great advises -- I figure those out the hard way.
Add other things:
- Remove Filter!
- Make sure shake reduction is off (on lower-end model, K5 apparently turn that off automatically for long exposure);
- WB should be 'sun';
- Pentax lens infinity also more like Canon in the video, it goes pass infinity.

Hope he mention how to post-process the photo.

How many shots should you have to have trails?

Mojoe, I believe a much longer exposure in bulb mode, maybe stopped down a bit & iso turned down slightly should provide for star trails.

Or if it is multiple exposures, maybe ten an hour all for an entire night to provide the necessary trails.

Just a guess though.

I saw this vid last night and very very helpful... Good find!

Do you think on the focal length he is talking about 35mm equivalent? or Crop Sensor focal length?

Ben Canales is a great photographer. You have to admire him when you think about the fact that he lives here in the gloomy northwest (and therefore has to gamble on whether it's going to be clear outside at night at all a lot), and is frequently standing around all night in the cold playing with composition.

My attempt at a Moon shot.. tried to follow what the video said and had to make some minor adjustments... for my particular lens (Tamron 10-24mm) I should have shot it at around f8 or so to have the schools in focus.. in the pic they look a bit blurry and bowed.. right ? or is that just my eyes from all the recent late nights!

thanks!

One article that I found on the subject states that for "crop" cameras its the rule of "400"
QuoteQuote:
For crop body cameras take 400 and divide it by the focal length of your lens.

And this makes sense since if you take 400/50mm (actual focal length) =8sec it's the same as 600/75mm (effective focal length due to crop factor) = 8sec (assuming a 1.5x crop body like we have in the Pentax DSLRs). Of course this also means you can ignore the 400 and just divide by the "effective focal length/crop factor if you like...

Glad the OP posted this since I am going out into what passes for the mountains around here next weekend and hope to get some astrophotos with the K-5 and DA*16-50...
