  1. Amazing difference between the two captures, such a dynamic planet to observe/image.
  2. It seems very difficult to get much info on the QE curve of the cameras below 400nm.
  3. looking forward to seeing that crescent get thinner and larger over the coming weeks.
  4. I certainly think the phase is probably a bit small now. I prefer to see at least 50%, oddly Venus does seem to be smaller than the actual "advertised" size.
  5. That is an interesting graph, assuming the figures at the bottom are the wavelength. What do the figures at the side represent?
  6. Fantastic looking images, love the color Lunar images.
  7. Yes definitely got some, i will probably have another play with the data over the summer.
  8. Spent quite a while trying to find the white light 3 Active regions on the Sun on Sunday, only to realize somehow i was viewing an old web-page from the day before. The A/R's had dissipated overnight 🙂 In the end the cloud ended the session anyway. These image were from the 26th, only just got around to processing them. The disc is a 12 pane mosaic. All H/A images are with my Lunt 50mm/Dmk21au618, the white light was with my Evostar and Lunt wedge.
  9. Beautiful prom captures.
  10. What a great start with the camera, lovely faint wispy details there!
  11. Very nicely captured.
  12. Nothing to be ashamed of there, some nice details visible in those images.
  13. Very nice, its a beautiful sight through the scope at the moment.
  14. Very nice looking image, going to try and image Venus for as long as possible. It would be nice to get an image thinner than the other years 3% phase.
  15. The amount of time i have spent processing these images has been probably too long. Trying to get somewhere near the magnificent images by @CraigT82 @lukebl and co has been a mission 🙂 Not sure that my SCT scope will allow enough signal through compared to large newts due to the coatings. (maybe aperture fever is going strike again) Been great fun capturing, processing and chatting to others who have imaging this wonderful target in the UV wavelength! not managed a presentable "false colour" image yet though. The data is saved so i will still have that to play with. All images captured with C9.25, Asi 290mm, X1.8 Barlow.
  16. Its going to get harder and harder over the next couple of weeks.
  17. Excellent set of images there, great reward for your efforts.
  18. An Interesting view of Pythagoras last night, due to libration. It looked like the edge of the crater had become detached due to the rim being illuminated and the crater in shadow. Not the best seeing, but this image gives a fair representation of the view i saw. I don't recall seeing this before, so it was a very interesting view for me. The usual set up of C9.25, asi290mm and 642 Proplanet filter
  19. Cracking looking Moon, the seeing was a little wobbly by the time i viewed it last night.
  20. I tend to use Calsky to find out what position Venus is in relation to usually the Sun or the Moon. At the moment its 35 degrees from the Sun and approx 35 degrees high. I then use my outstretched arm/fist (fist is 10 degrees wide) to measure where the position should be. I then use the finder scope to locate Venus, can be a little tricky. Obviously keep a very close eye where the Sun is when using any astronomical equipment. I nearly always position my self in the shade of the shed, so i can not accidentally point the scope at the Sun. A few weeks Venus and the Sun were 50+ degrees apart, they are closing very very quickly now!
  21. I don't know if you image at all, but this was all i managed the other week. Barely make out the equatorial belts. Just a question as well, is you scope left outside or do leave it out for a while to allow it to cool to outside temperature before using?
