One more Messier object for my catalog đ M92, nothing spectacular, but further a good test for my new Bahtinov mask. Details
First light for my new Bahtinov mask. I’m very happy with it. Much sharper result than the last M57 image. This time at f/6.3, ISO800 and only 60sec. M57 is a planatery nebula. 2300 LY away from Earth. The nebula emissions contains expanding and glowing ionized gas, expelled from red giant stars in the last […]
My first Bahtinov mask was for the Canon EF 200mm f/2.8L. On the EF 400mm f/5.6L, I had always problems to recognize the typical pattern in LiveView mode (10x). And in the last few months my images were sometimes a little bit out of focus… So I decided to buy a new Bahtinov mask for the Canon EF 400mm. It’s a Gerd […]
This tutorial is for the old PixInsight version 1.8.5. Click here for the latest PixInsight version 1.8.8-7 tutorial. After posting my recent M57 image on Astrobin, I received a feedback regarding Drizzle (thanks Marcus!). I never drizzled before since I thought it’s very complicated… It is not! Drizzle was originally developed for the NASA’s Hubble Deep Field […]
Again the Moon at 560mm. Stacked in Fitswork, processed in PixInsight. Canon EOS70Da, Canon EF 400mm f/5.6 @ 560mm f/14 (Kenko 1.4x converter), 18 x 1/500s, f/14, ISO400 Astrobin This time the result has much more sharpness than the previous one. Manually focusing is better đ Previous shot September 17, 2016:
To stack 41P comet I used for the first time PixInsight. Unfortunately (or fortunately?;-) DSS failed to select the comet on a single frame, so I switched to PI. Finally after several hours try & error and many tutorials I was able to manage the comet. See here the used processing steps: Comet Processing […]
Finally on the sky, M57 Ring Nebula đ First time at 400mm. I’m happy with the result but 400mm is to short. Details Drizzle 2x integration: Normal integration:
Exactly 2 years ago I created this blog and posted my first image. Because of this “birthday” my tought was that I’ll share something with you. Maybe someone of you are interested to see how my acquired raw material looks unprocessed⊠so here is a little present: Give Away Download Rosette Nebula raw files package. All files directly […]
First, there are 2Â possibilities for a comet animation: Static comet or static stars. I’ll show here both ways since they are very similar. Note: these are very quick processing ways. They are surely improveable đ Static comet Run BatchPreprocessing Open Process – CometAlignment with registered images (c_d_r files can be found in subfolder “registered” […]
Distance from earth around 24,5 million km, estimated coma diameter 134’000km, speed 37km/s: Comet 41P/TuttleâGiacobiniâKresĂĄk Of course I created an animation đ 56 frames (400mm, 150s, f/5.6 ISO1600) Date: 21. April 2017 Time: 21:45h – 00:17h CEST See here how I created the animation. YouTube
