NGC 6744 with ST10XME

Terry B · #1 22-09-2009, 09:27 PM

Dear All
I bought this camera recently and so far have only been using it for photometry. Just to see that I could take a pretty pic with it I changed the filters from photometry ones to LRGB filters and took a short series of NGC 6744 in Pavo.
The images are taken through my VC200L at f6.4.
I binned the images 2x2 as unbinned it was seriously oversampling on the night due to pretty crappy seeing. (~4arcsec)
RGB were 5 x 5 mins.
Lum was 5 x 10 mins.
Processed in Iris.
My processing is pretty crappy as spending lots of time fiddling infront of the screen really doesn't interest me.
Even so I like the image of a nice face on spiral.
The first light of a pretty pic with my camera.

Yeh, nice Job Tezza

It's NGC 6744 though

Typo. Now fixed.

Top job on a very tough target... the ST10XME has what it takes to pull this faint little bugger out though... You must be loving the new camera over the old ST9E you had.. I know when I got my ST10 after using the ST9 for a few months, I was blown away by both its sensitivity, and having a nice, big image to play with rather than the 512x512px..

Good going.

Pretty neat Terry. Nice and smooth.

Thanks all

I am liking the new camera thanks.
Interesting it's sensitivity is about the same as the ST9E because of the difference in pixel size. Unbinned ST9 images saturate with almost the exact same exposure as a binned 2x2 ST10 exposure. The pixel size difference is the reason. 20um for the ST9 vs 13.4um for the binned ST10.
The big difference is the field size. I can now image with a focal reducer giving me a field of 26 x 40 arcmins rather than 19 arcmin square and still be a bit oversampled.
From a photometry perspective this gives me many more comparison stars to utilise.

Congrats on the new camera Terry. The ST10 is a workhorse. Excellent sensitivity, well suited to tackle killer narrowband images if that's your thing or as you say, accurate photometry measurements. Looking forward to seeing more.

Nice image Terry and congrats on the new camera.
The ST10 has always caught my attention.

Well done.

Glad to see that the camera is working out for you Terry.

Not a bad pic of a faint little galaxy there.

Cheers
