Re: Window Astrophotography 2019
I've managed to add a couple more hours of OIII and SII data on the Running Chicken, totalling 9.3 hours so far. I've also handled the stars a little more carefully in the processing this round: https://c2.staticflickr.com/8/7850/46453291294_78f10874af_c.jpg Full FOV https://c2.staticflickr.com/8/78...

Window Astrophotography 2019
2019 has been a rather productive year for imaging, with several streaks of clear nights. I received my 3nm narrowband filters about 2 weeks ago, which I had to wait about 3 months as I wanted it fabricated to work at fast focal ratios down to f/3 (due to the bandpass shift at highly oblique inciden...

WTS: Baader Stronghold Tangent Assembly [sold]
Good day to all, I'm looking to sell my baader stronghold tangent assembly, which allows micro adjustments to be made for loads up to 7kg in piggyback mounting.
