Hello Astronomers, As I'm doing more night shifts at work and so I'm getting the opportunity to process some of my back log of data on the laptop... Last night I processed my first framing of Gum53 in the constellation ARA, a total exposure of 1 hour and 48 minutes before I stopped the exposure and reframed to what I posted about a month ago. I wasn't going to spend too much time on this data but I didn't want to just delete it either, so even though its nothing spectacular, I'm still sharing the results of the rejected data. CS, MG
Close up image of Gum 53 or NGC 6188 (AKA Fighting Dragons) imaged in natural color. NGC6188 is an emission nebula located 4,000 light years away in the constellation Ara. This image was exposed with a cooled and full spectrum modded DSLR, though an 8" SCT at 2000mm focal length. The total exposure for this photo was 4 hours and 15 minutes.

Hello All, I have Good news and bad news... The good news is that the image which I'm sharing with you was one that I had doubts that it'll be anything worth sharing but turned out OK.... the bad news is that this is the last image I'll be imaging for possibly a while since on the last night of imaging SII subs, my CGEM mount died and who knows how long it'll be before I either fix it or get a new mount. I've started another topic about what happened and my suspicions of what caused it in the "Mount Discussion" equipment section here.... This is a close up of Gum 53, NGC 6188 or Fighting Dragons, emission nebula in the constellation Ara image with my cooled 40D, through the 8" SCT at 2032mm focal length. The total exposure for all subs is 50 hours and 46 minutes. There was plenty of HAlpha signal, bit less OIII but still quite strong but SII was very weak.... I had to resort to 2400 second ISO1600 subs to get any data visible... I guess imaging this object at f10 prolong the necessary exposure time. Thanks for looking, till next time, Clear Skies everyone, MG
Close up image of Gum 53 or NGC 6188 (AKA Fighting Dragons) imaged in narrowband and SHO channels combined into "Hubble palette". NGC6188 is an emission nebula located 4,000 light years away in the constellation Ara. This image was exposed with a cooled and full spectrum modded DSLR, though an 8" SCT at 2032mm focal length. The total exposure through all narrowband filters is 50 hours and 46 minutes.

Hello All, Before I imaged this nebula in narrowband, I begun with imaging the figthing dragons in natural color by gathering OSC subs through the IR cut filter. This is imaged at 2032mm focal length, through the 8" 8SE, with the Cooled modded 40D DSLR. Total exposure time was 4 hours 15 minutes in one night. Clear Skies everyone, MG
