Object of the Week July 23rd, 2023 – Sharpless 2-27 in Ophiuchus

[ScottH]

Hello Scott,

checking it with my notes, the bent ribbon well visible through the H-beta filters, as marked with the large oval, is home of the Lynds nebulae:
LBN 39 (east of the oval), LBN 32 and 35 (NW of the MBM 139 molecular cloud), and LBN 20, 21, 22 (south-west).

Clear skies,
Jiri

Thanks for that, Jiri. Where a Lynds Bright Nebula ends and another begins isn't easy to see or draw!

By the way, Victor van Wulfen has found (and SIMBAD agrees) that what you labeled as the open cluster Do 23 on your drawing should instead be Do 27 (with the "Do" standing for Dolidze). Here is the excellent chart he drew up and labeled (https://clearskies.eu/csog/downloads/dsfootw2023/#30).
