Image Description and Details: StDr 35 is an extremely faint potential planetary nebula discovered my Marcel Drechsler and Xavier Strottner.
It has an angular diameter of 960 arsecs.

WeSb 1 is a very faint likely planetary nebula.
It has an angular diameter of 185 arcsecs.
Recent research shows the central star of the planetary nebula (CSPN) has prominent deep and aperiodic dips in brightness.
The light curves show brief periods with up to 100% of the light flux dropping.
This resembles transits from a dust/debris disk.
Evidence suggests that the CSPN is a binary star system, or a symbiotic system inside an evolved planetary nebula, both of which are rare objects.
