Crescent in Ha.

Hi all,

Seems like forever since I have imaged anything! I decided to go to a larger,longer scope back in March. Took a bit longer to get everything together than I expected and then the Spring weather here has not been kind for astroimaging.

Last night I finally had a chance to use this new scope as the clouds parted later in the night,of course now we have a nice bright Moon so first light for the new scope is a fairly short Ha image of the crescent nebula.

This is just 25x300s through a 6nm Ha filter with a Meade 12" ACF tube at F6.8 and my ST10xme binned 1x1. 1200 gto guided with an efinder and remote guide head. Image reduced to 60%

It needs more and longer exposures and it seems my collimation is not as good as I thought it was wink but I see some potential for some good higher resolution images with this combo once everything is dialed in.

It was good to image again!

Thanks for taking a look,your comment always welcomed.

Jason

Very nice work, especially for such a long focal length. The setup looks like it will provide a lot of detail at a nice image scale.
Cheers,
Tyler

I think you're right about the collimation, Jason, but the ST-10 is nicely matched to your scope, right around .7 arcsec/pixel.
