Description

I already shoot this object last year with the same newton LACERTA 250/1000, but I had collected only 2hours ... this time, the objective was to do the maximum to get good subs (with small FWHM, I keep only the FWHM under 2,3''), and enough exposues on all the filters to keep noise at a low level.

With my new mount :-)

I like this version much better !

9 nights in July y : 16, 17, 19, 20, 21, 23, 25, 26, 29

68 SII Subs @300s (gain 139, -20°C)

116 OIII Subs @300s (gain 139, -20°C)

100 HalphaSubs @300s (gain 139, -20°C)

Total => 284 subs @300s = 23h 40minutes
