The Ring Nebula

Another well-known object to try the new Atik 460 OSC out on! The Ring Nebula, M57, in the constellation of Lyra was pretty much right overhead when this was taken. It’s comprised of 23 x 5 min exposures through the MN190. 14th magnitude spiral galaxy IC1296 is faintly visible below and to the right of the nebula.

A Narrowband Ring

The Ring Nebula in Lyra, M57, is one of the most well known deep sky objects. With narrowband filters, response to H-alpha and OIII is strong, but there’s much less emission at the SII line. This image was put together using 30 x 1 min through each filter. Initially, all 90 frames were aligned and stacked; this was subsequently used for the red channel. H-alpha and OIII were were stacked separately and used for the green and blue channels respectively. The image was captured using an Atik 314L+ through a Skywatcher MN190.

M57, The Ring Nebula

The Ring Nebula is one of the best known deep-sky objects, but that didn’t stop me trying to image it last night! This is composed of 3 x 10min frames each of Ha, OIII and SII, taken on the LX200R without focal reducer, and was put together using the Hubble palette of R=SII, G=Ha, B=OIII.

The Ring Nebula

As we had the first clear night for a while tonight, I thought I’d spend some time before the moon came up on the Ring Nebula, M57. It’s not something I’ve really had a go at before, and I’m reasonably pleased with how it came out. This is a stack 0f 25 x 200 second exposures at ISO800 through the LX200R with a Meade f/6.3 focal reducer fitted, guided with PhD.

Next time I’ll try without the FR to see if I can get a better image scale.
