ASTRO: Bubble at 1.5 hrs under exceptional seeing
from Friday night: no moon exceptional seeing conditions
I measured 1.88" stars in 15 minute guided subexposures! http://www.narrowbandimaging.com/ngc...s4_ha_page.htm FIT data included this time processing was simple stretch and curves; no further processing image scale for the FIT is 0.453"/pixel roughly apologies if this appears twice: my earlier post seems to have died
