Description:
(First observation through 4” refractor)- this object in Hydra (mag 12.6v, 
275”x260” across) a slight step up in difficulty from Abell 31, but still 
definitely in the top 10 easiest Abells. It’s main claim to difficulty is the 
magnitude 7 star that is superimposed on the SW edge. An easy catch in my 18” 
when I first saw it several years ago, but would the refractor be able to 
handle it? On 12/21, I gave it a try. Once I placed the refractor on the 7th 
magnitude star, I popped in the 19mm panoptic (37X) and OIII filter to see 
what I could see. The nebula was easy, and I was able to hold it in adverted 
vision. It looked as if some of the light from the magnitude 7 star had 
spilled out and formed a circular puddle to the northeast.
