Object name: PVCEPH
Designation(s): PVCEPH, 17,
I've been monitoring the nebula around PV Cephi (Gyulbudaghian's Nebula) since 2011. Each year changes are seen but nothing nearly as dramatic as when my images are compared to the POSS I and POSS II images. In the POSS II images it is nearly invisible in red light as a streak with a bit more even fainter features but in blue it is rather similar to the brighter parts seen in all my prior images so it was very blue back in the mid 60's when those were taken. But since they could have been taken a year or two apart this isn't saying much. In the 1950's when the POSS I plates were made the streak of red light was much stronger with little else seen. It was also seen in blue light but was much weaker so then the streak was quite red.
