Re: what are you doing ?

Astrophotography update :-) I had been hoping to take some wide field shots of the constellation Orion, to provide a bit of context for an image of the Orion Nebula I have been working on. But the weather has not co-operated, so the first two pictures below have been lifted from Wikipedia - I hope t...

Re: 6550 SE Amplifier

They are your valves, so up to you. I manually turn heater supplies up then b+. Two outputs on the variac, all heaters first, then b+. I always assume a unexpected short term power outage could happen, so I either make sure that the startup control is automatic, or not needed. The chokes arent inst...

Sorry Nick :D
See star seems like a good package.
Looks like it even includes an OIII / hydrogen alpha filter. You will find this even allows imaging in light polluted skies or with a bright moon.

Re: what are you doing ?

Cheers guys. I have a plan for the next image but I need some clear nights!
If the weather doesn’t cooperate I will dig out some old data to re-process.

Re: what are you doing ?

cropped tighter.jpg Known as the Whirlpool Galaxy, this is actually a pair of galaxies interacting. I said a while ago that Andromeda was an easy target (basically it's big and bright). Well, this is a more difficult one (it's a long way away, 23.5 million lightyears, and therefore apparent size an...

Yep, the A7S is getting a bit long in the tooth, but it’s still one of the best for low noise, high ISO.

Re: what are you doing ?

Been having a tidy up on the computer and came across this photo. In 2016 we visited a part of France with pretty dark skies (Astrofarm in Confolens). This was a single 30 second shot of the Milky Way, ISO 3200, can't remember what lens but possibly a Rokinon 135mm. I've just given it a bit of a twe...
