  1. It's Langrenus. You can download the Virtual Moon Atlas here It's a brilliant tool to use for identification or planning.
  2. Thank you for the replies. I have used a colour sampled 'control point' but my black point is normally set at about 15-20, so I'll try with some higher values to see if it makes a difference. Was concerned I'd lose some dynamic range but is probably worth it to gain a smoother result.
  3. One big problem I have when processing my deep sky images is trying to make the (almost) black background show up consistently between different monitors. I have two at home, one old and one nice new one. I do the main processing on the new monitor and can make the background look nice and clean and galaxies have lovely, soft edges. If I look at the same image on the other monitor the noise shows up much more clearly or the soft edges on the galaxies suddenly are harsh and solid. If I try at a monitor at work I get something inbetween but it can still look much worse than the original. I'm guessing this is because different monitors have different responses to dark greys but I've noticed that many other people's images seem to show much more consistently between all my different monitors. It makes me paranoid about uploading images for people to look at as I worry that it will look completely different on everyone elses screen! Does anyone have any suggestions about how to get round this issue?
  4. If you don't win Astronomy Photographer of the Year for that then there is no justice in the world! Astonishing.
  5. Some fairly steady skies and favourable libration meant that I was able to have a go at imaging the moon's north polar region last night. In fact the 5x barlow even came out of it's box for the first time in a while! Here is a 6 pane montage of the area. Lunar North Pole Region by kyokugaisha1, on Flickr I then used Photoshop to stretch and warp the image to help see exactly what craters, etc. were in the image and annotated it via the Virtual Moon Atlas. Lunar North Pole Region Stretched & Annotated by kyokugaisha1, on Flickr Really pleased to actually get the pole itself imaged.
  6. This is a crop of a much larger montage that also contains NGC 5053 (which I'm still working on). I'm trying to improve my processing to emphasise star colours and give them a bit of a 'shine' that I see in other images. I think I've found a little workaround in PS which I quite like. Thanks for looking and please do let me know your comments regarding the processing as it's hard to keep objective when I'm staring at it for hours on end!
  7. Oops. Don't know what happened with that last one. Here it is again. M95 & M96 by kyokugaisha1, on Flickr
  8. I've started on the deep sky imaging again now Jupiter is getting smaller and before Mars/Saturn become an obsession. Here are a few of the images from a variety of nights. Unintentionally I picked 3 views of widely varying size which meant processing was interesting to say the least. Any comments or suggestions are very welcome as I have just bought a new monitor which really shows noise up in the dark areas of the image and I'm still trying to get used to it. First up is M1 - Crab Nebula (18 x 120s) M1 - The Crab Nebula by kyokugaisha1, on Flickr NGC 2392 - Eskimo Nebula (8 x 30s) Eskimo Nebula by kyokugaisha1, on Flickr M95 & M96 (24 x 120s) M95 & M96 by kyokugaisha1, on Flickr
  9. Ah, article says approx. a 40m crater. Bit too small for amateur scopes then.
  10. I was also very surprised by how dark it looked. I took the image below but the seeing wasn't really good enough to show it as anything other than a black circle - just how it looked to the eye. However WinJupos shows the scene very clearly.
  11. I reckon you were looking at Venus which rises in the south east at dawn. It's about magnitude -4.6 at the moment which would make it the brightest object up there apart from the sun and the moon.
  12. Thank you for all the comments. richmk3 - Yup, it was taken with the 200P. I have to say the two main factors are the 3x barlow and the very steady atmosphere. Most of my Jupiter images don't come close to this!
  13. Another few hours with perfect seeing, this time coinciding with a GRS transit and Ganymede nearby. My new Tele Vue 3x barlow has, I think, got my set up to the sweet spot between too much focal length and too little. I used 11 avis stacked and wavelets in Registax. Then derotated Jupiter in WinJupos. Have to admit when I saw there was something unusual about Ganymede in the final image I had to have a bit of a fiddle. I'm pretty sure the markings are actually on the disk itself and not just noise. They are visible on the raw stacked files and I tried a different stacking technique (AS!2) which showed the same sort of albedo variation. So I'm 95% sure I photographed the surface of a moon 670,000,000 km away... from my back garden! Sometimes this hobby does make you sit back and think. Jupiter, Io & Ganymede 2014-02-15-2041 by kyokugaisha1, on Flickr Thanks for looking.
  14. Got a shot of that one the other day. http://stargazerslounge.com/topic/206267-sn-in-ursa-major-no-not-that-one-the-other-one/
