Its litte to tuff observe here in Sweden now and temperature at -25C and allot of snow.

I’ll just noted I had 10 years in hobby. Started from zero knowledge.
Where the 30” telescope are its not to good skies as light polluted citys around but I had seen near SQM 21.6 at zenith but to Stockholm and if ex M33 is to south I barley can see it, but I found a spot I would like to see as I noted a ’ring’ and its not to far away from NGC 604.

Found it in Simbad but not on Sky Safari.

Number is XMMU J013433.6+310021 and has the visual magnitud at 14.8 so one would see it with big app and good sky.

-Has someone see this object ?

I'll check my notes later to see if I've actually observed it, but the H II region lies in the OB association cataloged as "A45". And the H II region was first cataloged as "Mayall & Aller 9a" (MA9a) in 1942 and much later as "BCLMP 650".

So a filter is needed to maybe see it.
-Maybe this ’rings’ is not that uncommon on galaxys.

I checked and my notes read "At 278x in 10-inch was a small diffuse glow that was more evident than I expected it to be." No filter was used. And as you'll see in the image below, Hakann, it's not a true "ring" nebula.
