Eta Carina nebula

Eta Carina is one of those objects I thought I'd never see unless I took a trip to the Southern hemisphere. But exploring the planetarium software one night I realised that it actually climbs to 15 degrees above my Southern horizon in the wee hours of the morning at this time of year and decided to have a go at imaging it with my WO Zenithstar 103/QHY168C combo. Crucially, I also used an STC multi-spectra filter and this cut through the heavy light pollution on my southern horizon. Visually, with good binoculars, I could only see stars down to around mag 6 or 7 and there was no hint of any nebulosity but the first frame downloaded from the camera clearly showed the nebula. The seeing was very poor at that low altitude but nearly 4 hours of 1 minute subs stack up to quite a pleasing image.

All post-processing was done with PixInsight. Image sequencing and capture was controlled via SGP and PHD2. Mount was an AZ EQ5-GT.

Taken from Prachinburi, Thailand.
