It’s hard to take a poor picture in the Canadian Rockies, this with an IPhone 7 plus

Had a weekend at the track, and had a little bit of time for playing with my camera...

Still learning - from our light polluted backyard just using a normal DSLR... and some other stuff...

Wow - thats inredible. I had no idea it was possible to see stuff like that without a telescope the size of a mountain.

How does the process work? Can you see them with before you take the shot or are you pointing at a random piece of sky with a lomg enough exposure and theres enough crazy space stuff up there to make a pic? Are they actual true colour pictures?

thanks.. its a great way of learning about the night sky and the cosmos. ...it all started with just a 200mm lens and taking photos of the moon.

key piece of equipment is the tracking mount. once aligned it points your camera at the correct spot for long exposures. sensors do heat up and generate noise the longer the exposure, so multiple shots are required.
ideally i do at least a hundred two minute exposures for a subject. cameras can take longer exposures, but light pollution, tracking accuracy, wind, vibration all come into play. the mount and camera is controlled via software on my computer whilst i sit indoors. so I do not to get eaten alive by mosquitoes.

with the modest setup i have, most of the time what you actually see in the scope is just a smudge (due to light pollution etc), or just a blank piece of sky if the object is in an invisible spectrum (infra red). the magic happens when the photos are stacked and processed. dslr's have rgb sensor, so the colours are i guess 'true colour'. i do use a filter which cuts out most light pollution, and a secondary camera and scope for auto-guiding (it locks onto a bright star to guide the mount to a specific spot).

of course one can always get A Bigger Scope, sturdier mounts, dedicated astro cameras... others end up converting their garage/house to an observatory, or even rent space in a remote location - all of which costs $$$. processing is also a skill, colours are enhanced, brightened etc. the 'artificial colours' come in when folks use dedicated mono cameras, where they can take longer exposures in specific wavelengths using filters...

one can also just google for the photos - but hey what's the fun in that? :-)
