A Sydney Lockdown Trifid.

Hi all,

I've been trying to capture subs on this one over the last fortnight but (as ever) I didn't end up with as much integration as I'd have liked.

We've had pretty good weather over the last fortnight and I've been trying to split my time between planetary and deep sky. Being in Bortle 7/8 skies I'm loathe to image when an object gets below about 40 degrees as you can really see how much more murky the sky gets at lower altitude. I planned to collect more subs on this during a clear evening on Wednesday but my mount started playing up with power problems .

I'm still not completely happy with my guiding & the resultant star profiles so there's still plenty of tuning needing done (after I work out what the power problem is).

Telescope: Skywatcher MN190
Camera: ZWO ASI2600MC
3.5 hours total - 2.5 min subs at gain 100.
