Processed up about 2 1/2 nights of data on a feature known as the Cygnus Wall, a portion of the rather large North America Nebula (NGC 7000). This is a turbulant star forming region about 2600 light years from us.

Processing experiment with my #Unistellar Odyssey Pro - captured using 'science mode' versus 'enhanced' mode, to better control on exposure/gain, and to get full native resolution vs 2x2 binned images. One hour integration (900 frames) processed in PixInsight, and pretty picture of M33!

NGC-7331 (and about 7 of his galactic buddies) - a very similar galaxy to our Milky Way (even though more recent research has found our galaxy to be a barred spiral) - shot last night in LRGBHa.

Now that we're getting in to it being almost Fall , this target seemed like a good choice, with Halloween on the way.
This is LDN-1306 - Ghost Of Cassiopeia -which really DOES look the part! 🙂

Did some galaxy shooting last night - this is M33 (a.k.a Triangulum Galaxy), the second closest major galaxy to ours (after Andromeda).

Shot of LDN-1218 (sometimes called the Cave Nebula) in narrowband (SHO) with RGB stars.
This is a 'dark nebula' in front of a brighter emission nebula, which is why there are so many fewer stars in the lower left portion of the field (just some nearby ones), compared to the rest of the field.

The band playing "Fortunate Son" might have been the best part of the whole parade. In case you don't know the lyrics, here they are. A perfect gift for a flawed man.

Do find the whole #WokePope thing ironic - have folks actually READ 'The Sermon On The Mount'? Not religious myself, but good words are good words...

Proof this guy is full of SITH.
In Star Wars. those who have embraced the Dark Side of the Force wield red lightsabers. So, in other words, perfect.

Another observation project of another SPP (short period pulsator) - specifically an RR Lyrae type variable. This one is TZ Aur - a star whose brightness cycles every 9 hour, cycling up and down in brightness by a multiple 3.6x each time.

Some more clean up and reprocessing on my BH Aur observation project - really not a bad result for a 114mm telescope from my back yard in Rockport, MA! :)

Trump: Gutting National Parks—And Hiding the Evidence
National parks hit 331M visits, but Trump officials don’t want you to know. A leaked memo bans the Park Service from promoting the numbers—while firing rangers, closing visitor centers, and cutting safety.
This won’t go well—we love our parks.
