For the interval composites I use "Startrails" application,http://www.startrails.de/html/software.html You will find several more examples...

Today I finished my gallery of photos from a trip to southern Africa (South Africa, Namibia and Botswana), which I took last July, together with my sister and nephew. The gallery contains a...

Tom, besides the Russian M42 lenses, it should be also mentioned that there was another huge group of M42 lenses, some of them of excellent quality, still at reasonable price - lenses made in East...

Comet C/2011 L4 PanSTARRS, captured with my GXR A16 last Saturday evening south of Prague. Taken as part of a time-lapse series (already on my time-lapse website). Exposure 2 sec, ISO1250, F/4.8,...

Milky Way, see the timelapse movies - its clear from them:http://www.setvak.cz/timelapse/2012a_SA-Namibia.html Martin

Thanks, Gerd. Yes, the night sky was incredible there. What I also liked (beside the darkness and clarity of the air there) was the absence of air traffic - I don't recall seeing a single plane...

Hi Gerd,thanks for posting this. As a matter of coincidence, last weekend I was also playing a bit with the dynamic range, but must have been doing something wrong. Definitely your samples motivate...

Hi all,here are two "startrails" images (created by the Startrails Application), assembled from my timelapse series of the southern starry sky, captured with my GXR A16. The first image below is...

Well, obviously it was my stupidity that I did not check the diameters before buying the B+W protective filter. The image below nicely shows that the outer diameter of the filter is significantly...

Thanks Hans for your info. Please, what is the external diameter and height of your filter? My B+W has an external diameter 58.0 mm and height 3.4 mm (when mounted). I guess that it is the diameter...

About a month ago I raised this question at the Ricoh Forum: http://ricohforum.com/phpbb/viewtopic.php?f=60&t=9152 (copied below), with no answer. Perhaps anyone here, at this forum, has any...

I would go right away for it. For sky photography and timelapsing (astrophotography, atmospheric phenomena, aurora, clouds) the 17mm EFOV would be ideal module. Provided that it is sharp enough and...

Just not to duplicate posts, here is a link to four of my July shots from our southern Africa trip, "GXR A16 - Night Sky from Namibia and Botswana", which I posted there...

Thanks for all the comments here, at the end I decided for the JJC one ( http://www.jjc.cc/products_info.asp?id=886&cid=0&pid=0&s_series=all ), resembles very much the Acmaxx one recommended by...

I know there are already several threads here addressing this issue, for now I just want to ask if anyone has his/her personal experience with one of these two LCD protectors: Vanguard Protector 45...

This weekend I continued experimenting with the GXR A16 24-85mm unit; the image below is at ISO1600, exposure 8 seconds (without DFS), 24mm at fully open, and is part of a 60-minute timelapse...

Very nice and interesting photos! As regards the dark frame subtraction (DFS), GXR with the A16 zoom unit applies it from 10-seconds exposure on; up to 8 seconds DFS is not applied, regardless of...

Hi Michael,I was considering Panasonic G3 or GX1 myself, but in the end decided for GXR with A16 ... namely for its timelapse capabilities and possibility to set the focus to infinity (almost a...

For about 10 days I own GXR with A16 24-85mm unit, and besides many test shots I also tried its timelapse (interval) capabilities, both daytime and nighttime.Here is one of the images from a...
