NGC 891 - 8" F/4 | Emberger Alm ITT 2012

[Betelgeuze]

Hello people,

I visited the ITT 2012 at Emberger Alm and met some really nice astronomers there. In addition to that i switched to Off-Axis Guiding, which improved my Guiding perfomance dramatically.

One of the cables of my MGEN Autoguider broke, so I was not able to use the Dithering-function.

Here you go, I hope you like it anyway:

Very nice image indeed!

[fwm891]

Superb image - 891 is a personal favourit

[Dipper]

Amazing. There's a whole bunch of tiny galaxies all over the image as well.

[ultranova]

A very impressive deep smooth 891 with at least 25 background galaxies.

Unless i missed it some where, What camera was this taken with and what software did you use to process it

Great shot Paul

[MartinB]

Lovely clean image. Some detail in the faint fuzzies as well. Nicely processed

[swag72]

A very nice image there, looks great just hanging in the wider context.

Very nice image

Hey Simon,

Great to "see you" around here mate

So, I see your meeting went well, what a great image, superbly processed!

It's good to see that you're using 200 ISO, what do you say about it? Been a fan of lower ISO values and longer subs since long ago, you end up with better dynamic range and lower noise, better star colors (they dont blow up as much), and a cleaner image at the end without so much "hammering" in post processing, next imaging run I'll try 100 ISO with 20 or even 30 min. subs with my cooled 350D, I've just assembled a more powerfull peltier unit on it

The down side on doing very long subs is that you have to be perfectly polar aligned or else field rotation starts creeping in your subs...:/

About off axis guiding, are you using those new TS low profile oag'S?

Greets,

Luís

That's a lovely image of one of my favourite objects

Thats an incredible image, I lost count of all the faint background galaxies, very nicely processed.

[Betelgeuze]

Thanks for all of your compliments! I'm very pleased

Hello Luis, nice to hear from you here!

Yes, I will definitely stick to a lower ISO, but I probably not go further down. Yes, I'm using the OAG9 of Teleskop-Service. Good luck with your Peltiercooling.

Camera is an unmodified 550D - processed with PixInsight

I'm looking forward to seeing more nice images from your location. This is an excellent result with a DSLR, keep up the good work.

[fredster]

Stunning image, such a lovely widefield, stunning stars and the galaxy itself is amazing.

[davew]

Wunderbar Simon,

That looks about as good as a DSLR image gets.

Very nice, detailed and clean.

Dave.

[SJJ]

Great image, love all of the stuff going on in the background as well.

[RobH]

Cracking result and fine processing....891 is nice and bright but you've controlled the stars very well.

Cheers

Rob
