Just got my 1600MM and its a beautiful camera. Already captured NGC 6888 in a very light polluted area, with an Ha filter. Couldn't believe it Focus problem though.
Oh well practice does it.
This camera makes it all fun.
The "suggestion" is regarding the two short USB cords meant to connect the guider camera and EFW. They are really short! I couldn't use the guide camera cable because it was 4-6" too short. Had to use a cable from elsewhere. Please make these a bit longer.
