Quote:Guided or unguided? I would bet that all of the star selecting and calibration that guiding would need would push you not to use it. In that case, can you get 1m subs without guiding? If so, give it a shot.

Quote:>>>>>I need to have the ability to see every image as soon as it is finished to confirm focus.Dude, reconsider. This is a deal breaker. You are not just trying to run a marathon, you are running it in steel-toed boots with a Hazmat suit on. If your equipment is not working right, it is a great challenge.

Quote:I still might go to Staunton River. I am just not sure if I can get away for several days. I also don’t want put the red filters on everything. I don’t use eyepieces at all so dark adaption is not an issue for me. However, I don’t want to make everyone mad at the star party either.If I can run everything from within the tent and mask the light pollution that I might create then I will probably go up there. If not I will just go to s semi dark site where I won’t be bothering anyone else.

Quote:>>>>>I tried it the other night with one of my older cameras and I was able to get at least 4 images of 12 objects per hour.You sound like you are ready.....Good Luck. Alex
Quote:Groups? Lots of Messier objects are together, 65-66, 31-32-110, 42-43, 81-82, 97-108, etc. Have you though of just making sure that you can get them both in the frame easily, and taking 1 extra sub, and thus saving some time?
Quote:1. Hypothetically speaking if you were to cover 110 objects in 8 hours of darkness (one night), you’ll have ~480 minutes; 480/110=4.36. Your 5 min/object estimate is close given you might not get all if few set with the sun...
Quote:3. You’ll probably need to squeeze in few darks; may be ~10x1min at ISO1600. You could do them at the end of the session if temp difference will not be large.
Quote:5. Do your homework ahead of time to arrange objects in such a way so there is least slewing needed from one to the next; again starting from west to east.
Quote:6. Also arrange objects in such a way so you do meridian flip only once (western to eastern hemisphere).
Quote:7. Your mount’s pointing would have to be nearly perfect; if you are going to a star party then rehearse how quickly you can get your mount setup/pointed early in the evening.
Quote:11. “Wheels up”; try not using a laptop; save images locally on the bigger/faster memory chip; only exception would be the external power supply to the camera, if applicable.
Quote:14. Build focus check points into the plan; lesser the better.
