Astrophotography

I tried to finish this object since some time but only managed to get the exposure time in the burst style. That means that per night I got 2-4 images till the clouds marched in and ruined my sessions. So here it is, at least finished after over 3 months. Mount: EQ-6 Pro over EQMOD Photo: TS ED 90/500mm 3.5"/ F 5.5, QHY 9M at -30°C -22°F Ghuiding: Celestron SLT 102/660 mm  4.0"/ F 6.5 Atik 16IC Filter: 6 nm H-alpha from Astrodon (Starlight Xpress Filterwheel 7 pos.) Exposure time: 63 x 900 seconds Stacking in DeepSkyStacker and post-processing in Photoshop. Astrometric solution RA 22h 18 m 04.8s DEC +55° 50´ 44.2" Pos Angle +89° 44.1´, Focal length 496.1 mm, Resolution 2.24"/Pixel

So, I have to do a bulk upload.. I have "ignored" my blog for some time, just had a lot of work to do with my house and job and and and. The images are done from march to September this year and the stacks are from 20 to 45 single images each 900 seconds long. Stacking have been done in DeepSkyStacker (the last beta version) with some aggressive values set for sigma-kappa clipping and it seams that I am close to the optimal setting for stacking narrow-band images. Post-processing done in Photoshop. Enjoy the images and apologies for not tagging (yet) my images ;-) Equipment TS ED-APO 90/500 mm (3.5" F/5.5) with QHY 9M at -10° till -20°C (14°F to -4°F) Guiding Celestron SLT 102/660 mm (4" F/6.4) with Atik 16IC and UHC-S Baader filter H-alfa filter: Astrodon 6 nm Mount: EQ-6 Pro with EQMOD

Hura... I just got an email from  http://www.fotocommunity.de The Horsehead and The Flame image will be tomorrow between 11 and 12 AM set as front (main) image when you will navigate to that page. Oh boy, Im so glad... Take care friends Emil EDIT 15 of April. It is there... about 900 views in 15 minutes

M81, M82 and IFN Until now this one is the hardest  project done in team with Emil Pera. In January he asked me - being done with the Rosetta Nebula - if I have some target insight, after my negative answer I got a "what about the IFN? what do you think about it?". It was more than OK for me and because I'm that kind of person that believes only what I see, I ignored the notices found over Internet like "For IFN you need a good sky" and so on. And here we are, after weeks of work, nights lost because I have used the wrong star to center and frame the objects (about 2 nights in fact) and some sweet words addressed to Lady Moon  (exposed 60x1200 sec exposures to realized that, in fact, for IFN you really need moonless nights) we managed to use 47,5 hours of data. Emil Pera 4 minutes exposures summing 12 Hours Equipment 8" Newton F/3.3 with ASA reducer/corrector, EQ-6 mount, Canon 1000Da camera and TS OAG On my side (LOL you...

NGC 2244 Rosetta Nebula in narrow-band  (Hubble palette) Nope is not my birthday LOL but it seems to me that Emil Pera starts to enjoy the work on narrow-band images so a few days ago he send me the stack of my NB images used in our project. So (drumming sound) here it is m baby :-) looks good to me! The processing is done in the Hubble palette, I'm at hospital now so in a few days I hope to do a version using the CFHT ( Canadian - France -Hawaii Telescope ) palette, in that case the Nebula will be mostly read.

NGC 2244 Rozetta Nebula First major project together with Emil Pera. Emil Pera: Newton 8'', ASA Keller corrector/reducer, Eq6, Canon 1000Da, iso 800,TS OAG. Exp: 52x3,5' + 66x4'- Nov. and Dec. 2011. Emil Kolbert: EQ-6, TS ED-APO, corrector TS 2", Qhy9M @ -30°C. Exposures: 36 x 15' Ha, 19 x 15' O3 and 28 x 15' S2 February 2012. For us it is the first 6 channel image. Total exposure time 28 hours So after long sleepless nights.... it is done, we can live now :-)

IC 405 Flemming Star I have "attacked" this object some time ago using a camera equipped with a Kodak 1602E sensor but because it was a NABG I couldn't expose enough to get the nebula as I wanted.

Still needs more exposures but I'm running out of good weather :-(
