Astrophotography

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. Technical data Exposures 15x900 seconds Main equipment (photographic): TS ED-APO 90/500 mm (3.5" FL 5.5) with QHY9M @-30°C Filter: Astrodon H-alfa 6 nm  Guiding: Celestron 102/660 mm with Atik16ic, filer UHC Mont: EQ-6 Pro with EQMOD Stacking: DSS Processing: black point adjustment. Still needs more exposures but I'm running out of good weather :-(

Rosetta Nebula H-alpha version Main optics: TS ED-APO 90/500 mm with QHY9M @-30°C Filter: Astrodon H-alfa 6 nm, Filterwheel StarlightXpress Guiding: Celestron 102/660 mm with Atik16ic, filter UHC Mount: EQ-6 Pro with EQMOD Stacking : DSS, white and black point correction, small noise reduction. exposures. 36x900 seconds

Jellyfish Nebula - H-alpha version Exposures 17x900 and 16x1800 seconds Main system: TS ED-APO 90/500 mm with QHY9M @-30°C filter Astrodon 6nm H-Alpha Guiding: Celestron 102/660mm with Atik 16ic and UHC-S filter Baader Mount: EQ-6 Pro with EQMOD Stacking: DeepSkyStacker

Orion Nebula - H-alpha version Exposures: 18x900 sec Foto: TS ED-APO 90/500 mm with QHY9M @ -30°C, Astrodon 6 nm H-alpha filter Guiding: Celestron SLT 102/660 mm with Atik 16ic with UHC Filter Mount: EQ-6 Pro with EQMOD Stacking: DSS

SH2-232 H-alpha version RA = 05:42:30.0 DEC = +36:10:59.9 Exposures 31x900 sec Equipment Foto: TS ED-APO 90/500 mm cu QHY9M @-30°C Filter: Astrodon H-alfa 6 nm Ghuiding: Celestron 102/660 mm with Atik16ic, filter UHC Mount: EQ-6 Pro with EQMOD Stacking: DSS  It seems to me that in the middle of this nebula there is a second one, it looks like a planetary nebula to me but I'm not the expert in this area.  It is also visible on the image from the Nasa Sky Survey so is not sensor artifact or optical error

Hearth Nebula - H-alpha version After sime time I managed to get online again. I "attacked" this time this object again, I have imaged this one with a Kodak 1602E based camera. Technical data: Exposures 22x900 sec Filter Halpha 6 nm from Astrodon Optics: TS ED APO 90/500 mm Imager: QHY9M at -30°C Mount: EQ-6 with EQMD Guider: Atik 16IC Image is corrected using darks, flats and bias using DeepSkyStacker, the result was imported in PS and some minor adjustments have been done (mainly curves and a little sharpening).

Somehow a second run, I have managed to get the lights in December but only now to process them. Object: Rosetta Light: 10x900 sec UV/IR cut filter stacked together with 10x900 sec H-alpha 6 nm Astrodon Camera QHY9M @ -25°C Optics: TS ED 90/500 mm Guiding: Celestron 102/660 mm with ATIK 16IC and UHC-S Baader filter Stacking: sigma clip, white and black point corrections. Mount: EQ-6 Pro with EQMOD
