  1. That would be great, will keep that in mind for future versions 😁 I was very satisfied when I came up with the idea to be able to destroy clouds, dream come true 😀
  2. Hi everyone, During the summer I've decided to make an astrophotography game for iOS. Don't know if such a game ever been made so I thought it was about time to make one 😀 The game is called Space Exposures and you can download it on the App Store - https://apps.apple.com/se/app/space-exposures/id6451156789 You can read more about the game and how I came up with the idea on my website - https://astrofotografen.se/en/space-exposures/ It's free to download and don't contain any ads, hope you like it. Clear skies!
  3. Thanks guys for your comments. I'm still learning how to process data from the UHC filter, narrowband imaging is new to me.
  4. Thanks. Yes, I use the Sky-Watcher flattener.
  5. Finally I got first light with my new telescope, a Sky-Watcher Esprit 100. First target was NGC 9662 and in total I got 3 hours and 30 minutes of data from one night. In total I got 42 subs with 300 seconds taken with my Nikon D810A and a Astronomik UHC clip-in filter, all mounted on my Sky-Watcher AZ-EQ5 GT. Guiding and exposures was all controlled with my ASIAir Pro. Stacking and calibration was done in PixInsight and final touches in Photoshop.
  6. I’ve been doing deep sky astrophotography on and off for twenty some years, mostly off recently, but now I’m really keen on getting back into this type of photography. I just ordered a SW Esprit 100 with a SW flattener to use with my Nikon D810A camera. Recent years I’ve just visited dark sites with my Nikon and tele lenses, but now I’m would like to start doing some narrowband photography from my back yard (Bortle 6). My plan is to buy a cooled dedicated astro camera later on, but for now I will start using my D810A. So, as for filters, I’ve been looking at the different Optolong filters and they look very interesting. I don’t want to invest to much money in a filter since my plan is to go mono (maybe next season) and will then buy narrowband filters for that camera. 1) As for clip-on options for Nikon full frame, it doesn’t seem to be an L-extreme or L-enhance, just the L-Pro, right and L-Pro doesn’t seem to be the right choice for NB photography in light polluted area. Since I have access to fast telephoto lenses (600mm f/4 and 300mm f/2.8) it would be nice to be able to use the filter together with these lenses. 2) As for 2” filters, would you recommend L-extreme or L-enhance for my setup and location? Thanks and clear skies! Göran
