  • I noticed this issue when I wast trying to make my astrotracer function work last winter, but had other things to think about. But what is the cause of the faint 'halo' around brighter stars? In ...
  • I don 't disagree. As I recall, astrotracer said I could do something like a 180 second exposure. But there is too much light pollution in my backyard for that length of time. Maybe I'll contact ...
  • Looking at my saved images,  two days after I did a successful calibration I took more images and they showed trails. Also,  I noticed a big difference between just the simple calibration and both ...
  • Created photo thread This morning's Moon
    I just can't help myself - it's too easy to just step outside and snap a few images. These were taken before sunrise this morning, but the sky was already light. I've included the jpeg exported ...
  • Yes, I tried that. I have photos showing no calibration, simple calibration only, and both calibrations. With 20 sec exposures at 70 mm the differences are obvious. i spent a lot of time and effort ...
  • When I first got the GPS add-on to my K-70, and after talking to Customer Support I was able to achieve regular calibration and then the precise calibration a few times. I usually had repeat each ...
  • Hi John- you've gotten a lot of fine images (including this one) from this pond and the surrounding woods. But what's with the lower left? Is the water moving? David
  • Thanks Tom. this is the southeast corner of my yard. in the winter, sunbeams light the roses but nothing else. I don't know why I didn't notice that before. David
  • Yes, that dragonfly is indeed, 'nice large'. David
  • Even though it was early morning, these guys were swaying in a breeze and it took several tries to capture them without motion blur. This shady fence is my new favorite background. David
  • Well, ok. Affordable, high quality lenses. I'm disappointed that Sigma is not offering the Art lenses in Pentax mount. 18-35, 30, and 35 mm are the only ones. Maybe you can recommend some Pentax ...
  • Thumb image: View at 400% - PS off on left, DCU PS center, and RT PS right Next view. There was some wind, and a few leaves were moving around. Left is PS off, center is PS through DCU and showing ...
  • I already responded here . Here's another comparison of RawTherapee (on left) with DCU (300%) Not much difference, really. Thumbnail version of the image here: If you don't think there is much ...
  • I, too, have had problems with AF. But only for wide FL. Shooting the Moon should be pretty easy for AF when it's on the Moon's limb. Great contrast, black on white. If you are having AF problems ...
  • Replied in Into the Void
    Thank you for your kind words, John. When I 'discovered' this scene, I thought it was magical, and spent some time with it. I must have posted this on my pBase site - one does get responses there ...
  • I've tried both DCU 5.6 (powered by SilkyPix) and RawTherapee 5.2. DCU has no user-settable parameters, just Motion Correction 'on' or 'off'. RT is very rich with features and I may not be getting ...
  • Mike- This is the SD1M with the 150-600 mm (C) lens. I used the wavelet processing in RegiStax 6, and it stripped out the exif info. I export the image from SPP as a double-sized 16-bit tiff, ...
  • Bob- Why are you using f/11? I'm using f/6.3 - lots more light. Also, how about trying your SD1M, so we can see how much of the noise is from your technique, and how much is from the camera? David
  • I didn't consider color, since I didn't know what the actual colors were. I considered sharpness and noise. The TZ110 and the Sony seemed similar in sharpness. In terms of noise, the tz110 was ...
  • Its only a BIG problem if you're a pixel peeper. :-) this is the Sigma 17-70 mm (C) lens.
