Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Site classification: rural

Limiting magnitude: 7.2 (zenith)

Seeing: 3 of 10 - pretty good

Moon up: no

Instrument: 20" f/5 Tectron truss-tube dob Newtonian reflector

Magnification: 420x

Filters used: None, DeepSky

Object: vdB 152

Category: Reflection nebula

Constellation: Cep

Data: mag 8.8 (star) size 12'x6'

RA/DE: 22h14m +70o18

Description:

Easily found in a field due E of beta Cep, surrounding and near the lovely, bright double HD 210884 (mags 6 and 8, separation about 1', PA 100o, colors white and pale violet). This double is due S of the "bowl" of a neat naked-eye asterism shaped much like a spoon, just NE of beta Cep. VdB152 faintly surrounds the pair, but is especially prominent around two nearby mag. 8 stars which form a long triangle with the double, about 10' to the W and WSW of it. (As a matter of fact, the greater brightness of the haze around these stars vs. the brighter double-star, is what initially confirmed for me that this nebulosity was more than eyepiece dew!) The N mag. 8 star (which is either GSC 4467-0434 or SAO 10287?) shows very obvious nebulosity to the N and W, little or none to the E, and just faint averted-vision haze to the S. The S mag. 8 star (HD 211319) is faintly bathed in haze requiring averted vision to see all around. Slight brightening in the sky AWAY from these stars was apparent, especially to the N.

Petteri Rajanen

Petteri Rajanen (Kauppi, Tampere, Finland) observing with a 8-inch f/5, writes in the The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "Observed at x38 using a Lumicon Deep-Sky filter, but visible only from time to time. Small, with uniform brightness. Edges rather well defined."
