60 minutes on a horse

[fwm891]

First visit to the stable this season. Here I've used my modified Nikon D5100 with a Baader 7nm Ha filter. There are 6 x 10 min subs with my 115 EDT APO frac on iOptron EQ45Pro.

Mono can be so rewarding.

Mick, Alnitak is spectral type O which puts it in the blue end of the spectrum - I'm shooting this in H-Alpha (red end) so Alnitak is quit dim there. If I shoot LRGB later then it will shine much brighter.

Of course,should have realised that.
