Too dark for my Q ISO 1600 required, not worth shooting at that!

Took some shots with the K5II instead, will just link instead of posting, as they are not AstroQ shots

I was traveling last week and only happened to notice the conjunction of Venus and Jupiter by looking out the window one morning before dawn. I didn't really have the right lens with me so settled for a Q/300 shot of a very "old" moon:

Cristmas soon : a Pentax Q(10) for a Celestron C14 ?

QuoteOriginally posted by baro-nite Quote
Time to specialize a bit from the "Reach" thread.
... +1, and the "Rich" thread too !

Pentax Q(10) are good for Deep-Sky-Astrophotography

if you multiply their Low-Light DxoMark by 30 in case of the Pentax Q(10)
you'll find they are very good cameras in Low-Light w/ Long FL
( 30 = 5,6 the Pixel-Field covered by a tiny target )

Pentax Q(10) would be Leader in DxoMark ISO Low-Light Ranking if it had a FF CMos...
... just under ISO 6ooo - not counting the "Print-Mode-effect" due to 366 MPix !

in other words, you can mount them on an inexpensive Newton,
you need a $7000 C14 to get the same Reach w/ APSc
+ the PQ10 Kit is too inexpensive this summer
I just bought one for €170 in August !

Cristmas is coming soon : a Pentax Q(10) for 3% the price of a Celestron C14 ?

M27 Dumbell Nebula : 1350 Light-years from Earth - apparent size : 8′ 5′.6 !
M27 Dumbell = Pentax Q10 + SkyGlow Filter + SkyWatcher 200/1000 = 50 x 30 seconds @ ISO 1600 :
stacking : DeepSkyStacker 3.2 - finish : Elements 3.0





Shot at sea level in a big city = lots of light-pollution and turbulence !

enjoy !

thank you Baro-nite !

and congratulations to Kendigitize...
for those lovely assortments of soft round Moons !

.

I found my M27 somewhat flat with opaque artificial colors...

I re-built it another way from 56 DNGs = transparencies and volumes

how about a strawberry Red skin around a transparent avocado Green flesh ?

+ plenty of Gold stars shining from inside !

... did I succeeded ?


M27 Dumbell Nebula : 1350 Light-years from Earth - apparent size : 8' 5'.6 !
M27 Dumbell = Pentax Q10 + SkyGlow Filter + SkyWatcher 200/1000 = 56 x 30 seconds @ ISO 1600 :
stacking : DeepSkyStacker 3.2 - finish : Elements 3.0





Shot at sea level in a big city : sorry for light-pollution & turbulence

hope you enjoy it !

for comparison with APSc Big-Sensor Cameras :
- a crop of one from my Eos 20d in 2010 = Exactly the Same Exposure Time :
http://en.astronomike.net/deep-sky/nebulae/171592.html
- and what I got in 2012 with my K-5 + a little More Exposure :
http://en.astronomike.net/deep-sky/nebulae/739277.html
... + K-5 on a 254/1200 Skywatcher

that's what happens if M27 only illuminates a few hundred of pixels in the center of a Big CMos !

plus CMos sensors from Pentax Q / Q10 are Very Sensitive :
- GQE = Green Efficiency of the Eos 20d is ~25%
- Green Efficiency of the PK-5 is ~45%
- GQE of the Q10 is ~75%

.
and now... Ladies, Gentlemen and Moon maids...
drum rolls...
... cymbals !

M27 Dumbbell from Pentax Q10... in Blue and Red... with much more stars all around !

being able to discard Green layer... to play with Blue, Purple and Red...
proves that this small Pentax Q10 gets a very good SNR...
even from harsh atmospheric conditions !
~same DNGs for the 3 pics.

about the ~same colors~ with my Eos 20d :

but much much less details

I wonder how well the Q would work with my 1000mm refractor?
Anyone ever try the Q on very long glass?

Taken with k20@1000mm prime focus.
