Tiny, but quite interesting planetary NGC 5307
As the previous night was a total write-off, with the sky plagued by clouds after nearly two hours of my being out observing, I ended up postponing looking for it, soon after observing globular cluster C84 (NGC 5286, previously observed in 2011 and 2019), as it is momentarily mentioned as being nearby by Stephen O'meara on his book entry for the aforementioned 84th object in the Caldwell catalog - a far more conspicuous DSO which, as a consensus, is mostly neglected because it's overlooked in favor of neighboring, gigantic, "the-mother-of-all-globulars" Omega Centauri! (just 5° NW)
So, last night I star-hopped towards the nebula for about 15 minutes and, after spotting it, I realized that higher magnification was in order, so star-like it appears at low magnification; so after zooming in on it still with my jack-of-all-trades Baader zoom EP up to the 8mm mark (click), I decided to use a 1.25" 9mm orthoscopic EP, coupled with my ageing (rotting, TBH) Lumicon OIII filter, and noticed that this particular accessory wasn't actually doing the rather elliptical star's hollow, gassy shell any favors.
What wasn't my surprise when, upon returning to the zoom EP (now with my 2" UHC filter in tow), I realized this filter was actually providing me with better results than with the ionized oxygen one! I guess that consarned (excuse me, Rod!) rot is definitely taking its toll on the now-vintage Lumicon.
Fast-forward a good 15 mins and I didn't succeed in accomplishing the mandatory central-star find, as not even immoral 428 times (I know!) of magnification on my 12"-dob, helped me spotting the 15.4-magnitude white dwarf!
Advance another measly minute, and some wicked clouds my way came, forcing me to call it a day.
Well, whenever our southerly "winter" gets this mild (nearly 70°F!), clouds are an unwelcome flipside to it - I'd much rather having the cold* along with the ad-hoc
clear skies, thank you!
*Well, anything less than 50°F over here in Brazil, and we call it that!
