  1. Hi all, this is my first go at narrowband imaging. Total integration time of 3h 40min. Atik One 6.0 with Baader narrowband filters Skywatcher Evostar 80ed EQ6 Pro Guided with a Touptek guide cam and a 50mm guide scope Ha 17 x 300s Oiii 13 x 300s Sii 14 x 300s Flats and Bias calibrated. I did shoot darks, but it seems they somehow added noise to the stacked image, but I'm not 100% sure. Anyway I left them out on purpose. Stacked in DSS and processed in Photoshop, filters mapped to SHO. I'm planning on adding more data if the coulds ever clear. I'm still relatively new to all this so I welcome any advice. So what do you guys think? Cheers, J
  2. Thanks Vlaiv. I need some time to progress all this information, meanwhile I'll be practicing my processing with the subs I have available. Still learning this all. J
  3. Hi all, Apologies for the long and confusing title, I'm a bit confused with my narrowband data and need a little help. I have collected data of the Bubble Nebula in two different nights. From the second night I have 15 x 300s Ha, 15 x 300s Oiii and 15 x 300s Sii subs taken with Atik One 6.0 cooled down to -20C. The first night was a bit more cloudy and I was testing my setup and guiding for the first time properly, but I managed to gather about 10 x 240s Ha and 8 x 240s Oiii, camera cooled down to -10C. So, is it worth combining the data? Do I gain anything from it since the subs are shorter and the camera sensor is warmer? More data is more data, but are the subs that much more noisy, or does it make any significant difference really? And if so, how should I combine the data? I'm using DSS for stacking and Photoshop for processing Thanks in advance. Cheers, J
  4. A pity that it is cloudy. It has truly been a horrible couple of months here as well. I'll be sure to post the image after I'm done with processing. J
  5. Hi all, Are you out imaging today? If yes, which target? It's new moon and the skies are clear at last! I'm out imaging NGC 7635 the Bubble Nebula. Right now I'm collecting 300s Sii subs. This is my first narrowband project and first project with a mono CCD. it seems I will finally have Ha, Oiii and Sii an hour each, so I'll have something to practice my processing with. Ohand practically first time autoguiding too, so much to go wrong haha! Anyway I'm super excited and planning to collect more data in the future. It's been cloudy almost all winter. Cheers, J
  6. Thanks for the tips Olly! I might have a go with Artemis capture then. It will be a week or so until all of the gear has arrived. I can't wait to get some testing/capturing going on! Hopefully we'll have some clear skies. Cheers J
  7. Hi So I'm taking the leap and moving from imaging with a stock DSLR to a mono CCD and I'm asking for your help. I bought a second hand Atik one 6.0 with Baader narrowband filters and I will also be getting the LRGB filters as soon as possible, but may have to start with NB. I have also ordered a ZWO ASI 120mm mini as a guide camera for my 9x50 finder scope. Previously I have only managed 90s unguided subs (with round stars) so autoguiding will be new to me as well. I'm planning on using PHD2 for guiding and APT for imaging (or Artemis capture, if APT doesn't work with the camera). I do have a laptop. My current setup is: Skywatcher EQ6 mount Skywatcher Evostar 80ed DS-pro Canon 600D stock As I am just a beginner, I would be grateful for any advice and tips for getting started with CCD imaging, and with the software as well. I have been reading alot about CCD cameras and my head is spinning with all the new information. :) Here is a picture of M42 taken in February (stock Canon 77D). 16 x 90s lights + darks, flats, bias. Stacked in DSS, processed in Photoshop. Clear skies! J
  8. I've done 120s, but maybe realistically 90s subs without trailing. I'm at latitude 61 and because of the latitude bolts of eq6 I'm having trouble fine tuning my polar alignment. I need to loosen both bolts and adjust the latitude by hand. J
  9. Hi all After a long summer here in Finland it's finally getting dark again and I'm about to spend some money on new equipment (who would have thought, right?). At the moment I have the budget for either an autoguiding setup or a field flattener/reducer. I'm having a hard time deciding which one would benefit me more at the moment. My current setup is: Eq6 pro mount, Skywatcher evostar 80d and Canon 600d dslr (and a nikon d750, which I haven't used yet). DSOs are my main target. I do have a laptop and a power supply I can use. I was thinking about getting the ZWO ASI 120mm mini for my 9x50 finder scope or the Skywatcher 0.85x reducer/flattener. I know i'll be getting them both when I can, but it may be a couple of weeks/months. So what would you guys do? TIA Clear skies, J
  10. Thanks for the comments, it's very inspiring to get any results. I did a quick reprocess following a different tutorial. I did got some more detail, though it may be a bit noisy for my taste. The post-processing really is a challange. J
  11. I finally managed to actually get my setup out. This is my first time properly imaging with the scope and first go at M31. After spending most of the night trying to set everything up, I still got some subs! Canon EOS 77D, Skywatcher 80ed, EQ6-mount. 27 x 2min subs unguided 11 Dark frames 20 Flat frames 20 Bias frames. Stacked in DSS, processed in Photoshop. Still learning so feel free to give any advice. Clear skies, J
  12. Sorry for delayed answer. This was actually taken in Kihniö, Finland. Luckily we still have some nice dark spots here. J
  13. Hi, I just bought my first DSLR and happened to a reasonably dark site so I had a go with imaging the Milky Way! It was also my first time even seeing the Milky Way properly in years, what a feeling! Taken with Canon 77D and 18-55mm kit lens. Single 20s exposure, f4, ISO 6400. Processed in Photoshop following some online tutorials. Feel free to give advice! Cheers, J
  14. What a wonderful thread and great inspiration! This is my first DS image. I recently found my M45 subs from last year when I bought my first scope. Haven't had time for this hobby since, but I've read a lot about astrophotography. Also my first go with Photoshop processing. Skywatcher 150p Eq6 mount Canon 600d unmodded I think it was 32 x 30s subs, stacked in DSS and processed in Photoshop. No calibration frames as I didn't know of them at the time. Ps. I'm waiting for my new ED80 to arrive next week. J
