Secretariat ..

After seeing this mosaic (http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/5054445/page/3/view/collapsed/sb/5/o/all/fpart/1) on CN, I went looking for all that curtain behind the horse. It seems I'll need a lot less than 600mm FL to get it in frame.

So I had about a dozen odd Ha shots from the FS-102 and mixed it with 4 each LRGB from the FS-60 that I shot in January and got an image out of it. I found a fair bit of colour noise showed up which is pretty normal when shooting RGB from the suburbs here and I've tried to smooth it out. Possibly a bit red too.

So L+Ha : R+Ha : G : B, 5 Hours total. FS-102 + FS-60.

Added image with more Blue.

Ripper image Robin. :)

Nice and sharp. Top left tilt giving stars egg shape. Ailnitak looks good.

Cheers Nettie.
Didn't notice that Paul.
It looks like a registration error in the red channel. Had to warp the fs-102 subs a bit to match.

This looks great Robin

The stars look lovely and you have Alnitak looking perfect :thumbsup:

It's looking a tad red-orange to me so it may benefit from some additional blue.

Very nice result mate :thumbsup:

Cheers Mike, It's good to be able to get something from what's basically test images :)

The problem Paul saw seems to be differing field curvatures between the scopes which effects the registration. I hadn't considered that at all.
I'll try a bit more blue, I did back it off initially as it tends to bloom on stars out of the FS-60.

Yes saw that but it was pretty minor really and Paul had already pointed it out.

Two great looking photos Robin.

Great composition and very sharp.

I really like the colours, especially the second one.

Thanks.

Ross.
