  1. Hello there StarGazers or shall I say CloudGazers! Hahahaha! I'm sorting out an auto guiding rig for when the clouds vanish eventually. I'm using the Raspberry PI Model 2 with Lin_guider. I'm after either the following CCD's: QHY5L-II Mono or ZWO ASL120MM Mono Let me know if you have any spare or have recently upgraded. I was going to go with an Altair Astro mono GPCAM but currently there is no support from lin_guider or Linux drivers as of yet. Thanks all!
  2. The veil Nebula, one of my favorites! I've previously captures this one, but felt i had a lot to improve. This is another attempt on capturing it and consist of a good mix of data captured over several nights. Finally i feel like i'm starting to get somewhere with this target! It's all captured with the QHY5L-II-M camera, unguided with a 50mm F/1.8 and a 135mm F/3.5 lens. Both are old manual Olympus OM lenses. Exposure: 10x 10 min OIII - 50mm F/1.8 (edit: F/2.8, not 1.8) 15x 10 min Ha - 50mm F/1.8 (edit: F/2.8, not 1.8) 4-part mosaic, total 254x 2 min Ha - 135mm F/3.5 Total exposure is 12 hours 38 minutes. Mainly it's Ha exposure though, and i'm looking forward to capturing more OIII as well at a longer focal length - but for now i'm really happy with the result!
  3. While i was indeed satisfied with my HaRGB picture of M27, i couldn't resist giving a bicolor a go as i only needed some OIII data. Taken with the QHY5L-II-M and the Explorer 200. Camera cooled, i can't remember exact temp, but i believe around -10c. 7nm Ha: 47x 60 sec, gain = 1000 in firecapture 8.5nm OIII: 60x 60 sec, gain = 1000 in firecapture
  4. It was only nautical dark in the nights here in Norway when i took these, but gave narrowband a try with my QHY5L-II-M anyway, and the results are not bad at all for such a camera i think. It's noisy, but i guess with this little data and a planetary/guide-cam i guess that's to be expected. With more time i think it will give decent results. Taken with the QHY5L-II-M cooled to around -5c and and Olympus OM 50mm F/1.8 lens at F/2.8 OIII 8.5nm: 10x 600s with gain at 20. Ha 7nm: 15x 600s with gain at 12 (i think). No darks, flats or bias.
  5. Back in 2013 i captured a nice image of this nebula that i was very pleased with. However, it strongly lacked red as my unmodded 550D filtered it all out. So here the other day, trough some fog, i managed to capture some Ha data with the help of the QHY5L-II-M and a Baader 7nm Ha filter with the explorer 200. Exposures were limited to only 60 sec as i was capturing unguided, and even then i had to throw away half my subs (i really need to have my mount chacked and serviced...). Captured using Firecapture, with gain set at 1000, and peltier cooled the camera to about -20c. RGB data from 2013: 1 hour 45 min @ ISO800. Ha data from this week: 47x 60 sec. Gain 1000. I think the Ha data helped a lot to bring out more red color and details. What do you guys think? Original RGB from 2013: Ha data from the QHY5L-II-M: New HaRGB:
  6. Selling my as new QHY5L-iic colour camera, bought last summer for £159 to use with my 127SLT and literally used two nights since, about 20 minutes worth of video. After having 2nd child I've just not had time to use my astro gear so it will all be for sale over next few weeks. Item is in its original box and all accessories and obviously in pretty much new condition. Asking for £99 plus delivery but open to offers. Collection from Belper, Derbyshire welcome.
  7. Hi all This is my first attempt at imaging the moon with my QH5l (Planetary Webcam) I took about 2000 raw frames at 14bit through my 80ED with a 0.5FR (to get the moon into the frame) I have stacked at 25% in AS!2 and done minimal wavelets and RGBautoalign in Registax. I have played a bit with the gamma and midtones via filters to try to even out the brightness. Rotated moon and placed against a black background and reduced the size for this forum. Any advice as how to reduce the bright spots without loosing the detail. Or is this what it is supposed to look like?
  8. I know that a QHY5 is a pimped webcam, but it is not a dslr or a CCD. So I am a bit over imaging Jupiter for now, so I turned my attention to the moon. Anyway enough waffle, with out further adduce my first attempt at lunar stacking. What do you guys think?
  9. From the album: Moon

    This was taken last night at about -4C in 12bit Raw format with 2000 images and a 25% stack. Debayer and Stack in AS!2 and some RGB and wavelets in Registax. Lastly I placed the moon on a black background and positioned it to make a nice desktop image. Enjoy

    Have had a play with the 3x Drizzle
  11. From the album: Saturn Journey

    First image of Saturn taken at 6:30am on the 5th of Jan 2014. Second round of processing, this time I have created a luminance layer and enhanced with a Blue Filter.
  12. Hello Please find my first attempt at Saturn. Advice needed on how I can improve capture and processing. My adventure started at 6:00 am this morning taking on -2C ice and frost, to capture Saturn in the South before sunrise. The transparency was good though and the stars looked really crisp against the still dark sky. (Exciting!) I managed to capture two run of 39000 images at 65FPS at 15ms exposures, raw mono data. Using my 127mm Mak (1500) with a 2x Barlow to get it up to 3000mm Anyhow just finished processing, process followed was. (Was done in a bit of a rush.) Dark Frame 10000 stack at -2C Reference Frame AS!2 - 25% using 4 quality setting, sharpening and mix in raw 50%, REGISTAX - Wavelets and gamma adjusted, Histogram stretched. Main Frame AS!2 - 50% using 4 quality setting, sharpening and mix in raw 50% REGISTAX - Wavelets and gamma adjusted, Histogram stretched and increase size to 1.5 I have been a bit aggressive with my wavelets and placed this on a black background, with a bit of mid-tone adjustment. It feels a bit blurry and very yellow, not much in the blue channel, is this normal? Do I need I need to up my FL to from 3000 to 4500? Lack detail for +-20000 images, should I up the exposure and reduce the images? I am being overly critical for my equipment? Thanks for the feedback, appreciate it guys.
  13. From the album: Imaging Jupiter

    First image of Jupiter for 2014. Taken on 04th of Jan, at about 4C Nice clarity on this one, transparency was excellent, but occasional clouds to be dodged.
  14. From the album: Saturn Journey

    First image of Saturn taken at 6:30am on the 5th of Jan 2014. First round of processing, will reprocess again later, see if I can improve. Seeing was poor, but transparency increased through the morning. Caught this image just before sunrise at 65FPS, got 39000 images.
  15. From the album: Imaging Jupiter

    Jupiter - EQ5Pro, 127Mak-Cas - F12 QHY5l - Colour +-1000f (1.2 Gb 1min05') -7C Pipp, AS!2, Registax6 (75% Stack, Wavelets, RGB Align, Contrast) This was taken on the 28 Dec 13 at about -7C did about 1000 images
  16. From the album: Imaging Jupiter

    Jupiter - 127Mak-Cas - F12 - AS!2 - 750 Stack - Denoise / Sharpen - Histogram Stretch - RGB Rebalance - Midtones adj This was taken on the 22nd at about 2C did about 1400 images, but due to clouds and poor seeing has been reduced to 750. I have sacrificed some detail on the planet to include the moons, think it is better like this though.

  17. From the album: Imaging Jupiter

    Jupiter - 127Mak-Cas - F12 - AS!2 - 840 Stack - Denoise / Sharpen - Histogram Stretch - RGB Rebalance - Midtones adj This was taken on the 22nd at about 2C did about 1400 images, but due to clouds and poor seeing has been reduced to 840. I read a great post which helped me a great deal in getting a better image. http://stargazerslounge.com/topic/184821-beginners-guide-to-stacking-planetary-images-with-autostakkert2/?hl=+registax (Thanks James) Going to continue processing and see if I can get this better.
