A nice conjunction to end the astronomical year.

I assumed it was there above the clouds.

Thanks for the photo so I could actually "see" it.

Geostationary Satellites

Posted By Alan French

Hi All,

I ahd an unusual observation a couple of nights ago. I was checking out M42 for fun with my 18" dob, when I noticed 3 objects moving across the field. I quickly realised that these were goestationary satellites as I have often had images of this region ruined by these things!

What really struck me though were 2 things. Firstly the 3 satellites were in a nice straight row.

The second was how the brain worked. I stopped moving the telescope to keep them in view, but even though I KNEW that it was M42 that was moving across the field, the brain kept trying to tell me to move the telescope to keep the SATELLITES in view!!!! 8O

It was fun watching. The were about 9th - 10th magnitude.

Anyong else seen this?

Regards,

Maurice

Yes, we saw three at Stellafane last year. Turn off the drive and watch the stars move by - what fun!

What's it worth? Unitron Model 134 w/ accessories

Posted By Alan French

You might have more luck with the Classic/Antique/Vintage forum.

It is very collectable, but I don't know what a fair price would be. I suggest making an offer you are comfortable with and seeing what happens.

Moon Venus in Daylight

Posted By Alan French

Yes, it was very easy. I've been watching them off and on most of the day, and am looking forward to Venus, the Moon, and Jupiter after sunset.

400mm F9.5 Binocular Reflector Telescope For Sale

Posted By Alan French

That could be the poster child for a White Elephant. You'd need a launch vehicle to get it above our atmosphere.

Hi Alan,
I have two Brandons 4" F/15 lenses and one Witherspoon 6" F/17 lens.

Cool. How do they perform? The 6" f/17 sounds marvelous.
