A Christmas night Planetary/Open Cluster

Hi everyone.
I hope everyone had a great Christmas day.
With lots of cloudy weather of late got an opportunity for some imaging on late Christmas night. Using the Argo Navis it came up with Planetary NGC 2452which happened to be next to open cluster NGC 2453.

2x10 mins ISO 400 ,UHCS and uv/ir filters, MPCC, 10 inch f5.6 newtonian, hand guided, modded 350D. Seeing rather poor, impossible to get sharp star images. SW change had come through. Some cloud patches about.

Cropped from centre of much larger image

Interesting pair of objects.
Well done seeing the seeing was bad.

Good work Scott

I thought I was the only one out there Xmas night?

Feels good to know someone else was out there having a crack, especially in the conditions associated with the change

When I read the title of the post I thought you had imaged M46

What a nice little pair, I havent looked yet, but whats the mag of the PN?

PN is mag 11.9, size 31"

NGC 2452, PK 243-01.1, PN G 243.3-01.0
RA 07,47.4 DEC –27,20 MAG 11.9 SIZE 31”x24” CON Pup SKY 19 URA 320 MILL 0367
This PN was discovered by John Herschel on February 1, 1837.
Also known as J.H. 3100 & GC 1574.
Field Description: At 62.5X, faint, 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 100X, the PN is visible as a small diffuse disk with averted vision alone. At 200X, the PN shows up better. No central star is visible. Nice open cluster NGC 2453 is just north of the PN.
Observed at Navaho Flats on 10/15/90, 02/24/92 & 02/10/93 and at the water tank on 10/18/90 & 04/03/91 by Kent Wallace using an 8” f/10 SCT.

Another interesting pair is the OC N6124 and the PN N6153 in Sco. They are 75' apart. I like the mini Crux field around 6153.
