  1. Thanks for all the nice comments. I have done some slight tweaking to see if I can make the Ha areas stand out a bit more with this one.
  2. My second image of last weekend session was M33, which I imaged before going to M42. It consists of 9 hours 20 min of data in 5 min subs at ISO800, calibrated with darks, flats and bias in DSS and processed in Nebulosity 2.5 and PS CS3 by the DLSR-LRGB method. The data was an absolute joy to process and took me not all that much time to reach a satisfactory result. hope you agree on that.
  3. So we had some fine weather overhere in The Netherlands during the past 3 weeks, and I took full advantage of the clear nights arounbd the full blood moon (which for me was eclipsed not by the Earth's shadow but by grey clouds as I live in the only part of the country that did not have a clear night during the eclipse) and shot some lovely Ha data of NGC6914 (awaiting processing) and Messier 42 during the second part of the night. The Ha data comprises 7 and half hours of 10 min subs at ISO800 with the Canon 350D/8"Newt, calibrated with darks, flats and bias in DSS and processed in PS CS3. La
  4. Thanks everybody, This is truely a joy to have such an observatory and be able to do astrophotography within the blink of eye. Now if only the weather would be a little more cooperative.
  5. After a question from one of the forum members about how everything is running, I thought it would be good to share my first 3 images made from the balcony observatory. I think the results speak for them self with regard to thermal and/or vibration issues.
  6. Here is what i build to accomodate a similar setup. This is as small as you may get it. LOMO; a Balcony Micro Observatory
  7. Thanks for all the nice comments, and it's good to be able to shoot some nice images again. I'm really pleased with the comfort of comming home from work, open the observatory and be up and running within about 15 minutes. Also thanks for pointing out the green colorcast, which is very difficult for me to observe being a red and green color blind person, and therefore having a biased color interpretation. i have to go by the histogram for most of my color balancing, and weakt color casts are always problematic if i'm not made aware of these. so I did some HLVG magic on the original image and t
  8. I has been about 18 months ago since i had imaged from my home (September 2013) and in between i had only aquired 2 images during the spring/summer of 2014, when i went camping with my family, so i had gotten a bit rusty. I build myself an observatory on my 2nd floor balcony, but when I finally got around installing all the equipment in the fall of 2014, the Dutch weather put off a serious first light for almost the entire winter. Also because i still had some finetuning to do to the alignment (and I don't like that being outside at -10°C, having to tinker woth the bolts and bits), and because
  9. So, finally a clear night without any other obligations, so spent some time on polar aligning the NEQ6 using AstroTortilla Polar Alignment tool. Despite having read some bad experiences with this tool, I have to say it worked out rather well to get my mount reasonably polar aligned without having any views of polaris from my balcony. Also using Alignmaster proves difficult as it has a preference for N-S star pairs and I have hardly any view towards the Northern skies. With a couple of itterations AT now reports my altitude error as 48' (coming from 5°) and my azimuth error was around 2-3' so I
  10. Bad luck last night,as clouds prevented polar aligning the mount. Hopefully this week will bring a clear night to do so.
  11. So, finally managed to take some images to show the latest progress. Control PC ready for action on polar algnment tonight. On the right is a simple weather station to monitor temperature and humidity in the observatory when not in use. Another view of the control unit with the imaging equipment ready for action in the background. The PC is attached to the monitor stand so it has a nice small footprint. Camera mounted, with all needed cables/hub. Finder guider and main data cable. Outdoor sensor of the weatherstation mounted on the lower casing of the observatory. In the background, some
  12. Is that a dewheater on your primary? Isn't that giving poor views due to creating tube currents from the injected heat. I know someone on the Dutch Astroforum did the same and he removed straight away as it removed the dew, but also ruined his images. To prevent dew it's better to blow away the boundery layer above the mirror with a Mauro da Lio baffle with fan.
  13. I'm in the process of downloading/installing AT right now, which also has an plate solving polar alignment function build in.
  14. That's handy if not for the fact that I have the syntrek version of the NEQ6, so no hand controler, so I would need to have someone over who has one. I'll keep it mind though as I have some friends with hand controlers.
  15. LOMO is alive. Yesterday I got around to instal the rest of the equipment and started to prepare the control PC with the much needed software. All connections between software and equipment are up and running, so I'm nearing "first light". However, before that, polar aligning will prove somewhat of a challenge as I have almost no view of the Northern sky and Alignmaster strongly favors starpairs with a component in the Northern sky. So I'll probably will also try the polar alignment help in AstroTortilla, or EQalign to perform polar alignment. Images of the completed setup will follow in the c
