    M13

    Latest M13 from Saturday night (14/04/2019). It's a widefield taken with SWED80+ASI1600MC. 30x60s with corresponding 10x 60s calibration frames all FITS. Processed using PI and PS. Seeing was not great but can clearly see the propeller inside the star cluster, so I'm happy. The image has not been corrected for orientation. Appreciate comments if any.
  2. While learning some more about imaging with a ZWO 1600 MC camera and tracking with a QHY one on a Altair SWED80 on a CGEM-DX ...(long story cut short to spare the reader), M3 came up in a gap that I could not miss. I knew it was going to be small GC but defined at the star level if I did not overexpose. Nothing is perfect, and here is the the effort of my last night for a while (going to get a few bad bones sorted out). PI and PS have been good and patient . I like to 'lonely' aspect of the globular clusters but M3 has a great orange giant HD119081 as companion!
  3. This is my first M101 "widefield" taken with my SWED80, ASI1600MC. 60x60s at 300 & 200 gain combined in PI and touched a little in PS. This one was hard work due to excessive noise, which I managed to get under control (famous last words) using only 15s darks from a library. No bias or flats. It's taken me 2 weeks to complete with many a time when I was ready to trash all the data. It's an effort and only because I managed to make some progress that I post for comments and words of wisdom
  4. Hi, Thanks for the replies. I've got this crazy workaround which imvolves deselecting the reference image and running BPP again. It usually finishes this way. Ken: Can you be more specific about where you set the file type and bit depths? Again, thanks for the replies!
  5. Hi, This is my first post and maybe this has been asked earlier. Apologies if so, but I've not been able to find a post describing this problem although there are some that are related. So... I've used batch-preprocessing quite a bit but recently I'm encountering a problem with "Zero or insignificant signal detected (empty image?)" during integration and it always happens with the image that I choose as registration reference. If I avoid using an image as registration reference the process does complete without an error. Does this make sense? Kind regards, R:)
  6. I started using guiding as I learn more and more of this hobby :-) I can now get longer and longer subs (~120s) but have not managed to get pulse-guiding to work yet. Here are some integrations with about 10 x 120s darks and bias - no flats :-( processed in PI and PS. There are some artefacts emerging, which I need help with, such as halos, streaking background (drizzle problem?), etc. These where all shot using SWED80 + ASI1600MC (not pro). Please see below: Thanks for watching, R:)
  7. Hi Guys, Yes, this was my first attempt at guiding the CGEM-DX. I have not been able to get pulse guiding to work and I have to PHD2 calibrate a lot - but it pays! I'm making another post now to show and hopefully get some help with other issues that are appearing as I try to get longer and longer exposures. Many thanks for watching! R:)
  8. Quick 1st time setup with auto-guiding. Got everything working worth 60s+ until the clouds rolled in last night. Below there is an take on M42 and another of M51a/b. They are not perfect but the guiding worked and that was the whole point of the take. SWED80+ASI1600MC; Guide QHY5L-IIM+60mm+CGEM-DX - 50 x 60s Lights+20 x 60s Darks z 20 x 60s Bias. Comments are very welcome :-) R:)
  9. Thank you, thank you for your comments. I have to admit I've been working on Rosette with a D7200 and didn't quite manage to get an image I'd post here. But with the ASI this was a very pleasant experience. M42, on the other hand, is quite the opposite. "Easy" with the Nikon, but hard with the ASI. Perhaps the UHC filter is playing up with M42?
  10. Finally the skies cleared up for a decent while with no interfering moon last Monday. But it was cold and a bit windy! Powering everything up in the obsy I found my GPS (SkySync) was not working. Probably the internal battery ran flat again. I set the time and location manually on my CGEM-DX and off I went hunting for DSO's. I used my trusty Altair SWED80 with APO filter, ASI1600MC with an Opteron LP Filter and Sharpcap Pro. For each object below I took 20x lights+10x dark (for a master)+10x bias. I used PI for processing and a little PS. NGC 2244 M42 & Sh2-279 - Running Man I would appreciate any comments
  11. Awesome shots! - The top one stands out!
  12. This, and some moon images are the first taken from the new obsy using SWED80 and ASI1600MC. Still getting to grips with many details regarding this camera and exposure are too short for getting some of the grand detail you see here. This is the core of M42. I took 30x60s with a UHC filter in the FR. New camera, new obsy and lots to learn.
  13. Hi DP, Thanks for watching I use 500 frames because it is easier for me to work with smaller files, for example editing away frames that may contain clouds. I also don't process on the laptop in the obsy. I transfer the files to a desktop where I eventually stitch them together with PIPP and process with Autostakkert3 and PS. Kind regards, Rodrigo.
  14. Stack of 3 x 500 frames using ASI 1600MC on SWED80, processed using Autostakkert3 and the results stacked in PS. Thanks for watching. R.
  15. Merry Christmas to all and thanks for the the views and feedback. I've managed to get the SWED80 going it's true i do have to be careful walking around the tripod legs. Do far I've been lucky and will post a lunar stack on the imaging forums and an unguided M42 that marks first light for the obsy on the 24 December! The biggest challenge has been processing the data from an ASI 1600 MC. Getting the right debayer pattern has taken up a lot of time.
