Metaguide collimation

[Chris-h]

I thought I would give this a go with my C9.25, and it seems to work well. However, I noticed that I'm only collimated in red (I used an IR pass filter when collimating). Green is off, but blue is really bad.

I used Capella, which was quite high at the time, so I don't think it's dispersion. Could it be the optics?

Thanks!

Turns out it was dispersion. I didn't think it would be that bad at that altitude, but it was.
