  1. Here's my first attempt at a wide field from last night, this cygnus taken on an unmodded canon 550d with a Sigma 30mm 1.4 lens, mounted on an EQ5 pro and guided with a finder guider with a QHY5v. Consists of 12 x 180s @ f2.8 & iso400, stacked in Nebulosity and finished in CS6. There's a fair bit of coma in the top left so any tips on development would be appreciated. Thanks

  3. I dont normally image galaxies as I live in a Red / Yellow Zone and I find that its very difficult to achieve a pleasing result. However, I have been seeing lots of images from the ASI071mc and QHY168c cameras from highly light polluted locations achieving good quality with large numbers of short exposures so I decided to give it a go with my cooled 550D which according to 'sensor gen' has a lower read noise than either of the two pro cooled cameras when used at high ISO. As such this is very much an experiment for me as I would normally move away from 5 - 10 min exposures at ISO800. This is 230 x 120s exposures at ISO 3200, taken over three nights from my home observatory, 130PDS, Astronomic CLS clip, HEQ5 guided. 1) 60 on 8/12/17 2) 40 on 11/12/17 3) 130 on 15/12/17 Calibrated with FLATS only. As I dont normally image galaxies and so I am not very practiced at processing, this is my 5th go starting from scratch. I had to change quite allot of how I process from my normal emission nebula work flow. This is also my first use of Astro Pixel Processor as part of my 30 day trial. DSS was just not cutting it for this and I wanted something with a good tool to remove gradients. Thanks allot for looking, any pointers / comments good or bad welcome. Adam.
  4. Here's an image that i just finished processing after finding the lights that were taken months ago on a memory stick that i was emptying and had forgotten about, only had the lights so took some darks this morning by using the chip temp shown in images taken via Backyard Eos. I reckon there's 19˚c between ambient and full speed on my 550d so put it in the workshop with the heating off and seemed to match them well. Needs some more data and my processing is all that but I'm quite happy with it for a surprise find. This image was taken with a Skywatcher 200p, Heq5 Guided via PHD Canon 55D unmodded, Backyard Eos 24 x 180s Lights @ 1600iso 19 x 180s Darks only (taken months later by matching chip temp) Processed in Nebulosity, CS6
  5. Hi Guys, Off late I had been trying to find ways to fire my DSLR from my laptop and downloaded a couple softwares. Yesterday i felt like doing astronomy while it was raining cats and dogs outside, so to make up for it I simply opened nebulosity v3 and found that my camera is listed. Additionally I found that it could be binned 2x2 and 1x1. I hope to make use of this feature after skies clear. Down here the southern milky way is quite high up in the sky during the summer months. Has anyone used the bin feature through any such software? Any advice would be good. Thanks and Regards,

    M27 First on the Heq5

    From the album: Sulaco

    M27 first attempt with only 9 x 180s @ 400 iso and the same in Darks sw 200p mounted on HEQ5 guided with QHY5v and PHD
  7. Season greetings! Got my 80 Esprit around one week ago and yesterday was the first clear-ish night since. I came to my parents' for Christmas and here the skies are much better. I went to a hill nearby where our galaxy was visible. I had an EQ5 which I didn't polar align very well. I tried to start my RPi3, but it didn't connect to my mobile router so I had to forget about it. I was limited to 15s or 20s subs. The scope is quite heavy, heavier than I expected, it doesn't balance well with a Canon 550D attached. I had to tighten its dovetail towards its end as much as I could and the setup was still camera heavy a bit. Anyways. I left it to cool for maybe half an hour and it didn't reach thermal equilibrium perfectly. Focuser is very good, no slip with the DSLR and tightening it doesn't shift focus. No tilt either. I bought my scope from FLO and checked by Es. Here are some pictures taken through it, I only had the camera, no visual stuff. M45 is 151x15s: https://drive.google.com/open?id=1CbAuNQCGkQPSsPB11UOBkye3Y8EnzNDL M42 is 14x20s: https://drive.google.com/open?id=1dVgAxK8LQ4jXqPDlv2G0CVjV88UnsU9u M37 is 10x20s: https://drive.google.com/open?id=1iITFwXffhGvAi4dUbE_qR9_9VQVJszPT All ISO1600. Darks and bias, no flats. Today are exactly 2 years since I took my first astrophoto. Quite some progress since then. Clear skies and happy new year! Alex
  8. I keep "upgrading" my older pics and it actually turns out better then i thought it would... I first captured Orion RGB on the 7.3.2014 with the moon really close by (18x150sec@ISO200). Later that year i added the running man with RGB data from 26.12.2014 (11x120sec@ISO800), and the pic instantly looked "more complete". Then here a couple of weeks ago i was able to gather 20 min of Ha data (10x120sec@ISO3200]. Not nearly enough with my unmodded 550D, but helped a bit still. It's my first attempt in HaRGB, so i'm quite pleased with. Edit: First is HaRGB, 2nd is the old RGB.
