wow, that is an excellent image Richard. regards Ray

That looks amazing.
How long we're the subs and how did you control noise with the 1000d?
Isn't the vc200 an f4?
Nice work
Cheers

That's excellent. The contrast and colours are gorgeous. :thumbsup:

Fantastic image, Richard! The colours have a real natural hue to them and you've done very well to bring out the rich golden colours of the star clouds. A tidy image indeed. Well done.

Thanks for the lovely comments everyone.

This was 106 x 4min subs at ISO1600. Captured using BackyardEOS and processed with PixInsight. Each sub was dithered.

There was very minor noise reduction applied using the TGVDenoise process in PixInsight, however noise is basically kept under control by the use of dithered subs (and lots of them).

The VC200L is a f9 scope, however I am using the f6.4 reducer

That is good Richard!:thumbsup:
Imaged 6559 last year, wasn't as good as yours.
I'll have to revisit, and get more data as you keep raising the bar for dslr imaging.

Cheers,

Justin.

Very nice, Richard! That's a cracker of an image.

Lovely result Richard, that golden star in the lower right sets the field off beautifully. Might pay to have a squizz with the green turned down just a tad..? But a great shot :thumbsup:

Magic stuff Richard, as usual. The DSLR Astroimaging King :)

stunning shot beautiful colour

[Logieberra]

Richard, churning them out! Real nice.

How are you doing your darks? Canon auto-dark, on the night or from a dslr darks bank using comparable temps to the night taken?

[rmuhlack]

the latter

Thanks for the nice comments everyone :)



A reduced green version is attached. The original actually looks okay to me on my monitor; this one looks fine also, i guess its probably down to monitor settings.

Thanks Logan. I'm actually in the process of setting up a second wide-field rig with its own mount that I can operate in parallel to the main scope (my VC200L). So looking forward to doubling the image output on those nights of clear weather and good seeing !!

Thinking along the same lines Richard... hence acquiring the W.O Megrez 72 :)

Cool 106 subs. Well done on capturing that much data. Nice colour in the latest version.

Excellent photo Richard.

Great composition and I love the detail and colour.
