Clear skies - 17/10/22 was created by flt158
www.met.ie are promising clear skies for Monday night 17th October. 

It seems a good night to set up our refractors, reflectors, SCTs or binoculars. 
Whatever you have!   
With the Moon out of the way, I promise I will try and see V382 Cassiopeiae once and for all. 
If I don't - I won't bother with it again.
I'm firmly convinced that this carbon star is fainter than +13.0. 
I do have a printed Guide 9.1 DVD map at the ready. 

Clear skies, everyone, from Aubrey.

Hi Aubery, let's hope for a clear one. I'd like to help you out with this star V382 Cas, I can image down to magnitude 14.5 on a really good night, i'll try to image the filed, let's see how I get on...

This is a very seldom observed star, the latest observation in the AAVSO database is from last December

Excellent to hear from you, Keith!
I will be utterly delighted if you could produce an image of V382 Cas. 
I wonder if you could include 3 Tycho field stars. 
Here are the designations and their magnitudes. 

TYC 3662 2558: 11.0. 
TYC 3662 2542: 11.5.  
TYC 3662 2485: 12.3. 

There is another field star that has a very strange designation. 
It's called 3UC297-012796. It sits right next to V382. 
Its magnitude is 12.7 and I have observed successfully. 

Not to worry if you cannot, Keith. 
There is no pressure. 

You see, I firmly believe that V382 is fainter than any of the.above stars. 

Thank you for the AAVSO link. 
I am very familiar with it. 

Clear skies from Aubrey.

Hi Aubrey, I got it ! Fortunately the skies cleared and the winds died down. I managaed to get a 30 second exposure at ISO3200 to go deep. I have used the AAVSO 'E' chart for this star, I reckon photographically it's at magnitude 11.9 !

So it could be brighter than you think. Unfortunately, my image hosting website at flickr is down at the moment so I can't post a full resolution shot, I'm afraid all I can do for now is show you a very much reduced crop

I have marked the star with an arrow

Keith.

 Thank you, Keith, for your sensational image!
You definitely got the right star. 
Congratulations!

Sadly I looked and looked over and over again and again using each of my eyepieces - even my most powerful ones. My Radian 3mm gives 374x. 
But there was just no sign of V382 Cas. 

Maybe I will try again another time. 

However I had an excellent time observing Jupiter later in the night. 
And I promise I will inform everyone here as to what I observed. 

Very best regards from Aubrey.
