISO 800 with an unmodified Canon T3i. I shot this with the AT72ED on a guided Sky Watcher EQ-6. Image was processed with Digital Photo Professional, Photo Shop Elements 2018, and Astronomy Tools for Elements. After many iterations, I am satisfied that I have pulled as much information out of one frame of data as I am capable of with the tools I have. I tried very hard not to over cook or use to much noise reduction. I was lucky to be at such of a dark site that just one frame held so much information. Eric
  3. 1 Frame Wonder M8, M20, & M21

    Very nice Shane. Makes me realize that I did get heavy handed with the noise reduction and saturation! Wish I could have salvaged more of the images. Micro SD card took a dump or I would have had 30 dithered of these images. Eric

    BTW here are the kits. Eric

    Here is the light pollution chart for the NSP. Eric
  6. 1 Frame Wonder M8, M20, & M21

    Thanks guys. I know it is hard to believe that is just one frame so I made a link to to the original CR2 file it came from. I would like to see if you all can get even more from the data than I did with my limited tools. Looking forward to seeing your results. Drop Box CR2 Eric
  7. From the album Astro Images by Eric

    1 frame of 180 seconds @ ISO 800 with a Canon T3i and AT72ED.
  8. I noticed an uncanny resemblance and thought to myself...Have we created the beginning of our end as these things get smarter and smarter? Could it be Lexons? Eric
  9. Australia's New Space Agency?

    I heard they were going to launch a Probe called "Heliospheric Observational Limits Experiment", or HOLE. Eric
  10. So It Begins!

    Whoa Ray! Sarah Connor indeed! Skynet Eric
  11. Today's EPOD

    Love them Red stars myself! Eric
  12. Happy Birthday Eric

    Thank you. As far as astro presents, none so far. I would gladly be satisfied with a good night of seeing! Have to work all week long and my astronomy adventures are limited to Saturday nights...weather permitting. Thanks again and clear skies to you all. Eric One year closer to the big dirt nap!
  13. Mega-Deep M45 image

    Simply Spectacular! Eric
  14. Fractal Broccoli

    Broccoli makes me Fractal a lot after ingestion! Wonderful image! Eric
  15. This is a post I should have made a long time ago but just now getting around to it. Back in Dec. of 2015 I picked up a new telescope (New AT72ED). I had mounted it on a ADM side by side dove tail. As you can see in the link this set up was very tail heavy when all the gear was mounted and focused. Although the scopes are fairly lite in weight and my SWEQ-6 would surely handle the balance problem, I had 2 other mounts that would not, a Celestron CG5-ASGT and an old Vixen GP modified for AP. A counter weight was in order to get this setup to balance. I had some parts laying around. A couple of 3lb counter weights and shaft from an old telescope. A block of aluminum and some time to do it. I was lacking real estate as I wanted to keep my RACI finder scope mounted in the center between the imaging scope (AT72ED) and the guide scope (Celestron 70). Here are the parts for the project.

  16. A balance problem solved

    Completed project used all Stainless steel hardware and counter weight and block painted. Now everything balances great! Eric
  17. A balance problem solved

    I now worked on the ADM dovetail. I through drill it for 1/4-20 SS socket head screws and tapped the bottom of the block. The finished assembly. Eric
  18. A balance problem solved

    I then drilled and tapped the block for the SS 10-32 screws to hold the finder bracket. I through drill the holes for 10-32 then drilled the bottom for 1/4 20 bolts that would come in through the bottom of the dovetail. Eric
  19. A balance problem solved

    I wanted to make a counter weight bracket that would mount the counter weight shaft and the bracket for the finder scope and keep then center mounted. This raised the bracket for the finder a bit but that was a good thing. I started with machining the block to accept the counter weight shaft. I through drilled the block for 1/4-20 bolt and counter bored the pocket for the shaft. Eric
  20. The Coma galaxy cluster

    That HyperStar is a fantastic instrument. Eric
  21. Rosette nebula Zoom-In Zoom-Out

    I like the Sky 90 image for this object....frames better. Eric
  22. Markarian Chain - Zoom In/Zoom Out

    Very much like the HyperStar image! Eric
  23. 08-21-2017 Total Solar Eclipse Time Lapse Eric
  24. I packed up the camper and traveled about 300 miles from home to a remote spot in Nebraska. A farmer there had opened up some of his land for observers to view the eclipse. We were about a mile and a half off the center line of the shadows track. We got a 2 minute 35 second Eclipse! I just cannot describe the experience with words. I caught some images of the most special moments. First is when it first reached totality, then seconds later as the limb of the Moon broke and shot through crater rims, and then the "Diamond Ring"! Hope you enjoy! Eric
