  1. Welcome, enjoy the retirement and the chance to finally use your scope.
  2. Awesome job dude! Crazy to think it went bang 52 million years ago and we are only seeing it now!
  3. I look forward to seeing it. I am upgrading soon, so will be interesting to see the difference.
  4. Decided to have a try at M61 and the supernova. Didn't think I would get much with my 130SLT, but quite happy with how it turned out. 29 x 90 seconds @ Iso 3200 10 x dark, flat and bias Stacked in DSS with final edits in Affinity Photo

    My favourite pictures and the odd video.
  6. Managed to get 15 minutes of data on M13 last night in between Sunset and Moon rise. Was testing out tracking as I had changed backlash settings. Was quite pleased as the stars were nice and sharp. 10 x 90 sec @ Iso 3200 ; 10 x dark, bias and flat, stacked in DSS with final edits in Affinity Photo.
  7. I have re-installed DSS and took some images of M13 last night (10x90sec) I also spent some time looking at the backlash settings as they were fairly high, I have reduced them and it seems smoother. Not even sure if it makes a difference in actual tracking? I now know it isn't the tracking as M13 was fine. Image was stacked in DSS and turned out well. Will wait for a really clear night and try again on a comet.
  8. Just tried a new stack with kappa-sigma clipping and this I took each light frame and increased the clarity (made stars and comet brighter) of each light frame. The final stack was better but had a double image. i.e. every star had another below it. Looking at it I may have even forgot tot stack the comet! Think I need to wait and get some good data and try again.
  9. The top image didn't have flats, but even when added, it still comes out the same. I am thinking it is the software struggling to keep the comet and star positions right when stacking. When you go through the light frames, the stars jump around a lot. Although the pictures are clear, the stars move a bit each time (not in the same direction either so not tracking, it would be like taking a pictures hand held), so could be tiny movement from a loose gear or some other tiny movement in the setup. When stacking this then makes it hard for the software to keep up with position of everything in the light frames and this makes it put one or two frames in a different location thus creating the lines....if you get what I mean, not sure I even do LOL
  10. I have used those settings and it didn't work (don't really understand it all yet, so just checking boxes half the time!). As for dithering, I don't think the box was checked, but that is something I have yet to understand/test. The learning continues...….. LOL I had the same with some working and some not, will try other methods to see what I can do, but like vlaiv pointed out, I think some better data in my light frames will help DSS in it's job. I had a great picture a while back, but could only stack on the comet, luckily the picture still looked good like that. I will use the next few weeks to try out some manual stacking etc. At least I will have something to do for the cloudy nights
  11. When I look at each frame there is movement in the stars and the comet is slow so that could be a problem for the software as you say above. To be honest I had always just used the standard settings and not sure what I could/should tweak as it would just be guessing. Will have to look into it more, so much to learn and get my head around LOL. I was hoping someone would say "just click this button and hey presto" ha ha, if only! I have also just seen another thread on here about doing the two stacks (one on comet and one on stars) separately in DSS then blending myself in my photo editing software (Affinity Photo), again, so much to learn! ….but I know it will all be worth it in the end
  12. Forgot, top image with trailing I didn't use flats or bias frames (only darks), but even when I use flats and bias I still get trailing.
  13. Hey all, I have been using Deep Sky Stacker to stack my comet images. I have used the stack stars and comet before without problem, but for some reason this past few months, every time I stack now I get a slight star trailing as in the image below. I decided to have a quick go at Y1 Atlas last night (knowing the Moon and weather were not on my side) just to have some data to play with and test, but ended up with the same star trailing. I don't know what could be causing this as all my light frames (60sec @ iso1600) are clean, when I stack it as a normal star stack the stars are pin sharp (comet blurs obviously, but this tells me that the tracking is fine), I have made sure the comet selection is good checking each one thoroughly, I have even reset to default settings. I used to just click, save and stack and it worked fine. Not sure what is going on now? 20200505 C2019 Y1 Atlas.TIF
  14. I have a few pic's on here in various posts, but most are on @photoncass if you have Instagram. I use a 2" barlow that is x2, but it is what you call non-telecentric. This means the closer I have it to the sensor on the camera, the less it multiply's the focal length. I also use a set of adaptors. This allows me to get enough 'in' focus. This sounds complicated, but to start with a standard barlow lens for your eyepiece size (not sure what it would be on yours? 2" or 1.25") should work fine (maybe see if you could borrow one before spending out any money?). The top of the forum has a link to the FLO webpage shop. You can find various ones on there. Do bear in mind that using a barlow will slow your telescope down and mean that you need to do longer exposures or higher iso. To get real 'prime' astrophotography, it is best to get a scope designed with astrophotography in mind. I was looking at moving my mirror closer, but I would probably break something LOL I am looking at a PDS or Comet Hunter next. Below is my barlow setup. I have a Canon t-ring adaptor, an svbony converter (eBay), an additional svbony extender (eBay) and the barlow lens itself taken off a revelationsastro kit. By attaching the barlow to the one converter I get about x1.5 magnification which allows me to fit the moon in shot. If I am imaging galaxies etc I use the second extender and get true x2 magnification. I also recently cleaned my mirrors and then took a picture of Capella with a bahtinov mask showing good focus (see bottom image)
