M16 Eagle Nebula, DSLR

Recommended Posts

Having recently moved to new pastures/skies, and finally unpacked most of our stuff, I thought I'd give M16 a go before it disappears completely.

 

I now have a much wider view of the sky -  but there is a big tree to the north and another to the south, so polar alignment is a bit tricky, and objects low to the south horizon get interuppted for an hour as they pass the meridian. I could get around this by pitching the other side of the south tree, but this needs a very long extension, and a bigger hike with the kit - for the future maybe.

 

Had a real nightmare with the GoTo - it seem to get it horribly wrong when low to the horizon, and consequently only got 6 decent 8 minute subs. Also the guiding was horrible - something odd has happened since re-assembly. Or maybe that's just because its lower, but the Dec and RA RMS errors were 0.5 ish which is double the usual figure.

 

I spent a good while getting it centred as I still dont have a coma corrector, but discover that theres a lot of nebulosiy lower down so would have been better set a bit different. Had another go the following night but although I got more subs, the quality was worse - low haze I guess. 

 

 

And, it seems the price you pay for a nice dark sky is lousy broadband!! Three weeks to get hooked up to a slow, expensive service.... Still got another 10 days to wait. Grrr. So, this is a lowres image - on my screen it looks way better! (kidding) I reckon its not bad but would have been better for more subs and better guiding.

 

Enough with the excuses...!

 

6 lights at 8 mins ISO800, library dark/flat/bias, DSS and Paint.net.

 

 

What do you think?

Excellent, what set up did you use?

Thanks! Set-up pretty much as per signature - 200PDS on HEQ5, Orion 80 guidescope with starshoot guide cam.

Despite of your difficulties the capture is very nice. Many informations from the nebulosity. 

Muito obrigado!

Nice picture.

Rural and internet (and even mobile signal) are mutually exclusive it seems!

BT say I should be grateful for my crackly land-line in Powys........
