Managed to get out imaging the night sky last night. This image is about 3.5 hours of exposure time with 43 x 5 minute individual exposures stacked together to bring out the signal to noise and show you what is out there. This is the Pelican Nebula and Cygnus Wall located near the stars Deneb and Sadr.

Thanks - I use a Canon 400mm Canon lens with a dedicated ZWO 1600MM camera and NEQ6 tracker.

That's a bit above my level yet, just starting to get my head around it; furthest I've got so far is a 200mm on a home brew mount. It's a hell of a learning curve, but slowly muddling through it.

Wow, some detail there. Do you have it in colour?

Hi there, just gathered some more data last night using an Oxygen 3 filter that has allowed me to combine to the initial image. The Ha data (Above) is added to the Red channel and then the OIII data is added to the Green and Blue channels giving it colour (False).

Do you have any links to resources on false colouring? Whilst I'm not on that stage I've been having a look at things and there's a certain few websites which seem to be a bit (even to my limited experience) dubious in what they are saying.

Superb photo. Even if the colour is false, it adds to the photo mystic (IMHO)..:)

Not really no, but there has been a lot in the media years ago that Hubble photos are not real and fake. It all comes from them using the term 'False Colour' I think. All they mean is they have added colour to the data they have captured (in mono as more sensitive) to show what it is...very similar to processing a normal photo, but not adding anything, just manipulating it. Another edit showing the same data but just different colouring

Thanks for that, I'll got through and have a bit of a session when I get chance to sit down with some data in front of me; but not had chance for that this week as work has been constant (but on the upside, it's plenty of overtime to stick towards a mount and it's been constantly raining).
