3rd October 2012ngc6888 Crescent Nebula in Hubble pallette
Ha, OIII, SII 8x10 minutes each, WO132 scope
The recently discovered Soap Bubble nebula is just visible in the lower left corner.
A nova was discovered on the 30th September.
MASTER OT J054317.95+093114.8 - new bright CV MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 05h 43m 17.95s +09d 31m 14.8s on 2012-09-30.78510 UT. The OT unfiltered magnitude is 13.4m (limit 17.9m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-11-02.73236 UT with magnitude limit in 'V' filter 18.8m.
This is the discovery image
This was not an easy object to image. The nova was very low on the horizon in the constellation Orion, and could only be imaged after 1am.
The magnitude is fading and was measured at 14.75

LDN889 is a Dark Nebula
Cloudy conditions - only managed 3x10 minutes in Ha

M31 Andromeda galaxy
10x10minutes luminance binned 1x1. Colour added from Ha, OIII, SII data.
On 8th July 2011 I obtained an image of a newly discovered nova in M31 - as shown in the right hand image.
It is easy to see that this was a transient object as nothing at that position is visible in the recent image.
