  1. I imaged this target on Wednesday night having a bit of a experiment with exposures in narrow band in the past with my ccd camera ( QHY9m ) I needed 15 or 20 minute subs so with my new CMOS camera a QHY294m pro I first tried a run of 10 x 180 in each filter then a run of 600 sec subs I think I need at least 10 minute subs anyway I have combined all the data to give a Hubble palette image. Ha 10 x 180 + 8 x 600 Olll 10 x 180 + 8 x 600 Sll 10 x 180 = 8 x 600 QHY294m Pro 1x1 ( 47 mp ) TS 65 scope Bob
  2. This is my first light with my QHY294m pro at 1 x 1 ( 47 mp ) imaged on 30-10-2021 colour processed in PS I am going to try colour masking in pixinsight to see what the difference is if I can. Ha of 20 x 300 astronomik 6 nm filter Olll of 10 x 300 astronomik 6 nm filter Sll of 10 x 300 astronomik 12 nm filter QHY194m pro camera T S 65 scope
  3. Thanks Adam it is a bit short on data I hope to add to it if I can. Bob
  4. This is a LRGB image not a lot of time on it yet Luminance of 13 x 300 un binned RGB of 5 x 300 each binned 2 x 2 WO 90 scope QHY9m camera Bob
  5. This is the first light with my new QHY294m Pro camera still finding my way with setting / software and hardware only flats applied Imaged on 07-09-21 Luminance of 14 x 300 RGB of 6 x 180 each camera 11MP mode Scope TS 65 Bob
  6. Imaged over two nights 07/08-09-21 Luminance of 13 x 300 un binned RGB of 5 x 300 each binned 2 x 2 WO 90 scope QHY9m camera I think this one will benefit from more data Bob
  7. I had first light last night with my new QHY294M camera and collected LRGB data but when I tried to stack align etc in Image Plus which I have used for other older QHY cameras for years it couldn’t manage to go through with the data as these image files are a lot larger I was thinking this could be the problem has anyone any advice ? Bob
  8. I imaged this spiral galaxy over two nights 14/15-04-2021 Luminance of 36 x 300 RGB of 7 x 300 each all binned 2 x 2 scope Celestron 11" with a F 6.3 FR camera QHY9m Bob
  9. Thanks for that Chris I thought I had missed something with the mirror lock I have been imaging with mine for about eleven years now and it is a struggle at times to keep focus but I now watch all the subs coming in and if the stars seem to go out of focus I do a refocus. Where as I have another set up with a 500 mm FL refractor on a equatorial Mount and it just runs all night with no need to refocus. But for all the problems with long focal length imaging I do like to have a go at the tiny targets. Bob
  10. Thanks Chris for your feed back. I have found in the past that the blue is usually the one with a problem with the Celestron it just seems to effect the brighter stars. You said that your mirror was able to be locked I thought only the Meade scopes had this facility I would be interested to know how you did it was it a DIY job ? I have imaged at F 10 for a few years now but it is difficult to get he right conditions in the UK that is why at Focal lengths of 1764 mm and 2800 mm with the 11” I now bin all my subs 2 x 2 which seems okay for me. Bob
  11. Thanks Chris I suspect the touch of blue at the top of the stars was maybe slightly out of focus blue data when processing the RGB I did think I should have refocused in some positions of the sky with the SCT the main mirror does move during imaging. I was imaging another target last night and I did refocus and those stars were a lot better so maybe that was my problem ? Bob
  12. This image was captured over two nights 11/12-04-21 Luminance of 32 x 300 RGB of 6 x 300 each all binned 2 x 2 scope Celestron 11" with a f 6.3 FR camera QHY9m Bob
  13. I imaged these two Spiral galaxies on Friday night could have done with a bit more time on them. Luminance of 29 x 300 RGB of 6 x 300 each all binned 2 x 2 scope Celestron 11" with a F 6.3 FR camera QHY9m Bob
  14. Thanks for the reply. I have never had an issue with PHD1 but like you have said maybe I should move up to PHD2 I think I will set it up as there is no imaging possible at the moment and see how it goes. Bob
  15. I was thinking of buying the QHY294m-Pro camera at the moment I use a QHY9 and use Nebulosity for image capture along with PHD 1. The question I need answered before I buy the new camera is could I use Nebulosity and PHD 1 for imaging I have had years of using Nebulosity and PHD 1 with no problems and am a bit reluctant to change to say NINA and PHD 2 as if it’s “ not broke then don’t fix it “ has anyone any advice ? Bob
  16. I imaged this on Sunday night 21-03-21 Luminance of 33 x 300 RGB of 5 x 300 all binned 2 x 2 scope Celestron 11" with a F 6.3 FR camera QHY9m Bob
  17. Thanks for the comments Francis and Gerr I tried imaging this target the week before but had poor skies and only managed to get 5 x 300 subs after a quick process it didn’t look a very impressive target but it was in a good position so I thought I would give it another go this week and found it to be a good face on Spiral galaxy. After I got my LRGB data and processed it I could see what I thought maybe it could benefit from some Ha data that’s why I have attached both images with hindsight I think I should have toned down the Ha content a bit. Bob
  18. On the 14th of this month I went for a Spiral galaxy not often imaged NGC 3631 in Ursa Major and got Luminance of 8 x 300 and 10 x 600 and RGB of 5 x 300 each all binned 2 x 2 . I checked this one out and it said there was some Ha in the spiral arms so on the 16th I got Ha of 5 x 600 and 9 x 900 binned 2 x 2. I used my Celestron 11" scope at F 6.3 and my QHY9m camera. I have included both the LRGB and the HaLRGB images. Bob
  19. Nice capture on a difficult target.
  20. Thanks Wim, I did want to get more data on this target as like you said when I looked at the first sub NGC 2805 hardly showed up but when the subs were stacked I was surprised how well the galaxy came out I hope you manage to get your data soon. Bob
  21. Thanks it turned out a better target than I first thought maybe I can add some more data to it if the skies ever clear ?
  22. I managed to get a bit of imaging time on Tuesday night and went for this group of galaxies Holmberg 124 in Ursa Major I would have liked a bit more data but the clouds rolled in. Luminance of 33 x 300 and RGB of 5 x 300 each all binned 2 x 2 Celestron 11" scope with a F 6.3 reducer QHY9m camera Bob
  23. I was out imaging tonight and tried out the lens again I noticed before hand that the lens had a HOYA HMC UV filter on the front of the lens which i removed and the frames from tonight were perfect so that has been my problem i bought the lens second hand and did not notice the UV filter. Thanks for the help . Bob
  24. Hi Sean Thanks for the comments. I have had the QHY8 Pro since 2010 when I moved from a DSLR to a ccd I have found it a great camera I use it at -18 C and use the QHY driver at 1 - 140 hope that’s useful info. I used no filters and the adaptor is a one supplied by Modern astronomy which gives a good level fit between camera and lens. Hi Typo Thanks for the feed back. Your image shows a lot less aberrations with me just trying the lens out to get focus I had to turn the setting from infinity to further down F settings on the lens I wonder if another spacer ring were to be added it would then enable me to get closer to the infinity mark on the lens when achieving focus and this may give me less aberrations ?
