and your lights?

Image A: The Qld Astrofest imaging field. Not my setup.
Image B: Testing a new observing tent. There is a laptop with a white image on the screen. The laptop is in a box. The light is still to bright.
Image C: A simple solution a tarp over the tent. Also do not point the laptop screens towards the open tent door. Even with the tent covered I would still put a red filter over the screen.
These images were all at 30 seconds at 1600ISO.


The following show how bad a red led torch can be. The torch was a Celestron firecell which has 4 led lights in it.

Image D: For reference picture of my house from 20m away with no torch lights.
Image E: The torch unmodified, 15 seconds held at head height.
Image f: The torch covered in black tape with a 5mm x 5mm hole over 1 led. Still to bright.
Image G: The torch unmodified looking directly in to the camera.
Image H: The torch with a covered lens.

The images are 15seconds at 1600ISO.

Obviously what you do in your backyard is not a problem, but at astrocamps it is another issue. Do you really need a torch that can light up buildings, telescopes and eyes from 20m away?

I wont be using the Firecell torch anywhere near any observing fields.
