boxerman's recent activity

  • I'm not speaking from much experience, either, but here are some notes about things I've read: Stars should actually be easy to align, but algorithms meant for general landscapes might not be optimal.
  • Replied in Congrats!
    Oh, and I forgot to ask about starbursts. Since a small aperture is a non-starter, this must have been added in post, no? I think I've seen a Photoshop filter that does this.
  • Replied in Congrats!
    I think these are very nice, and I completely sympathize: We're at the limits of current m 4/3 sensors. I am not sure I'm up for middle of the night shooting. I was spoiled with my first astro ...
  • Very sensible. Try, and learn. Yes, true. But when it gets sub-pixel streaking, of course, there's nothing visible. I worked through this pretty thoroughly with somebody else on the forum a while ...
  • Yes, I don't and didn't dispute this. It's the capturing of a good light-painted image that I was talking about. Yes, but live composite starts fresh on each exposure. You have to accumulate a ...
  • We print large on occasion. On a 16 x 19, you have to get within a few inches to begin to detect pixels. We have a 40 inch print in our living room, and the pixels are simply not detectable. ...
  • Kibitzing. Hope you don't mind. Not speaking from experience, but I think I understand the "mechanics." I would think live TIME would be the best way to do this. Essentially, you just paint ...
  • So, then, the number of exposures was close to mine, about 120. The impression that my streaks are longer is probably due to the 20mm lens, rather than your 12. Well, once you've saturated the ...
  • Looks pretty good to me, with some tentative reservations. I haven't yet tried live composite, but I gather it does a sequence of exposures (what's on you exif), and combines on a "brightest ...
  • I bought one for $100 about 4 years ago. It died recently (refused to focus), and I just bought another at the same price. It's so cheap, and so worthwhile. Practically disposable, but nearly ...
  • Replied in Two "tricks"
    For those who own the E-M1 II, there is a setting to "pre-set" a particular focus point and recall it later. So, presumably you can focus during the day (any far-away subject) and then "recall" it ...
  • Replied in !!!
    These range from wonderful to absolutely unbelievable! Cannot figure out some of the techniques (ghostly after images). Anybody know where he's described his work? Yeah, over 40 expeditions most of ...
  • Excellent!  I find it uncanny how well my handheld shots come out. (I generally use OIS with my E-M1 II). I've almost stopped worrying about shutter speed. Looks like you could have dropped your ...
  • What scared me was the coma as astro photography is probably my use for this lens.
  • Looks very nice. BUT, it seems to have only one base plate option, with the connecting screw in the middle. The E-M1.2 has the connecting screw "socket" all the way to the front of the camera. I ...
  • Thanks. As soon as I have time to read it...
  • Very interesting and beautiful. I'm most curious about the particulars of the optical set-up. Wonder why he needs such a long lens. Why the big, curved mirror; couldn't he use a lens instead? I ...
  • Oops,  on searching a bit more, I think I answered my own question. You  CAN use bulb setting from the remote clicker: Bulb Protocol (Click on the next to last supplementary figure.)
  • This looks good, but I wonder if you can tell me one thing. I would not be happy if I could not use a "bulb" setting (keep the shutter down, without literally keeping the button pressed). It looks ...
  • Great work. Congratulations! How do you manage your focusing with busy backgrounds? I'm a BIF novice, but I find my E-M1 II can track well IF I catch the bird in the sky before it gets to the busy ...
