Helix in HA.....not impressed
Hi Guys,

Was imaging the Helix in HA to see how far I could go....I think the ISO was too high with too long of exposures....I am not sure...I was expecting more with the same exposure time of my recent colour Helix but was expecting to see more of the outer ring with 20 Minute exposures F8.

Anyway here it is....5 x 20 minute guided exposure ISO1600 sensor temp 3°c
HA 45NM filter

happy with the guiding for such long exposures.
Look no defraction spikes...lol
