The last dark sky window was not very productive for me due to cloudy weather. But, there were a few good first-time catches. And I'm getting very close to the end of my six year quest to screen every DSO brighter than magnitude 12 for my personal "Best DSO" list!
All observations with the 16"f/7 Zambuto from my back yard, 6 miles north of Prescott, Arizona. Yellow Zone light pollution (Bortle 5 trending Bortle 6). Eyepieces used: Leica ASPH Zoom, Mod 3C White Phosphor night vision eyepiece. Some of the larger nebula were viewed with the Mod 3C and telephoto lenses.
NGC 5466, Globular Cluster, Bootes. Apr 24, 2019, Z16, Home: Looks like a very rich open cluster. Excellent view with NV. Much fainter in the Leica.
M 102, Spiral Galaxy, Draco. Apr 24, 2019, Z16, Home: Spindle Galaxy. Looked good in both Leica and NV. The surface brightness is high enough that you don’t need maximum reduction I got good views at .7 X and prime focus and even was able to use the 1.5 Barlow to good effect. Appears to be a slight nuclear bulge, very prominent dust lane amazing!
M68, Globular Cluster, Hydra. Apr 24, 2019, Z16, Home: Too many stars too count, I quit after three dozen. Very nice view. Switching to the Leica it was a mottled and textured ball with perhaps six stars visible. Looking into the light dome of Preskett took it’s toll.
M83, Spiral Galaxy, Hydra. Apr 24, 2019, Z16, Home: Very bright and easy to see, bight core, bright glow surrounding it. I was hopeful that it would show nice arms like M 51 but in the sky glow I could not bring out any spiral details. Tried a focal, prime focus, and long pass filters to no avail. No luck in the Leica either. Need darker skies for this one.
Sharpless 2-27, Bright Nebula, Ophiuchus. May 1, 2019, Z16, Home: Zeta Ophichi Nebula. Huge sprawling complex, lots of texture. Brightest portion west of Zeta. Well framed in the 50mm Canon.
Sharpless 2-12, Bright Nebula, Scorpius. May 1, 2019, Z16, Home: Provisional score of 4. Nice bright patch of nebulosity in the Canon 135 telephoto. Probably would be perfect in the Canon 300 mm or the Takahashi Epsilon.
Sharpless 2-13, Bright Nebula, Scorpius. May 1, 2019, Z16, Home: Another provisional score due to limited telescope field of view. Very bright and easy to see spilling out of the field, appears to be involved. Lots of great contrast here may become a 5 through a wider field scope!
Sharpless 2-15, Bright Nebula, Scorpius. May 1, 2019, Z16, Home: Provisional score. This one is just too big to frame with the 16 inch Zambuto. Entire field filled with nebulosity I’m sure it will stay at least 4 when I come back with a wider field scope.
