Askar 0.75X reducer

I really like the way this reducer mounts inside the scope. There is no light leakage or impact on imaging train! Once installed you do need to workout back focus which is a shame because without it there is no need to calculate backfocus. One thing I noticed is that according to plate solving data this reducer seems to be 0.789 and not 0.75. This affects the backfocus. I used precisely 55mm backfocus as indicated in the instructions and online BUT I had to adjust backfocus slightly. So in the end there might be some tweaking.
