Thanks Dave ! ;)
DeepSkyStacker will not be a problem, it will simply do the job as usual :

IMO, the simplest Stacking Tool
my BIG problem at Marseille is the Atmosphere's Stability
with your DA* 300mm on a Pentax Q, you'll see the Stars Blinking, Ok !
with a 1000mm you'll see the Stars Dancing...
( 1000mm on a Pentax Q = the same Reach as a Celestron C14 on an APS-C ! )
Many times, I've had to Trash ~ 50% of my 30 sec. subs ~
Here, the Sun Heats the Sea all the day long for more than 300 Days per Year,
at Night, usually the North Wind brings Cold Air over the Warm Sea !
The Precision / Sharpness of your Results depends on your Atmosphere's Stability...
- else it depends on your Determination to Trash every Blurred Sub ! :(
M-106 Galaxy : ~25 Million Light-Years from Q10 - apparent core size 2.5'x 6'
Magnitude minus Air- and Dust- and Light-Pollution worse than 10 ?
M-106 Galaxy : Q10 + SkyGlow Filter + Skywatcher 200/1000 = 88 x 30 seconds @ ISO 1600
Stacking = DeepSkyStacker 3.3
I highlighted 2 Stars close to the Galaxy :
- the Yellow one named USNOA2-1350-08095435 : Magnitude 17.3
- the Blue one named USNOA2-1350-08095450 : Magnitude 17.1
the distance in between is about ~8.5 arc second
Dumbbell gets More Pixels :
Messier 27 as seen from a Canon Eos 20d = 2.4 MPixel / cm²
-vs- shot by the Pentax Q10 = 44 MPixel / cm²
Both were shot at ISO 1600 :

Good Luck ! ;)

I haven't seen very many images from this lens, and I myself had largely ignored it until I purchased a K1.
This has now become one of my very favorite lens, one I had planned to exercise this past weekend for a planned portrait shoot that got rained out. It's got a special glow at 1.4, and I love the softness it delivers while maintaining detail. And that bokeh, like melting butter!
I'm pretty sure it will be a marvelous lens for portraiture, and bonus it works well with the Pentax 1.7TC for adding auto-focus capabilities. Examples follow. All the "85's" are from that combo and most wide open. The 4th one, butterfly bush flowers, is a 100% crop, as is the second image.
By the way this is the 8-blade version
EDIT: The last one is our puppy Bella. My wife loves every pic I take of her, so she makes a great excuse for a new lens purchase. :)
This is an old lens I've had for years. But imagine the pictures of her with an 85 1.4!
