  1. With regard to capabilities and features of the CGX, I have been wondering about using a QHY PoleMaster camera with my CGX. In the CGX thread on CloudyNights, this conversation took place about 10 days ago: FROM DERIK FROM CELESTRON: "Re: handle on the front of the [CGX] Dec axis. Yes, you can remove that. 4 screws. But the PoleMaster does not need to be perfectly aligned columnated with the RA axis to work properly. So you can mount it to the handle or you can put it on the (optional) polar finder bracket. Re: Polar alignment and astrophotography. What app

Re: Polar alignment and astrophotography. What applies to all equatorial mounts, not just CGX. I am not astrophotographer, but ASPA will usually converge to within 10 arcminutes of the
  3. Does anyone have information or a sense of whether QHY will or can develop a PoleMaster adapter that works with the Celestron CGX mount?
  4. Thanks for your thoughts and ideas. especially thanks to Olly (ollypenrice) re: using planetarium software to figure out camera and telescope combinations and FOV. I have used Stellarium as suggested and come away believing that I am on the right track with my spreadsheet calculations for FOV. With Stellarium there is good correlation with predicted FOV from my spreadsheet. From an FOV perspective, for M42 the camera suggested by Olly (ZWO ASI 1600M) appears to be optimal, although, the EOS 80D is not far behind. With the QSI 6120, the object may be just a bit large for the FOV availa
  5. Gerry, Great Images!!! You seem to have this down cold. I am for sure going to have to keep in touch with you. I have no confidence that my initial efforts will be anywhere near your results. Great going.
  6. Gerry, I can only load one (Triangulum) of your images, but it looks great!! The stars are round and I can't see much that would disturb me. Of course I'm not where you are in this learning curve. Another few months and maybe I'll be where you are today, and ecstatic. Great going!! BTW, is it only I who can't get your other photo to load from AstroBin? Do I have to be a member or be registered with AstroBin. Triangulum has loaded multiple times but not your second image.
  7. I am new to the astrophotography (AP) part of star-gazing. I am trying to get into it with a relatively big leap in a few short months. I have a Canon EOS 80D that is modified for AP. I am embarking on my AP career by getting into simply aimed, non-tracked, non guided AP with the EOS, a tripod, and BackYardEOS (BYE). Just trying to get used to the concepts of prolonged (1 minute to 20 or 30 minutes), multiple exposures with "Lights, Darks, Flats, Biases, Calibration, Aligning, Stacking, Post-processing," and whatever other term I may have left out. I'm presuming that I can play around
  8. Neil, Thanks for your thoughtful response. It's taken me a while to get back to you because I've been busy learning (or at least reading) a lot of stuff and working with Larry at Oceanside Photo and Telescope (OPT) to get my Astrograph. I've also been in touch with "HiloDon" in Stargazers Lounge who appears to be a principal contributor to Electronic Assisted Astronomy (EAA) or Video astronomy as you have phrased it. Between Larry and Don and you I have stumbled to the capabilities of the Starlight Express Ultrastar and the Atik Infinity. I am probably leaning to the SX Ultrastar. Bu
  9. I just pre-ordered a Celestron 11" CGX Rowe-Ackermann Schmidt Astrograph (RASA). It's "pre-ordered" so I can still cancel it depending on any insights anyone here can provide. I have been an off and on star gazer since 1978 with a Celestron 8" SCT. During that time I made some feeble attempts at piggy-back lunar photography. As has been said by others elsewhere, astrophotography 40 years ago was something of a "black art" with special requirements for special film and "cold" cameras. I didn't have time during medical training to put my feet in that water. Now retired I would like
  10. I have been an off and on star gazer since 1978 with a Celestron 8" SCT. During that time I made some feeble attempts at piggy-back lunar photography. As has been said by others, astrophotography 35 years ago was something of a "black art" with special requirements for film and "cold" cameras. I didn't have time during medical training to put my feet in that water. Now retired I would like to try my hand at astrophotography. I have pre-ordered a Celestron CGX RASA and some associated equipment. But I have a question that, if the answer to my question is wrong, may cause me to change
