  1. Dear mates, my recent attempt with Samyang 135mm on Dolphin nebula with Optolong L- extreme filter and a Sony A7 camera. CS Rush Optolo-eXtreme
  2. Well, dithering + Lp filter is more essential than long cooling intervals in my experience. Keep ISO low, for instance 400, exposure time 120 seconds and shoot one or many nights the same object. Try not to use Live view screen. Its quiet true what mate Alacant says. On the other hand if u r really concerned about cooling the camera, use a table FAN and blow on the Camera at a slow rotation naturally. Cheers Rush
  3. This is a new attempt with Samy 135mm fully open and Canon 5D . Processed without cali frames, laziness amazes me. CS Rush
  4. This image of Lagoon & Co is with Sammy 85mm and Sony A7. Lens is quiet heavy for an 85 mm, works fine. Cs Rush
  5. Ah, interesting. my brain pixels too binned now.😜 manually. Humming teach ur children well.
  6. Hi Adam, had this Camera for 6 months, tried the unity gain ( corresponding 120 s) in SGP. Result was extrem Col.noise and stars were kind of overexposed , RGB histogram by far misaligned . In the course of time, turned down the gain to 70 and from 300s to 180s and the C.noise dramaticaly went down . This is purely my expeirence. I cant try this again as I sold off this cam. Was trying to combine the lum from CCD with CMOS OSC. In the end I gave up, lol. Adam , did you use this camera or did u check personaly how the gain values respond ? Curious 2 know, probably my handling was wrong. This was my low gain attempt HLRGB. cheers Rush
  7. Hi, Reduce the gain, start from 60 or 70 instead of 120. Off set leave at default. Frames @180s or below. Use an IR cut filter. Cleaned up ur image without cali frames, Im allergic to cali frames 😩. Hope this helps.
  8. This is an HALRGB version Orion taken with Sammy 135mm and SBIG ST-8300M. Was a windy night , focus shiffting at regular intervals. Star spikes, not thin edged due to vibration i guess. CS Rush
  9. This is what remains after cleaning up. RGB channels R G B CS
  10. Can u upload a stacked image right out of APP or DSS. Not touchiing the saturation silder ? CS
  11. Added 3 hrs of Ha and O3 to the Sony DSLR image fully wide open at F2. My eyes cannot see the occilation nor the incoherence of the light signal. Cant say overall SNR s improved or aggravated the phase distortion by the filters . The colours look different and some of those dust lanes, star colours vanished and Nebula itself became more dense. Baader 7 nm and Baader F/2 High speed O3 filter were used. CS Rush DSLR image N band added.
  12. Southern beauties 🤩 with Sony A7 and Canon 600D Antares region LMC Cats paw and Lobster Running chicken CS Rush
  13. Hi, Roberto on Astrobin uses Fs 60 CB . You can take a look at his collection of Images with FS60. https://www.astrobin.com/360918/?nc=user well, I have used a couple of them too, Its quiet sharp and focus remains kind of steady even at temp fluctuations. Somtime back i wanted to dispose one of mine. Hope this is of help, CS Rush
  14. Adding one more Samyang image. ( 3 hrs with a Sony A7) CS Rush
