The nebula disk has an angular size of 1.5 × 1 arcminutes, making it too small to be resolved with 10×50 binoculars. It is best observed using a telescope with an aperture of at least 20 cm (8 in), but even a 7.5 cm (3 in) telescope will reveal its elliptical ring shape. The interior hole can be resolved by a 10 cm (4 in) instrument at a magnification of 100×. Larger instruments will show a few darker zones on the eastern and western edges of the ring, and some faint nebulosity inside the disk. The central star, at magnitude 14.8, is difficult to spot.(Wikipedia)

This picture was taken wit my 130 mm at 12 shots x 25sec.= 300 secs total exposure.

Nice capture of M57! Looks like perhaps a bit more fine tuning of the focusing could pull out more detail and reduce the slightly bloated stars. It could also be the your mount had some tracking issues causing some drifting therefore loss of the fine details including the central star in M57.

Yes, i'm learning slowly how the camera and the telescope/mount works.

If I start stacking before the image completely stops moving the results are stars moved.

But I am very pleased with these initial results and my very simple telescope and mount. I never expected to see what I'm seeing now with these simple media.
