Neximage reducer

[bigal1]

Hi all was wondering if the neximage focal reducer would work on my tocam pro2 and if not which would be the cheapest option for reducing the focal length , thanks .

Use filter threaded focal reducer - many shops have them, FLO has this one, and modernastronomy has 0,5x reducer that halves focal length at 40mm distance from the camera CCD - if the distance will be bigger - more reduction, smaller distance - less reduction (calculator).

For a Maksutov you can use the stronger 0.5 reducer. If you plan to use reducer more ofthen with eyepieces or other cameras you an also look at SCT reducers that can be attached to Maks via special connection ring (both shops have them). Those reducers are bigger, and they also work as flatteners and can be further from the CCD/eyepiece (10-6 cm).

Antares Antares 1.25" focal reducer 0.5x

screws onto the front of the adapter

Cheers folks will pick 1 up soon as , need to widen my view a bit for some moon shots .

[red dwalf]

they work great on moon pics, thats the reason why i bought one in the first place, makes hell of a differance when using a webcam or simular camera.

All filter threaded reducers are nearly the same. I have one and it's fun to make f/2,75 from f/5 newtonian But it also makes the coma visible in the DMK 1/4" CCD.
