Centaurs A from Brisvegas

[Garbz]

I recently setup a little hut (hardly worthy of the name "observatory") so I can finally dedicate some real time to a few targets. No more 2 hours a night eaten by setup / packup.

Took this NGC5128 from under the glow of Brisbane. I'm not sure how long it is because it seems Pixinsight doesn't record the total integrated duration anywhere, but I think there's between 8-9 hours of data based on the number of subs and rejections (of which there are a lot and as a result my mount is now in pieces).

Certainly am far happier with than than any one of my previous shots of it.

Taken on a C8 with a QHY10.

looks promising ;)

you hyper-tuning the eq6 hey :P

[cometcatcher]

That's a very nice shot. Looks deep. :)

[Rod771]

Yeah that's good Chris! Nice detail :thumbsup:

[Garbz]

Thanks guys,



Not so much hypertuning rather decrapifying. I did find the RA worm was incredibly tight and the lock nut on the Dec axis was so tight I needed an oil filter wrench to get it off. Maybe that all had something to do with my crap guiding.

Good image Chris!:thumbsup:

Nice colour and detail.

Cheers,

You did well to get a decent galaxy image from Brisbane skies, Chris!

[Garbz]

Thanks Rick. It's depressing to think how nice this would turn out if it wasn't a Brisbane photo.

What they said.

[PeterEde]

Looks nice
I'm itching for a goto upgrade

[Screwdriverone]

That is a VERY tasty suburban Centaurus A shot Chris!

Really well done, the details and faint colour in the filaments on the dark band have come out beautifully.

Top work :D

Cheers

Chris

[Garbz]

Thanks, now I just need a sharper scope and a vacuum to put it in to improve the seeing :)

[strongmanmike]

I agree with Chris, an excellent suburban Cen A :thumbsup:

Hey Chris,

just read your comment about your "crap guiding"...

I have to ask this question...
Is your guide camera and imaging scope pointing at the same thing? If not you will get drift over a long enough exposure.

I took a 30 minute exposure of M16 a couple of weeks ago and found the stars were tracing an arc. Because of the dodgy webcam I am using as a guidecam, there are no stars bright enough near the Eagle to guide with, so I was forced to shift the guidecam about 15 degrees to the left to find a suitable star.

So, I now point the main scope and the guidescope at exactly the same point. Not wanting to brag but I am now able to pull 60 minute subs with only slight elongation. And that is probably due to PE on my HEQ5 Pro. PHD settings may be helping, but I am certain that having both scopes exactly aligned really is key.

I will upload the 60 minute sub soon...

But your picture looks excellent!

Hope this helps.
