I've got an ASI183MC arriving this weekend, and an AT60ED on order. I'll be pairing these with a Star Adventurer 2i to begin with, which has an autoguider port. Although it only guides in RA I'd like to make use of it in the near future.
While I'm looking into guiding solutions for this setup I also want something that will compliment my larger 8" f/8 1600mm FL reflector down the line.
This has brought me to two options:
- Order a small mini guidescope and mini guide cam to use with the AT60ED on the Star Adventurer
- When using the 1600FL newtonian attach the AT60ED with mini guide cam and use that for guiding
- Go with an OAG and mini guide cam and use it for both scenarios
I like the OAG option (it's the simplest after all) but I don't know anything about OAGs. What are the pros and cons vs a dedicated guidescope? I like that it operates at the system FL, so will give me the accuracy I require when shooting at 1600mm or longer. What about obstruction of the sensor frame? I assume the small sensor on the 183 won't have a problem with it, but what about a full frame sensor down the line? Other considerations?
