Having some fun - 4 months and back - first light at 6750mm fl

[NickK]

So I have the titan setup up on the Pentax 105.. with a 2x PM into a 5x PM.. effective focal length 6750mm - it seems my alignment is rather good!

Pity that the atmosphere is a bit bubbly, especially at its current elevation.. here's a single exposure.

Yes I've now cleaned!

A couple more:

670mm fl (native focal length f6.38)

1340mm fl (PM 2x)

Great shots Nick can't wait to see the close up with the sensor clean

Nice shots at prime focus, Nick!

Wowsers, 2x powermate double stacked with 5x powermate for the top image. That will certainly show up the dust!!

Nice experiment in pushing the focal length

I think foil is ok for normal shots but I think it's not quite good enough for long fl imaging!
