the Spider and the Fly,
first try at this dim object pair.... the fly, ngc 1931, on the
left and ic 417, the spider, on the right.
I was surprised at how weak this pair is, 11 ten-miinute subs
at iso 1600. When the sky is better I plan H alpha for better
detail.
Stars in the guider were cotton balls that bounced around, rms
error about 2 arc seconds with wild excursions as the wind blew...
In the larger views you can see 16.2 magnitude MP 3914 Kutogahama
forming a triangle with phi Aurigae and HD35520.
AT8 f/4 Newtonian piggyback
on the Meade classic 12 inch, Hapmod 350d controlled by Nebulosity
2.2, guided by the main tube at f3.3
with DSI pro mono and PHD. Processed using bad pixel removal,
flats, color balance and ddp in Nebulosity, Final adjustments
including
min/hipass enhancement, star color enhancement, GradientXTerminator,
and a couple of other things in Photoshop CS3....
sky poor and unstable, haze
and east wind with high thin clouds.. high level winds opposite
causing turbulance
enjoy peaceful skies
