Ngc 2736-
Herschel's Ray/ Pencil Nebula |
|
Info |
Ngc 2736 is located in the
constellation of Vela. Ngc 2736 is also
known as Herschel's nebula, first noted by William Herschel in 1835
while on a 4 year stint in South Africa. It is a Super nova remnant and
while in close visual proximity to the far larger Vela remnant,
from an optical aspect, astronomers are tending to believe it hasn't
any association to it. It is approximately 5L.ys long and at a
distance of 800 L.ys away. |

Notes/ Conditions |
Conditions- It has been a case of picking in between the
high cloud, waiting for clear breaks. When it's clear, it's windy. This
time of the year can be a challenge here. Seeing and transparency average
on all occasions. |
