Hi All
This was taken over three nights and is of NGC281. It was taken with
Takahashi FSQ106ED at f5
Paramount ME
Starlight Xpress SXVF H9
autoguided by Lodestar and OAG
12x30 minutes Ha, 7x30 minutes OIII and 12x30 minutes SII using 5nm filters
The OIII and 3 of the SII sub frames were shot last night under a full moon, 9 of the SII sub frames were shot under very poor seeing and transparency conditions thanks to some very high thin cloud and half of the sub frames from that evening had to be rejected so I am quite pleased with the overall result.
Gradient removal was used but no sharpening, this was mainly levels, curves, contrast and a minor shadows/highlighs adjustment and selective colour
The full size high resolution version can be found at my pbase site at the following link

The Ha version can be seen in the image gallery of my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/)

along with a previous attempt at this object with the HST palette 2 years ago

Thanks for looking
Best wishes
Gordon

Looks the part, you have it all down pat it seems, the stars look nice I critiqued on the last image, but nothing to fault with these.
Good to see you are still getting some clear skies....... Soon to end as winter comes upon you no doubt,
We are still moaning about the cloudy skies here in southern Victoria, I think we've had 2 clear nights in 3 months, so it's hard to keep up the enthusiasm.
Checked out your website, very well put together,the moochy dogs are great too.

Very nice as usual Gordon. I have some real problems putting together a NB image in HST and getting the yellow areas correct. Perhaps I need more data.

Well done.

A nice result there Gordon. Very good.

How come you're not using your BRC for this type of shot?

Greg.

Hi Greg
Thanks for the comments, the BRC is currently waiting for a mirror clean thanks to some condensation that got on it and drying and leaving it dirty, as I don't drive I'm waiting for the shop owner to find a window when he can come and pick it up, consequently most of my shots are widefield except for the occasional use of the H9
Best wishes
Gordon
