beautiful image

looks wonderful

those sony cameras are super sensitive, big pixels....I wonder how good the new one will be ....Surprising only a few frames...it shows less noise with three short stacked frames than one long one.....still difficult to process

Sorry....yes 10000iso ....my Spanglish kicking in again.

Snapped this on my recent visit to Spain. Exposure time was 3x13s on my Sony A7s iso was 10000 darks and flats applied , 20mm Canon prime lens at f4. I didn't have a tripod with me so I had to balance the camera on a cardboard box. Thanks for looking

Wow that stunning Martin...so crisp and deep. You have beautifully balanced the HST colour pallet...top shot

what a stunning rendition...great colour and depth

love this shot

lovely shot...

beautifully done....got love that FOV, really nicely processed

Time very well spent Jonas... If you are going to do an image of one of the most photographed objects in Northern skies then do it just like this. It is a very special image Jonas you have made that AG12 of yours sing. Its been said many times here but really has to be the best M31 image I've seen.... pure class!

My pier was made from a 12inch diameter off cut of air conditioning ducting filled with concrete sitting on a 1m cube of concrete foundation. I used that for a while by it self then built the observatory around it. I did find that it warmed up during the day then radiated heat right in front of the optics at the night, simply fixed with insulation.... its been in the ground for about 15 years still going strong. If i was to make another I would do it exactly the same way.

Flawless!

looks like dust on the sensor, only noticable when the the lens is stopped down and ponting at something bright...but it really could be anything
