Notes: This December is starting out rainy (good), and cloudy (not so good for imaging) ... Had one night between clouds, with so so seeing, and imaged two small Planetary Nebulae. See PK 147+4.1.

PK 133-8.1 is listed as 18 arc seconds in size, but looks stellar in my image (and online images). Similar in appearance to PK 45-2.1.

The CDS data query for PK 133-8.1 returns V* V 471 Per (Eclipsing binary!).
