OAG8300 Question

[Hans Tucker (Hans)]

Anyone know whether the SBIG OAG-8300 will allow the fitment of any guide camera or is it only specific to the SBIG ST-i.

[naskies (Dave)]

Any guide camera that is in a 1.25" eyepiece style format will work fine, e.g. a Lodestar will reach focus in the OAG-8300.

However, a QHY5 can't reach focus because there's not enough inward travel with the way the OAG-8300 is designed.

The OAG-8300 also has a built-in 0.7x reducer, which works great on the ST-i but it can't illuminate the full chip on the Lodestar - only maybe 80%?

Thanks Dave, exactly what I wanted to know.
