Description

39x8mins (5h12m), astromodded canon 50d@iso800 + CLS filter, with canon 100mm f/2.8 macro @ f/5.6.

50 darks, 50 bias, 50 flats. calibrated, registered, stacked and processed in pixinsight 1.6.9.

slight crop, but lower right hand corner is the corner of the sensor.

somewhere along the way i blew out the bright stars. not sure what happened there.

this is first light for this lens, in my hands anyway. at f/4 it still seemed like there was a lot of dispersion and loss of focus at the corners, so i stopped to f5.6. i guess the cone area needs longer subs/more integration time... it is very faint. perhaps i should have stayed at f/4.
