Low-cost lens alternatves: MC Rubinar 8/500 test
Just a test, before glass relaxing, from Mt Waverley light polluted skies... The first image is stack of 8x1min exposures at 1600ASA, on EQ6, unguided.
The lens performs quite OK as it is now, but the fine details (on the full resolution image) are missing, of course .
The 200% detail from Upper Right corner (from un-processed RAW) is attached, to illustrate the field flatness performance (field is very flat, as there is no difference in stars shape from those in the centre).

Reason: clarity and more data
