This faint obscure planetary nebula is located in the constellation of Perseus at a declination of +49 degrees. It spans almost 2 arc-minutes in our apparent view. I could not find distance or magnitude information for this PN. The image is narrowband (HOO) with RGB stars.
Two other images of this challenging object were posted on Astrobin this month by
@Jerry Yesavage (
here) and
@Bob Rucker (
here). They suggested that I give this difficult PN a try to see how it comes out with my setup under my skies. I find my result to be very similar to theirs. They obtained more time that I did on this object but their skies are brighter. Credit to these 2 men for their dedicated effort to capture this faint object under their bright skies.
Per Jerry's post, this PN was first observed on 9/20/2010. It is classified as an elliptical PN.
Like Jerry and Bob, I found that the PN is primarily HII signal with just a bit of OIII in the center.
I would have given this object more time but the sky forecast for my week is bad, as it often has been this winter, so I am moving on.
The faint PN-like object just above and right of PN G156.4+01.1 in my image is the galaxy LEDA 15704, also known as Weinberger 20. This small galaxy is located 270 million light years away and is 15 arc-seconds wide, which corresponds to a diameter of just 20,000 light years. The galaxy image here is from the RGB subs and I find it interesting that the galaxy shows up to be so red.
