Glenn,

I think we may have one scheduled at James River State Park. I’ll call Marty to verify this and let you know. Thanks for spearheading our Caledon dates. If there are others reading this message who would like to help Glenn with sponsoring star parties at Caledon please let him know. The dates he has proposed are those where he has committed to being there to represent RAC. If there are others in the club who can be at Caledon to represent RAC we might be able to get back to having monthly star parties there.

Re: M81
With only 2hrs those dust lanes are already emerging. That is a great start to galaxy season. I’m in Costa Rica for the week and brought my Seestar with me for fun and it is fun exploring at a totally different latitude.?

Re: Potpourri of planets
开云体育I tried getting the planets last night. 3 were down in the trees. Wound up getting mars and Jupiter. Watched lo’s shadow transit across the surface.?On Jan 26, 2025, at 8:12?AM, Brian Barbre via groups.io <brianwbarbre@...> wrote:

M81
Dear RAC, With galaxy season almost upon us-I wanted to try M81. Unfortunately didnt get enough time with the blue filter and clouds played hide and seek during the red and green sequences. So overall not the result I was hoping for. But here it is anyway. Had to crop tightly on the galaxy as there was a bad gradient from the clouds. This is about 2 hours total integration using BVR filters and the 10" RC with QHY 294 M pro Myron |

Re: Medusa Nebula
开云体育?Brian,? Yes during the Red Giant phase the star undergoes instabilities arising from the core. These result in pulsations and mass loss as the outer atmosphere of the star is pushed away. Each pulsation strips away more and more of the stars mass until eventually the intensely hot and dense stellar core is revealed ( the white dwarf). Its prodigious UV radiation causes the hydrogen that was shed during the mass loss phase to light up. That creates the shell we see around planetaries.?

Re: Potpourri of planets
This next period of time will be strange having Saturns rings edge on. It’s crazy how much the overall luminosity dips when it’s just the planets surface.?

Re: Medusa Nebula
Is the nebula itself outer shells of the white dwarf that were blown off??

Potpourri of planets
Dear RAC, CAS and Friends, Tonight ( January 25, 2025)I spent some time imaging the planets with my 12" LX-200 at f/20. I used an old QHY 290C webcam and 2x barlow on the scope. The seeing was not very good as will be evident when looking at the pictures. For Venus and Saturn in particular-their low altitude in the sky made matters worse. The images are all at the same scale which allows for direct comparison of angular size. Hoping for some better seeing next time! Myron |

Medusa Nebula
Dear RAC,
Tried a very faint planetary nebula last night. Here is 3 hours of integration using BVR filters to simulate Blue, Green and Red. 1 hour each filter. Cropped slightly onto nebula. Note the intense blue central star. This is actually a white dwarf. I used the 10” RC and QHY 294 M pro cons camera on Station 2. |

Re: Imaging Jupiter
开云体育? That’s a pretty nice image David. Planetary imaging does require a lot of attention to detail and has its own learning curve. I too am still climbing and turns out we were imaging about the same time. I’ll send out my image later tonight after work. I’m still not happy with it- I want to try to get better color balance.?

For sure. I’ll be at that concert. They are always open to the public and usually free of charge. I assume the ellipsis is gmail??
