  1. @Cornelius Varley Oh, OK. I couldn't see that. Then, it must be so.
  2. Not at 7 p.m. in the UK. I have 7:31 for my location in the middle of the UK, today. I think we need the OP's location, first.
  3. @Xilman Ahh, good to see correct use of SI units for the critical dimensions of your telescopes. Keep up the good work.
  4. I've not heard that term in years! I really must read the books, again.
  5. My rings are threaded on both sides, so I plan to add a second dovetail, then clamp things to that with a Vixen clamp. Alternatively, get a piece of aluminium bar and drill to suit.
  6. @PatrickO In addition to @vlaiv's comment on tracking, I would add that it can be advantageous to not track or to allow the Moon to drift through the FOV. If you have any dirt or defects on the sensor, these will automatically and magically disappear when you stack your images, since the stacking software will not see them as features to be stacked. I have a dark mark on the sensor of my camera and it never causes a problem if I am stacking.
  7. Part of the southern hemisphere of the Moon near the terminator at 81% waxing phase. This is a stack of 18 images at 2.4 m focal length with the Nikon D800. Processing in AS!3 and GIMP.
  8. Nice captures. I was having similar problems tonight with the clouds and lost the northern regions completely, but did OK in the south.
  9. Daft question: but, have you checked that the locking screw on the sie of the focuser is not too tight?
  10. Reprocessed version of Earthshine. Gaussian blur applied to mask the noise.
  11. @Mr Spock Thanks! I can't wait to get some images with the Herschel wedge. I've had a look visually, but cannot get focus with a DSLR, so I need to set up the ASI 178MM.
  12. Wow! I managed to see the Sun today and for long enough to grab sufficient images to make a half-decent stack. Skywatcher 200P Thousand Oaks solar filter Nikon D800 f/5.9, 1/500s, ISO-100 Processed in AS!3 and GIMP
  13. Slightly noisy image of the night side of the Moon bathed in earthshine. No stacking done, as I wanted the clouds to feature. Skywatcher 200P Nikon D800 f/5.9, ½s, ISO-1600 Processed in GIMP
  14. @Richard N The name of this forum has always irked me, so I agree with you. Whenever engaging with the public, I never use such terms and stick to astronomy, astronomer, etc. I have been referred to as an astrologer on numerous occasions and even asked if I would cast someone's horoscope. I think I would have based it around the seventh planet, if I'd been bothered to humour them.
