Well I have just had a practice zoom video meeting with Davey T on my laptop, and although we both faffed around initially we did get to see and speak to each other, so hopefully all will work OK on Sunday.

Thanks for the info. I will take a look at that video as I missed the presentation.

I will set my alarm for Sunday evening. :)

That's good news.  I had the same problem yesterday with a Google meet meeting - even though 10 minutes before, using the same camera/speaker setup, I had a skype call.  I ended up using my mobile phone for  audio 🥺  BUT, and this might be useful, when I switched from Chrome to Firefox it all worked fine.  Is there an irony in that Google meet won't work with Google's own browser 😏

I’m very much looking forward to Nik’s  talk this Sunday - I don’t think I have ever attended an image processing talk where I haven’t taken something useful away as there are so many different ways of doing things. Roll on Sunday 👍

@steppenwolf  Sorry I missed your live talk Steve, you may know I was watching but couldn't hear anything.  Have now watched it on the recorded version. 

It was so interesting to hear your talk  because I give similar talks to local groups, such as U3A and photographic groups etc, and some to beginner astrophotographers, so it was good to hear much of what I say pretty much repeated (so I know I am doing it right).  

I did learn a couple of new things from it such as checking the sky background in Curves, as I tend to just judge it, and focussing widefield images not in the middle.  

Great stuff and great idea SGL. 

Thank you.

Carole

@carastro I’m sorry to hear that you had audio issues but hopefully you will have resolved these for Nik’s talk tomorrow.

It’s always useful to have confirmation  that you’re doing things correctly but, one of the fun aspects of AP is that there is plenty of opportunity to explore your own way of doing various processes.

With regard to background brightness, I think it is quite important to avoid an ‘inky black’ finish as this can look quite unreal. For what it is worth, I use a sample of size 3 x 3 (set on the pipette prior to invoking the Curves tool) and several times during the ‘Levels’ stretch, I call up Curves just to measure (but not adjust) the background level.

I'll keep everything crossed for you  Carole, l ordered a Microphone from eBay, but it hasn't arrived yet, so, all I can do is watch and listen.     Looking forward to it though.

Ron.

Steve's talk last week was really good as its looking  like I might miss the beginning so is it recorded so I can catch it later?

As a bit of a luddite I like to get setup in advance... There is also a Zoom App for the iPad available.

With the App, you can use Settings to turn off your microphone and inhibit your video (if you want) - I have, I may have a glass of wine - who knows!

Although the meeting starts at 7:30pm, you can sign in early and wait for the organiser to start - I'm signed in.

I have a very slow internet connection.  The video just got more and more behind the audio and then everything froze.  Had to give up 😧
