Hi from Neil

Just touching base. I have returned home after 2 1/2 months in the US. National Parks road trip and stay with family in NY.

Glad to hear you may have found an alternate observation site.

I expect to return to my mirror grinding project soon.
I purchased a slightly damaged 8" mirror and have been re-grinding it.
Started with #220 grit (Silicon Carbide) to remove the existing alloy coating and reduce it to Focal Ratio 4.5 from a 6.7.
Progressed to #320 grit to make my target of 2.83 mm sagitta.

Had to leave the project at this stage for the US.
I suspect I may have to re-asses the quality of my plaster/tiles grinding tool to achieve full contact and an even sphere from centre to edge of the mirror.

All the best
Neil

Hi Neil,

Good to see you back. Hope you had a nice time in the US.

Speaking of this New Moon weekend... what is the score?

Any takers for Saturday night?

And where will we set up?

Looks like I am going up to Pony Club on Monday night.
http://www.iceinspace.com.au/forum/s...d.php?t=158177
Anyone care to join us.
Karena is keen to photograph the milky way - but I don't know much about that side of things.
Anyone with photography skills welcome to come along or post here to assist.

I believe her equipment entails a Canon DSLR and a basic photo tripod and a wide-angle lens.

If you have any advice, perhaps you can post to her thread?
F stops; film speed; exposure time, aperture? What else?

Hi Allan,

I have just sent you a PM.

Monday won't work for me, unfortunately. Tomorrow it is.

I aim to be at the PC around 4:30pm.

All are welcome to come on up.

AstroPanel suggests that temps will get as low as 3 degrees after midnight. Dress appropriately.

Hi all, please comment on this letter I drafted to the Glider Club ( Mangrove Mountain Soaring Club ).
I struggle with writing this sort of letter, but please comment and if OK I can send it away ASAP.

Rgds Geoffro.

Dear President / Secretary,
On behalf of a Group of Individuals who share the same passion for the Night Sky, I wish to express our desire to be able use your Club’s Airfiled for the purpose of Stargazing .

I am actually part of an informal group of Amateur Astronomers and like-minded individuals, who gather together once or twice a month to observe the night sky with our Telescopes and associated equipment.
Sometimes we may gather together outside the normal “ New Moon” Monthly get-togethers, for a special Astronomical event such as a Lunar Eclipse or Meteor Shower etc. However, we usually get together just a couple of times a Month.
At present, we are using another venue, which has an increasing amount of light pollution that affects our ability to both observe and enjoy the dark skies available at Mangrove Mountain.

At this point, I personally would also like to convey our Thanks to your Club, for allowing us to visit your Airfield a month or two ago, and try the site at night for our common purpose.
We found the Airfield to be a most suitable area for our Stargazing activities, with a minimal amount of Stray light that would detract from our enjoyment.

We as a group, also note that you may have certain Rules for using the Airfiled, and we are most happy to abide by your rules or restrictions, to ensure your Airfield remains safe for your activities, as well as our intended activities at night.
We would also be most happy to show your members the Night Sky Treasures that are within the reach of our Telescopes and equipment.

I will await your reply, and convey this reply to the other people in our Group.

Thank you in advance for your consideration in this matter.

As an informal and friendly conversation starter, I'd be happy to go with that.
But I would try to avoid a commitment.

Great stuff, Geoff! It really is a great location at the southern end of the air strip. Those that went to the northern end for a look, what was it like in comparison? I would think it would be closer to Bloodtree Road, and vehicle lights.

Is anyone interested in heading up to the pony club tomorrow (Friday)? Saturday is out for me, and I would like to get up there if I can.

Maybe I can make it.
Can I bring my drones and lasers?
They won't ruin your dark adaptation... promise.

Still looking at tonight.

Aiming to get to the gate around 4:30pm.

Looks like it will get as low as about 3 degrees, so an extra pair of socks may be in order...
