A PN I bet you have never seen

And probably still can't!

Conditions cleared last night here, but the sky - especially LP - was a strong "Meh", but decided I had to image anyway. I have a list of "just to say I've imaged it" targets, and a couple are around Crux, so went with NGC 5315 PN in Circinus.

I knew it was SMALL. I didn't think it was THAT small

This is the HST version of it: https://en.wikipedia.org/wiki/File:NGC_5315HSTfull.jpg

This is my version (3hrs of 10 min subs)>
Annotated: https://www.astrobin.com/342081/0/?nc=user
Full image: https://www.astrobin.com/full/342081/0/
Close crop (yes, the pinky "star" at centre) - 400% zoom : https://www.astrobin.com/full/342081/B/?nc=user

Don't blink, you'll miss it! I am not going to revisit it. I'll leave that to people who image at f/15 I think I need more aperture and resolution...you know, kind of like Hubble or La Silla....

Indded, such that in the combined image PI spat out, I actually initially thought I was a little off target and thought the PN was a brightish red star off to the right and up a little! Until I plate solved it and went, "Oh"

Yup. NOT going here again

Are you sure you aren’t just off target and confusing PI with its plate solve?

Besides, Astrobin plate solved it and agrees

this is the "object" I initially thought was NGC 5315. I will run it through plate solving online again and see if it can name it, because it looks like a PN to me. This is a little ways from 5315. 400% zoom again.

Can I claim discovery?

OK astrometry.net found nothing: http://nova.astrometry.net/user_imag...7457#annotated

I hereby name it the Lubov PN in honour of my mother in law

Perfect target for your system.....

I found it without using the annotated version or seeing your crop too

Can you have a crack with the Newt Mike - your FSQ will show the same field/scale as mine pretty much. You can see I didn't even bother processing it...no colour boost, noise reduction...nada. Just straight out of PI with a background neutering and colour calibration.

Go deep or go home

You bunch of monkeys could at least give it a thumbsup

Yep. I can just BARELY see any detail (lower left side). Otherwise, it's looks like a star to me.

Might back off the stretch a bit and see if I can see the mag. 14 central star.

Haha, no , hot pixel!

Sometimes it's fun to image the tiny ones. Shows just how deep space really is

Alcohol aberration more likely
