  1. Hello Leica-land, Been doing some lurking in the forums for some time, but can't find a definitive list of lenses suitable for astrophotography. Main things I'm looking at are fast aperture, low coma, flat field performance. Fast aperture may be not a total dealbreaker with the high iso abilities these days (using an M10-R BP, currently) especially if a tracking mount is used. That said, I haven't seen too many folks doing astro with Leica cameras/glass, though I know it's possible given my first Milky Way run of the season this year. See below for my shot of the Milky Way competing against the light pollution of NYC taken this weekend. Currently I've only tested my existing lenses (Zeiss 21 2.8 and 50 Lux 1.4. ASPH) and both seem to have horrible coma even stopped down. I mostly used the Zeiss and even at f4 I found spots of coma, though interestingly not uniform (maybe there's some field curvature going on here where one corner is better than another?) I've read about Leica's own fast wides, but most seem out of my price range at the moment. I'm definitely getting a Zeiss 35mm 1.4 which may fit the bill for this use as it's pretty darn near optically perfect, but are there any wider lenses the community could recommend? or am I doomed to lust/save for the 21Lux or 28 Lux/cron?
  2. Milky Way over a bridge near my hometown. (Leica X2 at f/2.8, ISO 1600, 15 seconds).
  3. Hi all, A few months ago, I started a thread inquiring how well suited the X2 was for taking star-scape photographs. I'd like to contribute to the answer to my own question with a few examples of images I made last weekend in Colorado at the Rocky Mountain Star Stare (a star party held at about 7600 ft. elevation). Under nice dark skies, the little X2 can really perform. The first two photographs were made at f2.8 and 15 seconds at 3200 ISO. At 15 sec. stars are beginning to trail due to the rotation of the earth. The third photo (same subject as the first) was made at 8 sec. Trailing is not an issue at this shutter speed. There is a higher noise to image ratio at 8 sec., but it is easily controllable, and the final result is no less realistic. (For those who don't mind stars that look like short sausages, 30 sec. can be pretty amazing.) I desaturated the second and third image somewhat for better verisimilitude—although, really, the eye cannot see even that much color in the Milky Way, but a little color looks nice, I think. All photos were processed (quickly and dirtily) in Lightroom and exported for email. I hope they work well with your monitors. All in all, I'm very happy with the performance of the little Leica for making star-scape images. Brent
