More 8" reflector stuff over two nights, 18th. and 19th. April. Lucky the first night, not so the second with haze preventing focus aroiund 03:00; the second set of m5 was curtailed. Finished night one with just 2 (two) of a planned 18 on m56. Ah well...

Finally put the refractor to rest and got out the 203. Still galaxy season so after the galaxies swung west, the big globulars rose. Good seeing with guiding rarely above 0,4"rms.
Big callout too for Frankin at setiastro.com. His SetiAstroSuitePro software should take most of the credit...

With apologies to all the residents of m94, note to self to do this properly. It needs loads more time. Hopefully then there'll be colour as well as the outer halo. Alas, the calima hit around midnight, after only 90 minutes.

Not the same session. One with sv220, one without. Always wanted to get the Ha of m82. This seemed to do it without the usual processing fight...
