18.3Hrs, 2600mc, no filters, pier mounted AM5 carrying a FF65.  300s subs at gain 100.  220 x 300s over three nights.

Well done, mate! A very nice illustration of how no matter how clear our skies get, our view is always obstructed.

 

I'm loving the little nebulas in the galaxy at 100%. They remind me of when I first imaged NGC 346 and NGC 371 in the SMC…

Thanks!  There is a tiny side on galaxy at 10 o'clock left of the bright star on the far right of the frame.  Plate solving on Astrobin and Astrometry.net yield nothing.   Any idea?

PGC 63540. At least star field matches what I see.

Incredible!

Keep bringing these images. For those of us stuck way north never get to see all the southern treasures and you feed our hunger well!!!

That's a neat looking pic Zambiadarkskies. Thanks for sharing.

Nice image, Gilmour. 18 hours is a long time for Bortle 1. 

 

I was pixel peeping and something occurred to me, so I have to ask because I'm a little confused. You say no filters in this post, but your Astrobin page says Optolong IR-pass. If you indeed didn't use any filters, any particular reason why you chose to use 300 sec and gain 100? My similar scope, FRA400, starts to saturate stars at 120 sec and gain 0, which is about 7 times less signal amplification. Maybe that is the reason why the brightest stars look a bit funky?

[Zambiadarkskies]

Yep, I should have said no filter other than it/uv. I know the sensor window on the 2600 is one but I prefer to have a filter in the drawer for focus. I should have dropped the gain down to zero or even a negative, but didn't. So yes the very bigger and brighter ones are not totally 100%. As for choosing 300s, for me the longer the better. Largely due to my laptop which is struggling.

That is a very cool picture.  I wasn't aware of the IFN in that area.
