  1. That´s a beautiful pano! I´m hoping to get back into astro photography myself and this is inspiring!
  2. I agree with what is said above. I would (and I did) start with a camera lens. The shorter the focal length, the less demand for accurate tracking. When you get the hang of that, you take the next step up in focal length and/or tracking. One of the best lenses for astro photography is the Samyang 135mm f/2.0. Yes, it is wide and you will not catch small galaxies but it is great for larger areas with nebuale. Longer camera lenses (not zooms) will probably cost you as much (or more) as a budget telescope and will have a less suitable focusing mechanism. If you don´t already have a telephoto lens, I wouldn´t buy one just for astro photography.
  3. Damn... for something to be that easy and still that hard 😂 Thanks, both of you!
  4. When looking here it seems like the backfocus varies with the FL. So 61 mm in my case? https://davidastro.com/en-eu/products/ts-optics-0-79x-photoline-reducer-corrector-2
  5. Wow, this is embarrassing... I can no longer remember how to connect my darn gear. I have the TS Photoline 80mm f/6 refractor, a TSFLAT2 corrector and a TSFLAT2A adapter. I also have a Canon EOS T-ring adapter plus a whole lot of distance rings and stuff. Not sure all of it is supposed to be used since I also have a ZWO 1600 MM-Cool (not going to use that at first). I also have a TS Optics 0.79x reducer/corrector. HOW do I attach my Canon 550D DSLR to the telescope with the corrector or with the reducer? For the life of me, I can´t remember or make it make sense when googling. Can anyone help me? It can´t be that difficult, right? Can I just attach the 0.79x reducer to the T-2 ring and go?
  6. This was all shot on the night of February the 27th this year. A fantastic night that I got to enjoy before I got ill (feeling better now). The night was pure magic! Aurora clearly visible to the naked eye, displaying some pulsating and flickering that I´ve never seen before. Perfect conditions - no wind, everyting calm, the only company I had was an owl and a fox making sounds in the forest behind me. Here is a film I made from this night - I hope you will enjoy it! https://youtu.be/k3PaA5wFHxg
  7. The Astrotrac is hard to beat for pure portability and still gives great results with gear that is on the heavier side. You just need a tripod that won´t flex. I use a carbon fibre Sirui R-3213X and it works great for me.
  8. That is awesome, you got it working again! I have powered mine from the outlet in my car so it must have been something wrong with the capacitor to make it fail? Also, I must say that I´m dissapointed to hear that Astrotrac no longer service or offer any help with these since they were a high end product (compared to other portable trackers) and cost quite a bit.
  9. I haven´t had the time or energy to get my mount running this season so I thought I would give my Astrotrac a bit of a challenge Heavy Sigma 500/4.5 lens and Canon R6, without counter weights or anything. Worked out quite well. I´m happy with the results considering it´s only 32 minutes of exposure @f/5.6 https://youtu.be/AlgMyoBbCZE
  10. Had a short break in the cloud cover, enough for me to at least get a few seconds of video and some images :) https://youtu.be/b8tOIvMw3-0
