  1. It is called "walking noise" there are several possible reasons for it such as differential flexure, focuser flexure or polar alignment which causes a slow creep in the guiding. This is a fairly common issue....now the fun part....figuring out what is causing it. Dithering your guiding typically helps with it too. John CCD-Freak WD5IKX
  2. I found out the hard way that your red computer screens may be fine for your eyes but they can reek havoc with your images. While imaging under Bortle 1 sky with a new scope I inadvertently allowed some of that red light into my scope resulting in serious red gradients in some of my images. Be sure your screens are shielded from you scope. It pains me to think of the images I compromised after drive 850 miles to image under Bortle 1 sky. Fortunately not all of my images were affected and Astro Art 7 gradient removal routines do a nice job repairing them. John CCD-Freak WD5IKX
  3. I got this idea from a buddy on Cloudy Nights. Happy Halloween !!! John CCD-Freak WD5IKX
  4. It is possible to get good OSC images under Bortle 8 sky but it requires much more total integration time than my image and filters can help too. I have seen very impressive OSC images taken under heavy light pollution....I fortunately can get to Bortle 2 sky in about 3 hours. It still doesn't change the fact the ASI-533MCP is a great camera. If I lived undet Bortle 8+ sky I would probably go mono and shoot narrow band. John Love CCD-Freak WD5IKX
  5. The ASI-533MCP is a great camera with very good specs which should be able produce good images with the right techniques under Bortle 8 sky or Bortle 1 where my image was shot. Most of my imaging is done portable under Bortle 2 to 4 sky. I just wanted to show what it is capable of. John Love CCD-Freak WD5IKX
  6. I went with the ASI-533MCP and have not regretted it. Low noise, No amp glow, deep well depth etc...what's not to like. I even like the square sensor because it frames most objects without a lot wasted real estate. The attached M42 image is only 60 x 1 minute. John Love CCD-Freak WD5IKX
  7. I am getting the SS15028HNT dialed in and I am having fun with it. I want to try a larger sensor next time I get some clear sky. 120 x 1 minutes Processed as Lum. ASI-533MCP John Love CCD-Freak WD5IKX
  8. I went with the ASI-533MCP and have not regretted it. I like the square sensor, the no amp glow, 14 bit ADC and good well depth. It produces clean data which is usually easy to process. This is one of my favorite images I have made with it so far. The Horse Head and Flame Nebula complex 60 x 60 seconds (1 hour total) taken with a Sharpstar 150mm F2.8 Hyperbolic Imaging Newt. John Love CCD-Freak WD5IKX
  9. I am starting to process the 20+ GB pile of image data so here is another image from the Rodeo,NM trip. IC1396 Elephant Trunk Nebula. 150 x 120 seconds (5 hours total) captured over several nights This is a tough object and I am still working on this on this one to see what I can pull out. I want to try to capture some Ha data to add to it. Edit: A buddy of mine pointed out what looks like a horse to the right of the Elephant Trunk. (^8 John Love CCD-Freak WD5IKX
  10. I have the solid tube 10" RC and here is how it is configured. With a heavy cam like the QSI I push the tube forward to get balance. John Love CCD-Freak WD5IKX
  11. I just got back from New Mexico today. I captured over 20 Gigs of image data over six nights so now I start the careful image processing. Here is another quick stack of NGC2264 I don't have my notes handy but I think this was 75 x 120 seconds. Much more to follow. John Love CCD-Freak WD5IKX
  12. We stayed for a week and had 6 good nights. I captured over 20 gigs of mage data so I will be busy for a while processing all that. I will post more images as I work through the pile. We plan to go again around May for another week. Having a caravan makes it very comfortable. I call mine the "Moonlight Manor" John Love CCD-Freak WD5IKX
  13. I had to drive 850 miles to get to it but it has been worth the trip. I can only get out here a couple times a year. I torture myself the rest of the year as I suffer with light pollution and crappy weather so I feel your pain. Getting to sky like this is always a treat. I have become a "Dark sky junkie". John CCD-Freak WD5IKX
  14. Out in the "boot heel" of New Mexico doing some imaging this week. Here is the Sharpstar 150mm F2.8 Hyper Newt riding on an AP900GTO mount under the Bortle-1 DARK sky doing it's thing. "Life is good" !!! John Love CCD-Freak WD5IKX
  15. Here is another SS15028HNT / ASI-533MCP image from New Mexico. I just did a quick process of the B33 Group (B33, IC434, NGC2024, NGC2023, IC431, IC432 and IC435) 60 x 60seconds (1 hour total) I am looking forward to adding more subs and doing a more careful process. John Love CCD-Freak WD5IKX
  16. Another image from New Mexico. IC5070 Pelican Nebula. 80 x 60 seconds (80 minutes total) I plan to add some more subs tonight before I reprocess with all the calibration files. Gotta love Bortle 1 sky !!! John Love CCD-Freak WD5IKX
  17. Here is another quick stack of some image data I took last night. IC5070 Pelican Nebula 80 x 60 seconds (80 minutes total) I plan to shoot more subs tonight and I will reprocess later with all the calibration files. The combo of the ASI-533MCP and the SS 150 F2.8 Hyper Newt is proving to be much fun. John Love CCD-Freak WD5IKX
  18. It will do that but you have to use the 2015 Atlas data set selected in the upper right corner to get SQM readings. John Love CCD-Freak WD5IKX
  19. Arrived in the "Boot Heel" of New Mexico yesterday and had a great first night under clear Bortle 1 sky. Six more to go. Here is a quick stack of some M42 data I captured last night. 180 x 15 seconds for a total of 45 minutes with an ASI-533MCP and a 6" F2.8 Hyper Newt. John Love CCD-Freak WD5IKX
  20. Here is a quick stack of some M42 data from last night under Bortle 1 sky. I will be tweaking the collimation a bit today as I search for the sweet spot. This OTA is a "photon sponge" ... 180 x 15 seconds for a total of 45 minutes with an ASI-533MCP and Astro Art 7. Still need to take Flats and Darks for calibration. Six more nights to go! John Love CCD-Freak WD5IKX
  21. We will be arriving in New Mexico tomorrow....."Gentlemen....Start your imagers" John Love CCD-Freak WD5IKX
  22. Was it this one? https://www.lightpollutionmap.info/#zoom=3.04&lat=54.3547&lon=2.7220&layers=0BFFTFFFFFFFFFFFFF It has multiple data sets and the ability to get SQM readings for any spot you click on. John Love CCD-Freak WD5IKX
  23. There is no substitute for DARK sky.....I have become a "Dark Sky Junkie". You have not lived until you spend some time under Bortle 1 or 2 sky. Next week some buddies and I are heading out to the "boot heel" of New Mexico for a week of imaging under Bortle 1 (SQM 22.00) sky and low humidity. We planned this trip since the Okie-Tex star party (Bortle 1) was cancelled this year due to the Covid 19 outbreak. John Love CCD-Freak WD5IKX
  24. I sure hope they come out with mono versions of the IMX533 based cameras. I would like to pair one with my ASI-533MCP. John Love CCD-Freak WD5IKX
