M57 with 300mmF12.5 Mak

Finally had a reasonably clear and steady night to shoot with the 12" Mak. Here is about 4 hours of H-alpha combined with one 20 minute Luminance. All taken at F12.5 with the STL11K at 1x1 binning.

This first shot shows the entire field, which shows the large field size that one gets with this camera in spite of the long focal ratio. M57 kinda looks lost and forlorn in this shot. The image is approximately 1/5th of the original size.

But, hold on to your hat because the mighty Mak can do both wide field and closeups in one shot. Stars overall measured around 1.8 arc sec FWHM.

(next couple of days I will add color to this if the skies hold up)

Breathtaking! That's all I can say, breathtaking!

Hello Roland,

this is, by far, the most detailed image of M57 I've seen in a long time!
Now I will hope for good weather in your area so that I can soon see a colr version.

Ciao

Rolando,

Holy ****! What a fantastic image! I was expecting no less from this baby, but seeing what it can do..... *drool* Congrats on yet another winning product!

Roland,
Great capture and process. I like both images - But I do like the wide field shot and I hope you add color to both images. What about a "medium" crop?
