The Celestron Omni CG4
This scope allows access to dimmer asterisms and open clusters (requiring high magnifications as well as
I scanned the Interstellarum Atlas charts for appropriate open clusters and asterisms in Cygnus and came up with a couple of Dolidze open clusters to start off this first light.
- Dolidze 36 (Cyg,
OC, chart #17 right) – NEW; using 160x, I see 19 stars ranging from mag. 9.5 to 12.1, with the five brightest stars forming a rectangular pattern.
- Dolidze 1a (Cyg,
OC, chart #17 right) – NEW; using 200x, a pattern of 7 stars ranging from mag. 11.4 to 12.5 in the form of a snaky line with an arrow tip at one end. Interstellarum plots a “Do1” and a “Do1a”, cluster while the Dolidze Index lists a “Do1”, “Do1b” and a “Do1c” – non-contiguous parts of the same cluster. I’m treating them as separate clusters. NGC6888 or Crescent Nebula – using 69x and OIII filter, nebulosity visible with averted vision.
- Jupiter – using 200x, got the clearest views I’ve ever seen from this planet from any of my scopes that I can recall. Besides the equatorial belts and the southern zone, the shadow of Europa was present along with the
