ST8300 first light - nb Gaby Mistral

Gday

Just a quick and nasty nb composite of Gabriel Mistral taken between clouds at Leyburn on Fri night.

Found the ST8300 to be very sensitive (although i mucked up by taking the Ha for this binned 2x2 after playing around with a UHC filter before exposing Ha). Sensitivity at first use appears to beat my ST10 - nothing measured just a gut feeling. Used an Astronomik 6nm Ha and took a 6 minute Ha and it was way overexposed so I knocked it back to 3 minutes and it still needed a bit of processing to bring down her overexposed forehead. Took some SII (5 x 6 min)and OIII (6 x 6 min)between clouds but nowhere near enough. I enhanced the SII and OIII as much as I could to get something for all the trouble - but I know they are weak.

Anyway it shows potential (even at a quarter of the resolution).

Scope - ED120 Black Diamond
Composed as Ha (10 x 3), Ha (10 x 3), SII (5 x 6) and OIII (6 x6)

Waiting for the Astrodon LRGB to arrive to try it agin.
