Nice sketch. I am just wondering how you managed to sketch that holding the binos with your hands! :shock:

Affraid,

Its just a case of look, put bins down, sketch, then look again, and so on.
Pretty easy once you've done it dozens of times.

Being a bino-only observer that's how I do all my sketches ... must help keep the memory sharp! :)

Eddie,
What about asking the Captain to update the ship's binoculars to include a 25 x 150 Fujinon on a mount. Maybe a gimbal mount.
Surely a necessity for a modern ship.

David,

Its bad enough getting the company to order food stores. :roll:
I'm always asked to take a scope.

3 major factors stop this.......

a) Size of my scopes

b) Will we get any time in port.

c) Will I have to fly home from anywhere.

I'm going to buy a Green Laser Pointer before I go back. Easier to show objects.

Cheers Ed

Dear Eddie,
You need one of Horace Dall's folding pocketable Dall Kirkhams.
They were really tiny and he took them I think on his bicycle trips say across Iceland and Lapland.

There are tiny Maksutovs such as I think the Russian Astele about 65 or 70mm.
There may be high class Skywatcher smaller than 90mm.

I use selected 500mm f/8 mirror lenses and some can easily take 100x with a monocular adaptor and 2x teleconverter.

I think you could find a good scope weighing around 1kg.

I suppose food might be a better option.
It would be difficult to get nourishment from eating a giant binocular.

However, every ship should have a small ships scope.

Dear Eddie,
There was an 80T Skymax tube and optics but I don't know if they are current.
The 25 to 75x x 70 Maksutov spotter weighs 1.03 kg.Acuter or skywatcher about £69.
The performance is not great.

House of Optics may have the
60mm Astele Maksutov 1.1 kg 300mm long ??
70mm Astele 1.5 kg 238mm long ??
These may be sturdy scopes capable of serious work.

I have a Mirador tiny Mak about 70mm which is superb. I think 40x to 120x zoom and other supplied 1.25 inch eyepiece.
But I have never seen another.
It may have been a reps. sample.

So there are tiny capable scopes that would easily go as hand luggage.

The only problem is the photo tripod needed, but they could be used on a small table tripod if a suitable sturdy wall was used.

If you use and take say a Nikon camera with a telephoto or zoom, the lens may be good enough to take a Nikon fit monocular adaptor, say Vivitar TLA 1 or clone.
It might even work with a 2 x teleconverter.

The old 500mm f/8 Nikon mirror lens certainly makes a capable 50x scope with a monocular converter and easily handles 100x with a 2x teleconverter.
Because these lenses have little false colour they work well as scopes.

So I think that you could definitely use a scope under 2 kgs on your trips if there was a photo tripod on board. These could easily go as air hand luggage as well.
There are also spotting scopes, some of which take 1.25 inch eyepieces also giving higher powers. But these are a bit longer than the Mak scopes or mirror lenses.

My day time hobby is twitching.
I'm going to purchase a Celestron Ultima 80mm. Gives 20x-60x. That would do nicely I suppose.

Dear Eddie,
Get the 5mm eyepiece also if the Celestron do it.
The Skywatcher Acuter has the HM5. This may also fit the Celestron.
There are two versions the Acuter the older non waterproof and the newer waterproof versions.
I don't know if the Celestron Ultima is an ED version.

I only have the Acuter 80mm old standard spotter with 20x to 60x and 95x HM5.

Regards, David

There is also a newer Skywatcher or Acuter that takes 1.25 inch eyepieces and has I think a dual speed focusser. Maybe nonED and ED versions?

Hi Guys,

This sketch was completed in pencil on white paper. This was then scanned and inverted using CS4 (photoshop).

Can be done via a digital sketch using Paintshop.
Create a black disc, using the Fill in paint bucket.
Then select the pencil icon, pick the size of the dot you require and click away. Would be a lot more precise of a dot.

All depends on what you want ......
