Re: DSLR Powermate combination on M110
- Every barlow lens extends focus position. Powermates are special barlows who extends it only a small part, but anyway you can't reach the focus in the same position as before.
AFAIK, you put the barlow before the diagonal you should achieve more x power. After the diagonal, the nominal power.
Please note nominal power is only for reference: actual power can vary a lot and should be measured on the field using your telescope.
