Andrea, I use the Astronomic UHC filter for galaxies and find that I get good contrast with that filter from the city.

Interesting night here under Bortle 9+ skies in downtown Ottawa last night ¡
Really bad transparency (just ahead of a weather front)¡ galaxies like NGC 891 were barely visible in DS432m + UHC on 8¡± SCT ¡ yet I snapped the best
image I have ever captured of M42 using the DS10cTEC + NBZ on EVO50 refractor (between rooftops, trees and electrical wires !!!)..?
I was so pleased with it that I have posted the raw image and its processed equivalent ¡ None too shabby for a 2¡± scope downtown !!
I also had a nether fo at NGC 2244 (Rosette) ¡ and was none too displeased.
While galaxies didn¡¯t do too well with the 432m last night, M1 showed up very nicely with lots of internal filament detail.
Conclusion ? : ?bad sky conditions affected the type of light coming in from galaxies differently from the type of light coming in from bright nebulae.

Re: Event: OAOG Gabfest - Thursday, November 17, 2022
#cal-reminder
Hello all,
I'm unable to make the gabfest tonight. ?Not sure who is all going, but would there be interest in an impromptu mini-gabfest next Thursday?
Don't forget the Leonids tonight and tomorrow night!
Cheers!
Pierre

Re: LEONID METEOR SHOWER ALERT
Hello all,
I wanted to add that this may be the most active year for the Leonids (assuming that the prediction for the outburst is correct) until the 2030s.
Lets hope for clear skies!
Pierre

LEONID METEOR SHOWER ALERT
LEONID METEOR SHOWER ALERT:?
Earth is approaching the debris zone of Comet 55P/Tempel-Tuttle, source of the annual Leonid meteor shower. Forecasters expect a minor peak of 15 meteors per hour on Nov. 17th (~2300 UT), followed by a more intense peak on Nov. 19th (~0600 UT). How intense???range from 50 to 200 meteors per hour. The possible Nov. 19th outburst is associated with a dense stream of debris ejected from the comet in 1733. Its timing favors observers in the eastern half of North America, who should be alert for meteor activity this Saturday morning between 1:00 and 1:30 am EST.

Re: Giving talk this Friday at RASC meeting
I apologize to anyone who tuned in for my presentation and didn't get to see it.? Last night's meeting was jam packed full of content and was running over time so I agreed to have my presentation bumped to the December meeting.? I will in fact have two presentations next month as I was already scheduled to present something else next month.? My two talks are called:? "A Report from a Beach Bum Astronomer" and "Newton and His Dang Rings".? I will post the new link to register when it comes available.? See you next month!

Good afternoon all,
If you are interested in hearing about what I've been up to astronomy-wise over the Summer, you can tune in to a talk I am giving tomorrow night at the monthly Ottawa RASC meeting.? It is free to attend, you just have to pre-register for the ZOOM webinar in
advance.? The link to register is below.
Cheers,
