  1. Very nice work guys. When I take a close look at the first full size version; there is a very small grain background noise present? I would have thought the very long exposures would have removed all the background noise? Or was this artificially introduced during the processing? Pieter
  2. Nice overview of thge area Martin. Possibly something went wrong assembling the mosaic? The area above the "eye" in the Pelican does not look correct to me? It seems like the same patch is cloned a couple of times? There is a bright star just above the "eye" of the Pelican which does not show on your image, check some reference images of ic5070. I imaged the area myself this week, otherwise I would never have noticed, but great shot in any case! Regards, Pieter
  3. hehe, news travels fast in astro land... . I got a 150 euro discount on a 2" Astrodon 5nm filter last week (the plastic case had a small crack in it) so that I could not resist! It is still a very expensive filter but I also sold my HA 7nm and RGB filters to break even. I don't plan on doing much RGB from now on, since I always seem to prefer my mono versions anyway. Pieter
  4. Thanks for the comments, perhaps I should add another night of data. Even with HA the blazing moon did make the subs pretty noisy. Pieter
  5. Hi everyone, After months of clouds it seems, I finally had 2 nights in a row this week to finish this H-alpha project. LBN292 is a bit of the beaten track of imaging targets in Cygnus, although I don't see any reason for that. The image was exposed for 7 hours with 1200s subexposures over 3 different nights. It was the first image using a new homemade off axis guider, the TS OAG 9 proved to be too flimsy for my imaging train. Telescope: Custom 10" Newton f/3.8 Mount: Mesu 200 CCD: sbig st800 with homebuilt off axis guider Filter: Baader 7 nm. Med size here: http://www.astronomie.be/pieter.vandevelde/deepsky/lbn292med.jpg Comments welcome and thank you for checking out my image. Pieter
  6. Great work! I like the b/w rendition very much, reminds me of the old E.E. Barnard images. 30 panels with an 11 meg ccd? Did your pc not catch on fire processing this? Pieter
  7. Epic piece of work! You surely have your astrograph working to the fullest potential! Just out of curiosity: Can you see any variance in the brightness of Hubble's V1 Cepheid, since the image was stretched over several months? Again, great work. Pieter
  8. Looks excellent, well done Maurice! Pieter
  9. Thanks everyone for your kind comments! Pieter
  10. Hi everyone, 2 weeks ago I joined Maurice Toet (http://www.dutchdeepsky.com) for an imaging week in Southern France. Although we did not have the best of weather, I managed to collect enough photons to complete my M101 image. The image was made with a 10" f/3.8 Newtonian on a Mesu 200 mount, the total exposure is about 23 hours. The h-alpha data was acquired from my very light polluted home location. Please refer to my website if you are interested in more details.

  11. Hi Maurice, I knew this was going to be good and it most definitely is! Very original composition too. Looking forward to your other results! Regards, Pieter
  12. Anna, You have done incredibly well with this image! The processing is absolutely flawless! Pieter
  13. Hi Olly, I see you finally got a good mount for your tandem setup, looking great! I am sure it will work great. Pieter
  14. Great shot Yves, considering the circumstances. Yesterday had about the worst seeing I have ever seen. Look like a very nice setup you put together. Pieter
  15. Great work on a difficult object Do you credit the astrodon L filter for cutting through light pollution that well, or did you use an extra LP filter? Regards, Pieter
  16. Sara, This is looking mighty fine, congratulations. You have captured the ambience of this beautifull deep sky object wonderfully. I prefer B/W images like this, many times over the narrow band "colourbook", but that is personal taste I guess. Pieter
  17. Thanks, same to you! Mark, The reason for this is the ccd is monochrome. Most astro ccd are monochrome and colour is gathered by exposing though RGB filters. Imaging in RGB is hopeless from my light polluted sky, so that's why I image with an h-alpha filter which has a very narrow bandpass in the spectrum and is not affected much by LP. For good RGB data you need good skies, which I don't have unfortunately. regards, Pieter
  18. Thanks all for your comments, much appreciated! Now there's an idea! Hope my neighbour agrees as it is his tree. Pieter
  19. Hello all, Here is my latest image I would like to share, the Horsehead nebula in Orion. Last week I had 2 clear nights in a row which is very unusual down here. There is a huge tree south from my location so I had to interrupt the imaging session for 2 hours in the middle of each run. Hopefully I can add some more data to it soon... Scope: 10" Newtonian f/3.8 Mount: Mesu 200 ccd: sbig st-8300 -20°C exposure: 6.5 hrs through 7nm Baader h-alpha filter Med size resolution: http://www.astronomie.be/pieter.vandevelde/deepsky/horsehead_small.jpg Higher resolution can be found here: http://www.astronomie.be/pieter.vandevelde/deepsky/horsehead.jpg Thanks for checking it out & clear skies! Regards, Pieter
  20. Great shot. Did you use a coma corrector for this? Telemark? As in Telemark Norway? Lovely place. Regards, Pieter
  21. Thanks! I still remember taking my first image of M57, over 10 years ago, with a home modified webcam like it was yesterday. Still my personal favourite! That's a meteor, I really need to check a database to find out which one it is. Any ideas? Best Regards, Pieter
  22. Thank you for the kind comments; Yes I took the mount with me; I have it on a Berlebach Planet. It is at the limit of being portable, but the mounting is rock solid. Thanks Olly, I forgive you. There is always next time! regards, Pieter
  23. Hello everyone, Last weekend I have found some time to process one of my images (well the only image...) from my last astro holiday (beginning of October) in Southern France. Unfortunately the weather did not cooperate much, so nearly all of the data got scrapped. The plan was to make a 2x2 mosaic of the Pleiades, but the clouds did not seem to agree with that idea... That explains the odd framing and short exposure, but I will try to finish the mosaic next year. Exposure was: L 90 min RGB 25 20 25 (5min subs, colour binned 2x2) CCD: st-8300 Scope: Homebuilt 10" f/3.8 Newtonian Mount: Mesu200 Taken: October 9th 2013 from Provence Higher res here: http://www.astronomie.be/pieter.vandevelde/deepsky/M45%202013%20med.jpg Thanks for looking! Best regards, Pieter
  24. Jonas, That is a remarkable image, your processing is perfect. Did you use PixInsight on this? I have seen many overprocessed images done with PI that end up looking like paintings instead a pictures. But none of that here! Great scope too! Why only 3 min subs in lum? Best regards, Pieter
  25. Jonas, That is a very detailed and deep image. When I look at the full size image I can't help but notice your stars are not 100% round. Perhaps your primary mirror is pinched and needs to breathe a bit more in the cell? But great image in any case. Pieter
