  1. Seeing was fair last night, though there was a faint halo around the Moon. Still, I managed the following with the C8 at f.10 and f.15. Camera was the Altair GPcam V2. A Baader long pass 610 was also used. 200/600 frames stacked, processed in Photoshop.
  2. M92 and M81. These were imaged in increasingly lightening skies with a waxing Moon. We're really coming to the end of the deep sky season in the far north of Scotland now but I wanted to test my new cam, the Starlight Xpress SXV-H9, with the C8 at f.8. 7x300 secs for the Cigar galaxy and 10x120 secs for the globular.
  3. Ah I have the same camera. I have done some decent shots with the Altair GPcam mono that has the same chip. Again I used the C8. I only imaged this because one of my online astro friends suggested it as I was setting up. I'd forgotten about the supernova. It wasn't my original target.
  4. Ooo that'a a nice one mate! What equipment did you use? As far as the supernova, better luck next time!
  5. M100 and supernova 2019 ehk, imaged last night with the Celestron C8 at f.5 and the Starlight Xpress SXV-H9C. 7x300 secs and 3x600 secs. The supernova is the star nearest the core.
  6. Well I went up and personal on the sun this morning. AR 2741 and 2740 at 08.30 UT. Altair Astro 102 ED-R and Daystar Quark with the DMK 31 camera. But this time no reducer. I reckon one around 0.8x would be OK. Plus a quick shot in white light with the Baader photo film, continuum filter and IR blocker.
  7. A close up shot of the comet using the Altair Astro 60 EDF and the Altair Astro GPcam. 20x30 secs. I stacked the stars and comet separately then combined them in Photoshop, so no star trails. I also made a short video covering about 30 minutes. The dimming at the end is due to high cloud. https://www.youtube.com/watch?v=HJBwjZy8Vq0
  8. Two discs and a close up from August 2.
  9. I also have a DMK 31. Even that suffers from rings occasionally but by no means as bad. However. with my set up the ASI seems to give better results, which is why I prefer to use it. I also use the ASI with the Quark but in that instance I find flats (generated by a cling film cap over the objective) work a treat.
  10. Thanks Pete. I read a post by Mark Townley over at Solar Chat in which he mentioned the possibility of using an ADC. I must admit I'd never thought about it. I needed to screw the camera directly into the ADC and add a barlow lens (which I do anyway but now it's further from the chip giving me a slightly larger image scale). I wasn't sure I'd get focus but it worked a treat. My ASI120 suffers badly from Newtons rings and flats didn't work very well. Even with the ADC they're stlll there but very faint and they vanish during stacking.
  11. Nothing spectacular but the main purpose today (20 Nov) was to try and see if I could use my ADC for removing newton rings on my PST ASI120MM set up. Indeed it seems to work rather well! All the concern with setting it up meant that I neglected to get the tuning right, so I am slightly off band, but what the heck. :gaga:
  12. The C8 at f.15 using the ASI120MM and Baader 610 pass filter. Gassendi: Goldshmidt: Hainzel and Wilhelm: Herschel: Hippalus rille:
