Guest )-( Posted November 30, 2015 Share #41 Posted November 30, 2015 Advertisement (gone after registration) ^ Good job it doesn't do 120 seconds in that case! Personally I don't mind the NR delay when doing this kind of shooting, it's slowed down work in any case. Stalk out the next shot, enjoy the view, boil the kettle, enjoy the waiting.. I agree that the 60 seconds limit can be annoying but it is still lots of time to smooth a sea, or convey movement in clouds etc, absolutely loads of time. If it didn't happen in a minute, will it be happening in 4? 240 seconds would of course be nicer to have, enough time to give more freedom of choice (always preferred) but 60 seconds is certainly something to work with. Personally I'm not an astro shooter, too fiddly by half! But I agree with the sentiment before that if you want static stars then you're looking at /500 rule anyway. 500/21(mm) = 23.8 seconds. 500/18 = 27.8 seconds. 500/15 = 33.3 seconds. Serious landscape work just isn't possible. Everyone has their own requirements, I think that's a barmy assertion personally(!), but we're all stuck with 60 seconds whatever they may be. Does a 'Q' provide long exposure satisfaction, or is that another 60 second situation? Link to post Share on other sites More sharing options...

Vern Dewit Posted November 30, 2015 Share #42 Posted November 30, 2015 What I find most annoying isn't the 60 second limit - it's the 8 second limit at high ISO's... To use my 21SEM for astrophotography wide open, I need around 20-25 seconds at ISO 3200 or even 6400 to get a nice Milky Way with no star trails. This renders the M240 unusable for this purpose for me. I use a Sony A7s or Fuji for astrophotography. Link to post Share on other sites More sharing options...
sdk Posted November 30, 2015 Share #43 Posted November 30, 2015 I think it would be best to shoot astrophotography on the Leica M Typ 240 at or close to base ISO 200, as this would allow the longest exposures record the most photons, assuming you actually want 60 seconds, though under the 500/FL rule for keeping stars from trailing you wouldn't want exposures that long. Higher ISOs are just amplifying the base ISO signal (and noise) anyway, and the shorter exposures the M cameras allow at higher ISO are recording fewer photons. With a 21mm lens try 24 sec at ISO 400, then push the DNGs in post-exposure to the desired brightness. They should be no noisier than if the camera actually allowed you to do a 24 sec exposure with a 21mm lens at ISO 3200. The noise in long ISO 3200 images might actually be a good deal worse than a pushed ISO 200 or 400 image, probably due to thermal noise. The big disadvantage the M's have in astrophotography is you can't do a 10-30 sec 3200 or 6400 ISO test shot for focus, like you can on a Nikon DSLR, but an 8 sec ISO 6400 shot should give you at least the brightest stars to check focus on the screen or EVF.But it seems like the best photographic tool for general-purpose, wide-field astrophotography would be the Nikon D810A, which has extended long-exposure capability beyond a regular D810, and extended red sensitivity for H-alpha emission nebulae. I doubt Leica would ever market an M camera to compete with that, though they probably could. It seems they would rather just design limited edition stuff like the Lenny Kravitz Edition M or the M60, which don't extend the shooting envelope of the regular production cameras in any way, but which do pull in money from collectors.

Peter Kilmister Posted November 30, 2015 Share #44 Posted November 30, 2015 In huge swathes of Europe, especially the industrial or commercial centres. it would be almost impossible to see a star ... except for the sun during the day ... and provided it was a dry day. This is one of the reasons there is a conference in Paris at present. All the electric lights create so much light pollution and they don't do it without consuming huge amounts of energy. It is a fair question from someone in Alberta, Canada to ask for longer exposure times. I wish it was a fair question here. Link to post Share on other sites More sharing options...

I regularly see a sky that you'd be amazed that is less than an hour from a city of over 1 million people. We're pretty privileged that way in Canada. I do think that ISO 400 for 24 seconds would produce a pretty amazing shot in some of the locations I've been. I'll have to give that a try. Link to post Share on other sites More sharing options...
Gary Clennan Posted November 30, 2015 Share #46 Posted November 30, 2015 Hi Vern. I have tried many times to get some good astro exposures with the M240 but have not had any luck. I've had some ok images but nothing approaching the level of quality from a good mirrorless or DSLR. I've tried pushing in post but things turn rather ugly quickly in the shadow areas. The only answer (as I see it) is to use a tracking mount for around $500. That may not even be enough though.... Link to post Share on other sites More sharing options...
Peter Kilmister Posted November 30, 2015 Share #47 Posted November 30, 2015 Advertisement (gone after registration) You are very lucky to live where there are dark skies. Even though we have no street lamps in our Parish there are people who insist on halogen 1000 Watt security lights. Grrr! Link to post Share on other sites More sharing options...

It's going to be very hard to beat an A7s or Fuji sensor which are pretty much noise-free at ISO 6400 and even higher. I think it's more about using what you have with you at the time. If I'm ever out camping under a nice dark Alberta sky, I'll give it a shot and report back. Interestingly enough, I do own an iOptron Sky tracker but I never bother lugging it around.

I do a lot of long exposures, I agree that 60 sec. is generally enough for smoothing the water but not for the clouds, that often require several minutes Link to post Share on other sites More sharing options...
jaques Posted December 2, 2015 Share #51 Posted December 2, 2015 "Serious landscape work just isn't possible" seriously? do all 'serious' landscape photographers generally expose for more than 60 seconds, these days? Just like in the 1890's? Link to post Share on other sites More sharing options...

jmahto Posted December 15, 2015 Share #55 Posted December 15, 2015 This Sunday there was Geminid meteor shower and I decided to try out my M240 for interval shooting. I did the following: - ISO 1600 - Open my 28 cron fully f/2 with infinity focus - Shutter in continuous mode - Leave the camera face up on the table in my backyard - Trip the shutter with a cable release and lock it so that shutter remains pressed I let it take 8 sec interval shots (with 8 sec dark frames in between) till battery ran out. I used two batteries and got it to run all night for 7 hours. I was pleased with the results. I got 9 good meteor streaks. Note that I am in suburb with enough light pollution. Compared to my other camera (Sony nex6 with 15 CV with no dark frame in between shots), I got better captures with M. Yes, I would have liked no dark frame but I am not complaining. I should also add that I liked 28 cron ASPH perf wide open. The stars in the corners were not fuzzy but had little bit of coma which is visible only when you pixel peep. The first shot is a slight crop of a very bright meteor with Castor and Pollux of Gemini in the same frame. Welcome, dear visitor!

Tmuussoni Posted December 19, 2015 Share #57 Posted December 19, 2015 For those of us who want (and need) more than 60 second exposures we just have to be vocal about it. That is the only way for Leica to notice us. Let's hope the improvements of SL with a real bulb mode will be carried out in next generation M body (please, please, please!)

Let's hope the improvements of SL with a real bulb mode will be carried out in next generation M body (please, please, please!) Bulb mode but no external shutter release connection as far as I'm aware so it would need to be fired through an App on a smart phone. The "Remote Control" allows connection of an accessory (can't find anything in the SL's baffling manual about what type of remote shutter release to directly connect) although it's a bit smaller than a type A USB or USB 3.0 and it doesn't appear to be a standard connection port type that i'm familiar with.
