We'd love you to take part in the June Imaging Challenge. Please post your deep-space images of NGC3132 in this thread. Discussions about the images can also be in this thread.
Please ensure the image obeys the image posting guidelines when you attach them.
While it would be nice if the image were taken in the month of June, it's not essential so feel free to post older images if you're unable to take some new ones.
For observation reports and sketches of the object, see the "Space & Astronomy Talk" forum.
Hi all,
The clouds cleared for about two hours on Saturday night so I thought I'd give this challenge object a go. It was the best skies I've seen here in a long time and managed to get some excellent resolution as a result.
Thanks Mike! I was amazed myself at the resolution in the raw images. If not for the June challenge I probably wouldn't have imaged this thinking it to be too small for my system. So thanks to you!
Looks like June is kicking off with a real blast guys. Top Stuff to both of you. It amazes me how the two different imaging systems can make such a difference in how the final image looks.

And how! This idea extends to every imaging system in the world. It's always amazed me how no two images of the same object appear identical, whether amateur or professional.
Great shot, Eddie, with that pixel scale you'd get a great shot of the Ghost of Jupiter too, you ahould try it before it gets too low in the west, wont need long exposures either due to its very high surface brightness.

f24 with 6" f6 Intes Mak-Newt. That's 3600mm with an ST10xe giving a field of 10 x 8 arcminutes, though this image was cropped. Pixel scale was 0.4 arcseconds and the seeing was the best I've seen so far this year.
Thats some serious Focal Ratio Eddie. I'm impressed.
Thanks! The Intes is well capable of it. If only my skies were regularly as good.

Each pixel in the image covers 0.4 arcseconds of sky, so that is theoretically the smallest resolvable point, but generally speaking most skies aren't good enough for sub-arcsecond resolution anyway.

You would have been using a good mount for that F-Ratio to. What mount were you using Ed?
I have a Losmandy G11 and the image was self-guided on-axis by the ST10. Accurate guiding is half the battle. The other half is having a mount capable of guiding accurately Losmandy introduced high-precision worms for their mounts a couple of years back and it made a huge difference to the ability of these mounts to track smoothly at long focal lengths.
