  1. From the album: Deep Sky Imaging

    This is the SHO result of my first imaging object with the cooled Canon 40D. Through out the imaging, the camera failed a number of times due to condensation buildup inside and so this is a result of two different 40D bodies and sensors. I captured some HAlpha data with the originally cooled 40D before it failed and the second half of the HAlpha, OIII and SII are captured with the second modded and cooled 40D    Exposures: SII: 30x1200s HII: 30x600s OIII: 30x900s ISO1600 Telescope: BOSMA Beta RE  Focal length: 500mm

  2. Hello all, I just got the O3 and the S2 filters this weekend after 2 months of waiting. I bought initially an Optolong Ha and I thought to buy the O3 and S2 also from Optolong. They O3 and S2 are advertised as being 6.5nm which also contributed to go for them instead of the Baader's. Anyway, I acquired some 3 hours if I remember well with the Ha in 1min subs and now just above 2 hours with the O3 in 3min subs. Unfortunately, I can image to the south only up to ~130 degrees in AZ. So the good skies around 180 degrees where objects reach the max altitude are not reachable from home. I have to give it a try later in spring from outside. All taken with the ASI 1600 MMC, cooled to -15C, put on the Tair3s wide opened at F/4.5. 300mm focal length. https://drive.google.com/open?id=0ByhJ_xuQxcnjWUZUZTRyRXFYYzA Will post in the evening the Ha and the O3 components which were mixed HaOO. Clear skies, Alex
  3. Good evening all, It's been a while. Here's a quick Rosette for you, a work in progress...

  5. evening all. while observing a few clusters tonight i come across ngc 2244 ,the o/c in monoceros. i used a refernce book to confirm the star pattern .so then i realised im sat smack in the middle of ngc2237,the rosette nebula,so i sat and observed for ten to fifteen minutes to see what i could temp out. NOTHING is the answer . i was abit gutted at first,but after researching a little on the forums i realised its a tough one to observe. and theres me with my orange sky glow unfiltered roof top infested sky ! what was i thinking.
  6. I imaged the Rosette Nebula using my Ha filter the other night. It looked great Problem was my FOV was too small. I have SGP with Mosaic so thought I would give it a try and also get some sleep in the process. Last night was a great night for inaging. Very clear and dark here after moonset. I decided to image with just a LP filter. I set SGP to take a 6 panel image using 10x 120s subs for each panel. Taken at f/2 using C11 Hyperstar and Atik4120EX OSC on Mesu 200 mount. The top of the image looks like frost or cloud may have got in the way. I will take a look later. But so far I am impressed with the potential I have reduced the file to 1.6M from 100M I will attempt some panels again on this subject. Also I will do again in just Ha to see the difference. Thanks for looking.
  7. At the moment it feels like I am juggling too many balls. I have quite a few images waiting in the wings as it were to be processed, but no time to do them justice, but still they come, as at the present moment M109 is rolling off the camera. So I thought I'd post a couple of previews of stuff in the pipeline. All at long focal length and perhaps a bit different to a standard offering. None of these images have been calibrated, just taken the lights and stacked them, and with M76 combined the Ha and O3 data to see how it looked. Just basic processing. All images taken with C11EdgeHD and Atik 428ex, with 7nm Baader Ha filter. Binned 2x2 usually. Thanks for looking, let me know what you think Tim
  8. I set up yesterday despite a bad forecast to try and fix a cabling and power issue, as the night drew in I noticed the clouds starting to clear a little so stayed setup. In total managed about 2 hours of clear imagining - a lot of the subs I took though were pretty dire - I think in reality whilst it looked clear to the eye there was a lot of moisture in the air, and maybe some high cloud too. After calibration I was down to 10 good subs of 180seconds. Decided to quickly process it today to practice, a few tweaks to reduce smaller stars (I prefer the look slightly) other than that I havent done too much - will wait for more data. Im just so happy the clouds cleared for a while, I had to share!
  9. From the album: Deep Sky

    Reprocessed to try to reveal more of the fainter nebulosity. 22x5min Canon 450D + Baader 7nm Ha filter
