These are 3 interesting, albeit difficult objects in Taurus, all lying very close to the Taurus Dark Cloud.

PK 174-14.1 - PN - vf, ps, looks somewhat elongated. I'd love to find a photo of this to see if my "elongated" suspicions are correct. Best with OIII, next best is Orion UltraBlock, followed oddly by Lumicon Deep Sky and trailing behind is the Lumicon UHC. Strange indeed. It's also visible with no filter, but far more satisfying with.

IC 2087 - Bright Diffuse Nebula vf, vl, quite oval in shape. Best without any filters, though the UltraBlock seems the best of all the filters. You might have to "wiggle" the scope a bit to get this illusive object to show up.

B222 - Inky black region surrounding, and just east of, an 8th magnitude star. My best magnification was 120x.

Has anyone seen any of these?

Hi Kent,

I've seen PK 174-14.1, PN G 174.2-14.6, aka Haro 3-29, RA 04,37.3 DEC +25,03 MAG 15.3 SIZE 20". My observation was using a 20" f 5.0 Starsplitter on 10/20/98 is a follows:

At 134X & 169X, a diffuse small disk requiring the O-III filter and averted vision. Good response to the O-III & UHC filters. No response to the H-B filter. At 254X, could see the PN with averted vision alone as a very faint, diffuse disk, requiring the UHC filter to identify it as the PN. Identified the field in the SEC finderchart.

Also my SEC list has a positive observation of this PN by Steve Gottlieb and Jack Marling.

This was a pretty tough object in my 17.5" at 105x, only seen with an OIII filter (no record if other filters were tried - this from 15 years back). I only recorded it as "small and round" and the image in the ESO-Strausberg catalogue appears to be a perfectly round disc.
