  1. Hi! First light with my QHY8L and first contact with CCD camera :-) It was a right choice and good upgrade from Nikon D7200. 13x600s - Light at -20C 25x600s - Dark at -20C 35xBias 35xFLAT Tomek
  2. QHY8L Great condition APS-C sensor one shot colour CCD Specification CCD Sensor - ICX413AQ Total pixel - 3110 x 2030 Pixel Size - 7.8um*7.8um Color method - RGB BAYER film on CCD Effective sensor area -28.4 mm diagonal QE - 60% at Green (Peak) , 50% at Blue and H.a USB -2.0 Weight -400g Ultra small size suitable for primary focus imaging and Hyperstar Price includes UK registered P&P Any questions please feel free to ask.
  3. From the album: Hyperstar and QHY8L

    Taken on 15-Dec-2017 (no moon) Hyperstar 9.25" with Baader UFC and IDAS P2 filter Avalon M-Uno guided and dithered with Nebulosity and PHD2 20 x 60 seconds Processed in PI
  4. Managed to grab a few minutes imaging last night before the clouds rolled in. Gradually getting used to using a ccd (qhy8l). My third go with it. The second go I posted elsewhere but was out of focus on one side. Anyway, here are just 7 x 60s subs of M3 stacked in dss, processed in StarTools: It's a bit noisy maybe because I ran the camera at 0 deg rather than lower. Obviously needs more photons but I'm otherwise not too unhappy with it. Louise
  5. Another quick snap from last night (15-Dec-2017), and the first time I've imaged the Christmas Tree cluster / Cone nebula. Hyperstar 9.25" with Baader UFC and IDAS P2 filter Avalon M-Uno guided and dithered with Nebulosity 15 x 120 seconds (30 minutes total) Lightly (and, no doubt, incorrectly, processed in PI) Help for improvement much needed.

    Eastern Veil

    From the album: DSO

    Eastern Veil - first light with my new (second-hand) QHY8L - and my first ever colour image. Taken on 21 Sep, 2017 @ 23:15 ~ 24:00 QHY8L camera @ -5 C Quattro 8" with CC Avalon M-Uno mount 10 x 5 minutes, guided & dithered (with PHD2 / Nebulosity) FLATS, BIAS, Bad pixel map, de-Bayer, and a bit of stretching and saturation (also in Nebulosity.) It's somewhat cropped since the CC spacing was a bit wrong.
  7. From the album: Hyperstar and QHY8L

    Taken on 15-Dec-2017 (no moon) Hyperstar 9.25" with Baader UFC and IDAS P2 filter Avalon M-Uno guided and dithered with Nebulosity 10 x 120 seconds (for a total of 20 minutes) Lightly processed in PI
  8. This is the result of my first attempt at narrowband imaging with a OSC CCD. I used the QHY8L and a Baader 35nm Ha filter (not quite narrowband - more like moderately narrowband). The image is the result of 10 x 300s standard RGB exposures with 3 x 1800s Ha exposures, binned using the 'low noise 2x2 bin' feature of Nebulosity 3, and added as a luminosity layer in Photoshop. I am a little disappointed that the outer halo didn't show up but I guess that is the limitation of using a OSC CCD with only 25% of the incoming light being captured. It may also be down to the broader bandwidth of the 35nm filter. However, adding the Ha does show up a little more detail in the nebulosity that my standard exposures, so it was a worthwhile experiment although I won't be forking out on a full set of narrowband filters just yet.
  9. Cracking night, last night (15-Dec-2017) although with temperatures a bit below freezing and gusty winds. Having discovered that the spacing for my QHY8L on the Hyperstar was incorrect by 3mm despite using the Starizona-supplied spacer, I'm now using the excellent Baader Universal Filter Cell to give me nearer to the correct spacing. Still not quite there yet, though. To check it all out I went for a number of targets for a relatively short time. Here's my go at the Horsehead. Hyperstar 9.25" with Baader UFC and IDAS P2 filter Avalon M-Uno guided and dithered with Nebulosity 20 x 60 seconds Processed in PI (shhh... I'm still learning) Haven't really got the hang of noise reduction, (and seems my bias or darks aren't handling a bad column) but really the answer is more data, and I suppose this isn't too bad for just 20 minutes... Advice more than welcome.
  10. Hello, I have not posted very often but visit the site a lot. I have owned a QHY8L CCD for just over a year and used it very rarely. After initially using it and completely failing to produce any images, I gave up and returned to my modified Eos 600D. Over Christmas I have began reading 2 books by Steve Richards, "Making every Photon Count" and "Dark Art or Magic Bullet". Revisiting some of my Eos data I am making a small amount of progress improving the processing. I really want to master using the QHY8L and have looked at some of the previous data I have gathered. Previously I had no discernible image and now the image I have is awful but there is something there which is a step forward for me. The main thing I have noticed is the "Rings" of varying brightness. My question is could this be caused by the spacing of my QHY8L to my Reducer/Flattener. All feedback is genuinely appreciated I would love to produce an image from my QHY8L this year. Thanks Andy
  11. It has been a long time since I last posted on here; primarily due to a change in job that keeps me away from home during the week and a clear sky during my weekends at home has been a rare event in deed. However, the recent planetary alignment has obviously brought me luck, as a combination of being at home and having clear skies, stable atmospherics and no moon finally provided me with an opportunity to fully test the potential of the Altair Wave 115 ED Triplet Refractor, combined with the Planostar 0.79x Reducer/Flattener - and boy was it worth the wait! I wanted to compare the results to my previous scope - the extremely capable (in my humble opinion) Sky-Watcher Explorer 190MN Pro Mak-Newtonian Astrograph. So I chose one of my all-time favourite subjects - M42, the Great Orion Nebula and Running Man. The image I captured using my 190MN was the first of my own astro-photos that made me go wow! The image comprised of 10 x 300s, 10 x 200s and 25 x 45s exposures, captured using a QHY8L and Nebulosity 3 then processed using Photoshop CS6. The final result is now framed and has pride of place on the wall above my desk. I was convinced it was going to be hard to beat. My previous attempt at M42, using the Sky-Watcher Explorer 190MN Pro Now, before I compare the images I must point out that this is not going to be a direct, scientific comparison. For a start, there are a couple of significant differences between the 2 scopes; FOV being the most obvious, with 1.35° x 0.9° for the 190MN Pro, vs 2.13° x 1.42° for the 115ED with the 0.79x Reducer/Flattener fitted. The aperture being another significant difference, with the 190MN Pro being 65% larger than that of the 115ED. The 190MN Pro is also marginally faster, with a Focal Ratio of 5.3, vs 5.53 for the 115ED. However, I did use the same QHY8L CCD camera to capture the image and the NEQ6 mount and Lodestar XPress guide camera were also the same. In an attempt to compensate for the smaller aperture and slightly slower Focal Ratio, I increased the length of the exposures to allow as much light to reach the camera's sensor as possible. The final image, which you can see below, is the result of 14 x 600s and 15 x 30s exposures, captured using the QHY8L and Nebulosity 4, then processed using Photoshop CS6. Some may say this is an unfair comparison, but all I wanted to do was see if the Altair Wave 115ED was capable of achieving similar results to the Sky-Watcher Explorer 190MN Pro. The answer is yes - definitely! But that is my opinion - let me know what you think. My latest version, using the Altair Wave 115ED and 0.79x Reducer/Flattener
  12. Hi all, Normally when I plug my QHY8L into its power source the fan starts whirring straight away. But last night this didn't happen... and I couldn't get the fan to work at all. The camera itself was still responsive, i.e. I could image with it, but with no cooling... I tried two different power sources; ensured that the cables and connectors are firmly in place; and the various LEDs are lit up as expected. So I'm a bit puzzled. Any ideas on what could have happened and how to fix it? I'm probably missing something obvious.
  13. A couple of shots taken last week. WO FLT 98 APO, EQ6PRO,QHY8L,IDAS LP, FF/R TV 08X. M45 - 40X600SEK Double cluster - 40x300sek Rosette nebula - 18x600 sek.
  14. It was a lousy night to try this: full moon and cloudy, but various bits of kit had just come together so it had to be tried... I lost several subs due to cloud, and guiding kept losing the star as the mass kept changing. Nevertheless, here is the North America nebula: 7 x 300s subs (for a total of 35 min,) QHY8L (OSC) cooled to -15C Hyperstar C9.25 Avalon M-Uno mount Guided and dithered (sometimes less guided and more dithered!) basic processing in Nebulosity and MATLAB Because of the full moon, there were some horrendous backgrounds to deal with, and I don't think I've done that too well. Also, there's been absolutely no tweaking of the Hyperstar/QHY8L combination, but it's a start.
  15. Hi! My second session with QHY8L. Still learning of this camera... Only 120mins because of connection problems with EQMOD but I'm pretty happy with the image :-) -12x600s light - darks - flats -biases Tomek
  16. After seeing some absolutely incredible widefield and through telescope results from a good friend in Brazil using the QHY8L this is the logical upgrade I have been considering from a modded Canon 450D. Now I do know a few SGL members have the QHY8L and I have recently seen a QHY8 for sale. Comparing the QHY8 against the QHY8L, the imaging capabilities "appear" similar, I appreciate the physical design is different. But aside from the latter, are there any other differences that would say put the QHY8L at a level above the 8 ? Searching for images of the QHY8, they are few and far between and to be honest, I have not seen any that match ones I have already seen taken with the QHY8L. Now I know the skill in bringing out the image is arguably the most important aspect on the final result but I do need to be certain I am making the right decision regarding the capabilities of the camera ..... or "Bank of wife" will kill me, again Many thanks in advance, Kind regards, Steve
