I received a phone call from my very close friend Bert today, all excitedly he said he is sending me an email of his latest pic. Now, to set the scene: Bert is an extremely well respected Astrophotographer. Not so much by the amateur Astro world but by Professional Astronomers and Astrophysicists who study Bert photos for scientific research. Bert has the incredible ability to go deeper than any other Astrophotographer, revealing previously unseen detail even though he only has a viewing hole of about 20 degrees between trees he is not allowed to cut down, in his heavily light-polluted suburb in Melbourne Australia. The photograph he sent me today is a mono shot of the Helix Nebula that has gone deeper than the Hubble and Spitzer Space Telescopes!!!! In his photo another outer shell was discovered further out than the outer shells previously discovered by the Spitzer Space Telescope.

I drove down to Melbourne yesterday to visit Bert and learning how he does his whole procedure. He is keen on relocating all his gear up here to our site and control it all remotely from his house 173 kilometres away. Imagine how much DEEEEEEP data he will collect from our dark sky here if this is what he achieves in light pollution!

Not quite up to Bert's standard ,but ok for l'il ol' me. Helix 30s x 20, zwo 290 ,Rasa 8 . Certainly a lot longer exposure than what I am used to. The first is from sharpcap and the second is with a little stretch on astrotoaster
cheers Paul

Of course, with 30-second exposures we will never achieve this ......
But every night we can see many more objects than him.

Carlos, I might start doing some 1 minute exposures and see how I go.I do not want to launch into guiding so 1 minute exposures will be my absolute limit Astrophotographers dont regard seeing multiple objects in one night as an advantage. "Why see multiple objects when you can do 1 really good one" is the way they think. I dont see it that way and I am very glad we have our own forum. We have a a very good Astrophotography forum in Australia but they dont seem to have much time for Video Astronomy. cheers Paul

Here's Bert's Observatory, among the trees. The roof splits in the middle and opens out each side as far as the trees will let each half open (which isn't very far).

I think that camera manufacturers are not very interested in the cheap cameras that we serve and their main market is the expensive cameras (and very expensive material) for astrophotography

If he had said I had to control it I would have said no instantly
