  1. 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

  5. Hi Sean, 1. it weighs 3.3 kilos. 2. No, Im in europe. With fright and Paypal fee it comes around 240 euros. "Ultima Thule" puts you in the Kuiper Belt. Very true But NASA renamed it ARROKOTH . No more UT. Arrokoth was named for a word "sky", from the Powhatan Language, pronunciation and meaning of the word, however, are not entirely certain, as the language became extinct in the late 18th century and little was recorded of it. U might it like it. take a look , https://en.wikipedia.org/wiki/486958_Arrokoth. Cheers Rush

  9. 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
  10. 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.
  11. 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
