Rosette Nebula

I found this to be a difficult object, but was able to sense the size of nebula, without seeing any details clearly. I used my Tak 100D with a 30mm Plossl (Vixen) and LE24mm EPs.

The Nebula appears to surround the cluster NGC 2244. My impression was that it was no so much a cluster, as an asterism of 6 bright stars.
https://en.wikipedia.org/wiki/NGC_2244

The whole region is rich with faint stars, as this is embedded in the Milky Way. This gives a 'white-noise' effect that makes the viewing of the nebula more difficult than it would otherwise be.

The Nebula looked more distinctly visible on the northern side of NCG 2244. I had been a little mislead by photos which show the brighter, round (flower) area of the Nebula. So this confused me when I sensed a fainter trail to the East. However, I have since found a map that confirms this observation.

Truth be told, I have always been a little embarrassed by the Rosette. Images are often featured and it is also marked in my Bright Star Atlas, so I thought it should be easy to view. I have tried previously to view it from dark skies when I had a 12" Dob, but felt nothing but confusion trying to determine what I should see. So, I am glad to finally see it, and I now realise that it is a difficult object to view.

I enjoyed your report Bob.

If only I could find a clear night! Also, astronomical twilight does not end here till about 11pm local daylight savings time. So, it makes for late night/early morning sessions way down here when trying to chase faint objects. At least we get some advantage in mid winter when twilight is over by 6.30pm.

Nice review Bob ..Saw this in a 100 ED I had once with 24 Pan ; though the nebulosity only really showed with an O111 Filter in this small aperture.

The Filter made all the difference near the city when it culminated and was basically invisible without it.
