Rosette Nebula 28 December 2014

Kersh

Here is my first effort at the Rosette Nebula in Monoceros.

Its 49 subs at 2 minutes each, at iso800, so 98 minutes in total.

I put in a little effort with this one. Got everything setup by 10pm, got polar alignment fairly good with the Skywatcher HEQ5, I then did a 2 star alignment, with the 2nd star being Aldebaran, so I used it, and the fainter stars around it to get focus done with camera attached.
Swung around to the Rosette Nebula then,and thankfully,it was bang on where you see it in the image. Thank god for accurate mounts

Gear used was a Canon 1000D (astro-modified), attached to a Skywatcher 80ED-DS-Pro scope, mounted on a Skywatcher HEQ5 Pro mount.
Camera control was via APT, which is a free program, and means I can control the camera from the kitchen, once its all set up.






Stacked in Deep Sky Stacker, and processed in Photoshop (quickly!)

Beautiful...

What do you mean by "astro modified"?

Great one Kersh!

Generally its removing the IR Cut Filter to get infrared data and also copper cooling in some instance

As Zeroy said, its just usually removal of one of the filters.

Here is a link to the crowd that do either modifications to your own camera if you send it to them, or you can be already modified ones off them.

Here is the exact same data, re-processed by someone who knows photoshop post processing better than me!

Its all the same data, no trickery, just various tweaks are used to drag it out.





Many thanks to Dave Connolly Photography for looking at the data

That's a great image with only 2 min subs. Was it taken from a dark sky site? Strangely, I'd prefer the original image, way more natural looking.

It was taken from Julianstown. The horizon just below Orion is partially lit by the M1 Motorway, but all in all, its not a bad site.

I think I prefer the subtle nature of the original, though that was Dave's first re-process.

He has done another since that is a bit less "pushed".

Those Skywatcher 80ED's are deadly little scopes for the astrophotography!

Have you had much done over last while?

They are great little scopes alright. No Stephen I haven't done anything since 2013 but will definitely get out this year. Lost interest for awhile but started setting up again recently just for some moon shots and the bug is back☺

That's fantastic stuff Kersh! Really impressive. I haven't had the scope out all year due to time constraints. Might have to sell up, still those pics are inspiring.
