IC 2948 - chicken gizzards

[markas (Mark)]

This image was shot between dusk and moon rise in somewhat extreme conditions: SQL 20.7 - not great; seeing ~3"; ambient temp 18C, RH 99.9% for the whole 2 hours' exposure.

With such a warm saturated atmosphere I didn't expect too much..... fan going flat out, window heater flat out. Only had time for RGB 40 min each.

ASA10N at f/3.6; G3-16200; Astrodon filters; ASA DDM60. The image is approx 30% area crop - FOV is about 54' X 48'. Processed in Pixinsight without deconvolution or noise reduction. Synthetic L from all the colour subs.

Nice rich colours, Mark.

Really lovely colour Mark

Site conditions can really play havoc with a powerful system like yours. I used a similar outfit to yours in a crap location for 18 months and started to think my gear was below par , then I moved...and coupled with better image scale and seriously improved site conditions, the same scope produced markedly different results:

Inner Newcastle NSW - sea level, coastal, moist skies and heavy light pollution along with very regular crap seeing

Semi rural Canberra 600m ASL, dry, inland, generally good seeing conditions and pretty dark skies

Michael, Tim and Rick,

Thanks for the comments. I guess I'm lucky to also have access to a higher (680m), darker site which can be very cold with high RH, but never warm with high RH.

Still, this was a good test of the camera window heater effectiveness!
