Now should I add the G1X?I'm hoping to create a lightweight backpackable astro kit...the G1x + Ioptron Skytracker + Berlebach Mini.CHDK removes the need for the external intervalometer and I'm thinking once I can really dive into the CHDK threads I'll find a script what honors bulb ramping (or something close).
All that is left is to figure out how you did the external battery (or did you yet).
I see the ongoing quest to defeat the manual focus lost to autofocus once the screen is turned off BUT with the lightweight nature of lithium batteries why not just give in and carry the extra larger external battery and be done with it?p.s. the plastic bag trick for weather proofing was brilliant!
.. and the fear of amassing so many shutter clicks BUT you don't seem worried with multiple thousands of clicks on your G1X.
-Did you ever get the histogram/metering features into trunk? If not, where can I get a build for SX50? Also your timelapse script.
-I'm interested in exposing the moon properly as it moves across the entire frame, so what I was orginally searching for is a way to get a histogram for the entire frame (based on the RAW buffer), and in fact I have no stuck pixels that I can detect so I want *every* pixel to be less than 3968 (the measured saturation on my camera)
-Your problems with whitebalance are easy to solve in an Avisynth script, I could make that for you. Interpolation between white balances between start and end frames can be done with the animate command.-You may also be interested in what I do further with my moon shots, it's called stacking, a common technique in astrophotography. I find the simplest program is Astrostakkert!. Basically drag the 25 shots or so of the moon moving across frame, and it lines them up, including pixel-by-pixel as it waves due to atmospheric disturbence. The stacking accomplishes sharpening and noise reduction. The result is quite amazing!-There is also a planetcrop.avs script in Avisynth that centers each moon image, for some other stacking programs that have trouble locating the moon anywhere across the frame.
-Finally I'm interested in the full frame histogram to do extreme HDR, to make sure there's a shot with no blown highlights and some lower limit for the shadows. At night I've had to exposure up to 8 minutes. (and I have no hot pixels).-I'd also like a real normal daytime exposure mode that makes sure no highlights are missing. As long as the sky is not in the shot In fact in some cases I really hate the sky looking all white instead of blue.
