On 23 Apr I looked at 19 PNe with a 16" GSO Dob and a TV T6 7mm Nagler (260 times) between 10pm and midnight.
The faintest PN was NGC 6337. NGCs 2818 and 2899 were also faint.
NGC 2867 and NGC 5882 were small.
The other PN were NGCs 2438 (in M46), 2440, 3132, 3195, 3242, 3699, 3918, 5189, 6153, 6302, 6369, 6563, IC4406 and Menzel 2.
NGC 3699 has a dark lane through it.
NGC 6153 forms a mini cross with 3 stars.
NGC 6369 has a dark core.
These images are from wikisky.org. They have a 14 arcmin field.
