NGC 1514 – Planetary Nebula In Taurus – the “Crystal Ball Nebula” January 2019 Observer’s Challenge Object

JANUARY 2019 OBSERVERS CHALLENGE – NGC-1514

I’ve observed NGC 1514 thrice with my 15-inch f/4.5 reflector, and it’s wonderfully complex.  The sketch was made at 216× with a UHC filter.  I may not have gotten all the lumps and bumps in exactly the right place, but it gives the general impression.   Sue French

Seeing was excellent, but with a 74% illuminated moon.  I set my 10-inch reflector in the backyard, using my house to shield the direct light from the moon.  Having no idea what to expect under these conditions, I started out with 57x, and without a filter.  It was easy to see the 9th magnitude central star, with some faint surrounding nebulosity.  I then went to 208x and a UHC filter, and the nebula really came alive!  The only two stars visible in the field, are two ~8th mag. stars…one to the north and the other south.  The nebula has greater concentration to the north, which can seen in my sketch.  The edges are irregular and uneven, and the nebula has a very subtle N-S elongation.

NGC 1514 in Taurus is sometimes called the “Crystal Ball Nebula,”  But I have coined the name “Herschel’s Revelation” as being far more significant.  This is the object that convinced Sir William that nebulae were real and not, as was the belief then, just masses of unresolved stars.  His profound insight came at seeing the clear separation of the surrounding nebula from the obvious central star.  Yet another of Herschel’s many amazing observations based solely on the visual appearance of an object in his telescopes.  Jim Mullaney 

NGC 1003 – Galaxy In Perseus: Observer’s Challenge Report #118 – December 2018

Notes and sketch by Sue French from New York:

I went out on December 4th to observe NGC 1003, which was my first clear, moonless night since October 30th.  Apparently the weather gods have a wry sense of humor, since this was my wedding anniversary.  We took out my homemade 254/1494mm Newtonian (10-inch f/5.8).  The seeing was fair, the transparency good, and the ground was covered with snow. 

The night was slightly breezy and the temperature 19 ºF.  At 68×NGC 1003 is a faintly visible oval near a 10th-magnitude star to its west-southwest.  At 187× the galaxy is nearly uniform in brightness, and a faint star appears along its northern flank. The galaxy looks more flocculent at 299×, and a slightly brighter region rests between the two flanking stars. The sketch was done at this magnification.   Sue French

We also looked at Comet 46P Wirtanen through Alan’s 15×50 image-stabilized binoculars.

I could’t use many subs, had some tracking issues and need to work on my declination axle motor to worm coupling. The tracking seems to bounce a bit N-S, and stars are a  bit bloated, so this is not my best effort.  The time was about 40 minutes for a total of 5 min subs only.  Mario
