Thank you Milton.
Nice place -31° or -41° ...WOW .
The only advantage is about not having dew...isn't it? LOL.
Very hard to do astronomy with that temperatures!
I watched a vintage documentary (40 years ago) about Calgary and the Stampede so i was thinking of you.
Was it true that the most famous hotel prohibited to take the horse into the room? (i mean 40 years ago!)
About the pitch: yes it is very strange. I'm trying to simulate the sound that i hear with voices at telephone.
Do you know the HAM radio SSB mode? (USB-LSB).
Tuning the BFO produced similar double metallic effect on the voice because currently my hearing is "not linear" meaning that the intervals are not the same as the original.
Honestly it is pretty interesting to analyze (even if i hope to recover even this effect!)
NICE MOON TONIGHT (crying)
Tmorrow morning i should go back home
Goodnight...

Hi Alberto;
Sorry to hear about your hearing issues, and glad to learn that the treatments have rectified the worst of it and that your going home soon :)
It must be very very strange to have that irregular pitch shift happen.
Hope you get that last bit pitch shift straightened out, so that music doesn't sound to weird.
PS:
It was clear here last night, but at -26°C (wind chill was -31°C) I decided it simply wasn't worth it . To the east of me, parents were recording wind chill temperatures of -41°C last night, and "Spring" is 10 days away. So where is this "global warming" I keep hearing about :)
TTYL..

Hi group,
i'm reading and envying your discussions from my hospital room LOL.
Nothing really severe but since 7 days i'm here because of a sudden hearing loss at the left hear.
Luckily I'm i'm responding well to the therapies and and every night i watch at the Moon feeling a incredible wish to be at home with my scope.
I couldn't do any imaging of the Moon since December 2008.
On January and February the weather was always cloudy but some days ago, thanks to the good forecast, i planned a nice "March Observing Campaign" inviting a friend of mine with his young son to test the scope on the moon and saturn on Friday March 6.
Usually I never do plans but this time i dared ...
Result: on March 6 i was recovered while I never was recovered in hospital before.
LESSON #1 : I will manage to skip further plannings!
Hopefully tomorrow i''l be back home but the moon will be too low on the horizon (i have a disturbing roof hiding the sky below 35°).
Cheers to all and have great imaging sessions...
Alberto
------------ ------
For who loves technical details about my hearing loss experience.
During this experience i discovered (again) that our body/brain can do everything.
I always thought that hearing loss was related to the AMPLITUDE of the audio waves but now i discovered that even the FREQUENCY is an arbitrary perception of our brain.
During my worse phase my left ear could hear a frequency of 580Hz while the real sound emission was 440 Hz.
The frequency shift was not linear meaning that even a frequency of 300 hz was listened similar to 580 Hz.
Even a frequency of 500 Hz was listened similar to 580Hz.
A part of the lower spectrum was flattened and mixed .
As a result a spoken voice was listened like a distorted HAM radio voice or ROBOT voice.
Pretty interesting and absolutely unexpected phenomenon.
Nowadays i hear the 320 Hz similar to 330 Hz.
That's not good for music hearing yet, but it's a huge improvement!
