20 second M8....

....gotta love these fast Newts- the 20 second framing sub for M8 Nebula.

.....now to process the main stack!

careful mate, posts like this will put us slow frac owners right off you .

Can't wait for the stack.

Nice,

Just looked at your sig, is it the GSO 12' and are you reducing?

Here's the final stack 3x 300s @ ISO1600. Not as much data as I had hoped for (maybe add more subs later)

Just the job to whet my appetite

Hoping to do a smash and grab on this tonight (probably only in Ha though), as I have just a fleeting glimpse of this above the tree line in the distance.

Both great images.

Yes- GSO 12" F4 Newtonian and an ASA Keller 0.7x Reducer/Corrector.

Also this is the first session I tried guiding with the Lodestar x2 camera- which worked a dream.

Agree fast newts are the way to go but they need to be mechanically robust.

I found the Keller 0.73 reducer a nightmare to produce a flat field on my newt and endind up selling it due to frustration.

At F3.8 collimation was difficult and it showed up my scope mechanics or lack of then.

They do eat photons as youve shown.

Anyone else see a leering skull in the middle of that

I agree - working at F2.9 is not for the faint hearted. You need to be prepared to do some serious scope modifications (on the budget F4 scopes at least) and even then I'd recomend re-checking collimation/focus between subjects.

The key I've found is to find a decent laser collimator and you're 90% of the way there.

Still - all my Newts are also fast F4 instruments- even without a reducer they are not exactly slow!
