Thanks chaps there was a really great window of good seeing in the wind. Didn't last long though

It looked superb to the naked eye in the eyepiece. Sorta like the Hubble photos from a distance.

Could Dick Tracey have imagined that one day an ordinary member of the public could film the expanding remnants of a stellar eruption located some 7000 light years away, on their small hand held wireless telephone's.. camera through a..?..(well pretty big amateur telescope... ) and transmit it around the World..? Cool huh?

BTW, I downloaded video and tried to process it (pipp, AtoStakkert, registax) as it was a planetary image... but the results were not much better (obviously not enough information present in the movie).

That show great detail with good seeing. Shows the power of a super big scope.

True, I'm actually going to go bigger, considering pushing on up to a 40" f4. It'll take some time and effort but it's doable

Great catch. Terrific video. Beast of a scope too, not your average rig.

I just looked through that 40" last night at the ASV dark sky site.

It's the first time I've ever looked at an object through a telescope and thought 'Huh, it looks just like the picture' (Thor's Helmet, Ghost of Jupiter, Eta Carinae, Tarantula and others).

I wish I could afford that scale, but alas, no.

Oh man I can only dream of looking through one of these! If Barry upgrades to a 40”, I may have to move back to Perth & drive down to Rockingham to take a peek through it!!

Well I'm told a 40" f4 Plate glass Hubble Optic mirror is about $US 24500. So add secondary cost plus shipping and multiply by exchange rate plus GST there won't be any change out of $40k + in real money. Not doable in one hit but spread over a couple of years it's possible. I'll have to build the dob myself so it won't be SDM Quality but the mirrors gonna be the hump bit. So strategy is save money, pray for parity
