This is the same deep sky object that I shot with my K3, but instead it was shot with a cooled dedicated astro camera.

This was shot over two nights at Parsley Hay in the Peak District,

It is 100 x 300 second exposures. It was stacked and stretched in Pixinsight, and post processed in PS with TopazAI Denoise.

Meh I've taken better with my Nokia N95.

It's nowt really, nothing special. Trust me. It's certainly not awe inspiring and utterly breathtaking. Or terrifying. No way.

I can't print my (audible) reaction. The first word is not allowed and begins with F and the second was "Nora !"
The specialized cooled camera clearly isn't a Pentax (?) but we can let you off that!

Harris got it right ..... "Terrifying" ..... Just what is our relationship to that?
Both the *istDS and the K5 are incurably addicted to old glass

Stupendous!

Link, please, so we can compare.

Is it the cooling that makes the astro camera so special? Or something in the electronics? Or is it an iconograph imported from Ankh-Morpork?

No offence but as I understand, only photographs taken by Pentax or Samsung camers are allowed on here, so what camera make did you use?

It is in the gallery!

To be honest.... its not in the same league, also I think I went a bit ott with the ISO! Gonna try again with a much lower one.

Its basically the cooling that makes these better for astrophotography. Running a 5 or 10 minute exposure can generate heat leading to sensor burn. A cooled camera prevents this, and also makes it more sensitive to light. Using a DSLR for astro, you have to leave a gap between exposures to let the sensor cool down. Rule of thumb is whatever exposure you use, you use half of that to allow cooling.

No iconograph, as much as I like it, it's a pain in backside as I usually get Cohen the Barbarian pestering me for hemorrhoid cream

Its a ZWO ASI183MC Pro One Shot Colour Dedicated Cooled Astrophotography Camera....

And no its not just those cameras you have mentioned. Others can post images shot with different makes on the odd occasion. Just not on the gallery (altho a few have slipped thru the net) or on the Your Photos section of the forum.

The camera used for this image is a highly specialised one, and I did ask if it is ok to post them. This is why they are posted in the General Photography section of the website.

This is it....

Yet again, amazing output from you.

Cooled cameras. In 1991 we were using modified Sony Betamax cameras, liquid Nitrogen cooled for industrial thermal imaging applications. Then FLIR kit adopted Peltier modules for cooling which I suspect your camera uses.
