Astrophotography has been called the rabbit hole of astronomy. Why, well it can suck you in as many people find they always want more, more equipment more dark skies more time

I am starting this thread to give people who are interested in dabbling in creating astrophotos with a DSLR a place to find out information and ask questions. I am not an expert but I have been doing Astro and Solar photography for at least 20 years or more. I started from my backyard with a camera and a tripod, there were more bad images than good images for sure.
When I first started I could see the Milky Way from my backyard and took some images of it, then they built a major mall 300 feet away and a factory 600 feet away and the "automile" in Norwood MA started getting more dealers. Now I cannot see the Milky Way on the darkest nights in fact I really can't see a complete constellation, sometimes the Big Dipper but it is hard to see all the stars. My skies are Bortle 7.5 to 8 (Bortle is a sky darkness scale).
That being said there are filters that can be purchased to cut light pollution, although be away with the new LED lighting in many streetlights it is in the same wavelengths as many deep sky objects.
My progression in AP was first from my backyard with a SLR, 36 shots and no stacking images, man how many satellites there are up there to ruin images.
Next I joined an Astronomy Club in Rhode Island and was able to set up at their observatory
then I got into digital and what a difference.
I still do Solar and Lunar from my backyard and have purchased 8 telescopes and 3 mounts (tripods on steroids) DID I mention about the Rabbit Hole?

Currently with my mobility issues and liking my sleep I am using a remote subscription observatory called SLOOH. Most of my imaging is now done using their telescopes remotely over the net. They have observatories in the Canary Islands, Chile and soon Australia. They also have a solar scope. There are other amateur hosting facilities but they are much more expensive and the advantage of SLOOH not just the cost but the fact that you can watch a live feed from each telescope even if you are not imaging and you can see the scope slew (hence the facility name SLOOH) to an object and then the object appear and become finalized. You actually control the scopes and tell it what to image, even just a blank area of sky. One thing to warn you about besides it becoming addicting is that they don't guarantee a good image every time it is just like you using your own gear with satellites, clouds, moonglow, planes, wind rain etc. Other subscription scopes you tell them what you want to image and when they have enough people who want it they will take the image, may be 30 days later. SLOOH you can point the scope at the same time you are observing.
Slooh has 7 scopes in the observatories, a 20" 2- 17" 2- 14" 1- 11" and a 90mm all available to use. The 60mm solar scope shows the sun every day that it is clear and you can watch it and even take snapshots with it although you don't control that one.

I will be adding posts to this thread, don't want to overdo a single post.

As I mentioned the amateur hosting facility SLOOH is great for astro imaging and learning the night sky however some people feel it is cheating as you don't have to buy your own equipment and can use equipment that few of us can afford, sort of like renting a R3 or a large fast lens at Lensrentals, they don't complain about that do they?
However a quick word of warning most of the data used to get a good image requires several software programs to get images, such as "Pixinsight". It can be done with lightroom photoshop gimp or other programs but Pixinsight is the one I use.
But that warning aside every imaging run, they call them missions, also provides you with a PNG image, over time you will learn how to stack png images to get better results.

Check them out they have an "Apprentice" membership for $200 and an "Astronomer" membership for $600, I have two Astronomer memberships that for now I was grandfathered in before they raised prices. I highly recommend them as it is fun to just watch the solar scope or the different missions to deep space!

If is a quick snapshot I just took of the sun a minute ago, oh and you can take as many images as you want there is no per image cost or limits other than an Apprentice can set up one imaging run at a time but as soon as that completes they can do another and another, unlimited. They can also "piggyback" join someone else's mission, an Astronomer gets 5 at a time.

as you can tell the image below is soft just the way I got it from Slooh, you need to use PS or Topaz to sharpen it up and remove noise

Subscribed. This is definitely a area of photography I would love to get into. My plan is fairly simple. Start with a decent tracker and use my camera and 600mm lens.

I agree with the decent tracker, I have one made by Skywatcher, but I would start with shorter lenses at first, even a 50mm, but say a 135mm. If you try for too much at first you will get frustrated.
Remember AP is a rabbit hole!

I got into digital photography, I am well versed with rabbit holes. :)
 
AP is one of the reasons along with nightime photography, if not the only reason I jumped in neck deep. I've tried a few times with lunar but my setup was a little wonky. Actually the coloring in this picture was almost spot on from where/when I took it in central Alabama.20230304182007_IMG_8452.JPG

I have been out of the "Game" so to speak for about 20 years. I bought my 10" LX200 GPS when they first came out...2002????? I think. I started Astrophotography with that and my old Canon 10d DSLR a whopping 6 Mpix. I also used the Meade LPI and I had a 80MM ORION that I was piggybacking on the LX200. Along with an ETX90 EC. I was on a wedge and boy was it challenging to align and get everything steady enough for astro pics but I did manage to get some decent shots.

Life does what life does and my work schedule changed to overnights, so Astronomy was put on the back burner. I did occasionally take the old scope out and did some visual stuff until one day the mount decided to quit on me. I replaced boards and motors checked wiring and finally gave up, put it back in its box and there it sat for over 15 years.

I retired and got the bug again, so I dragged out the old LX200 de-forked it, bought a Skywatcher CQ 350 Pro, an ASIAIR, An ASI 174MM guide camera, an OAG with all the misc spacers. I am going to use my Canon 60d for now with my 0.63 reducer.

I had the mount and scope out for first light 3 nights ago and did a quickie polar align, a 2 star align and tried out the ASIAIR. Well things sure have changed from 20 years ago!!! lol For the better I must say. Took a few real quick shots of M42 to see how it all fits together and it went beyind my expectations. I will be shopping for a Main Camera shortly (an ASI) but need to do some more research.

Just wanted to introduce myself and give a brief history of my dabbling in astrophotography. Hope to be able to post some pix soon and I'm enjoying the work that you all are posting!
 
Welcome all. My observatory pad survived our major storm today, although my neighbors stockade fence next to it surrounding his pool was blown over by the wind gust. We still have power many don't

Cloudy of course.

I hope to see peoples efforts in the different threads in the astro section
 
I've been shooting night skies for a few years now.

Not deep space though or telescopes. I'm much more interested in landscape astrophotography. Milky Way, Aurora, constellations above landmarks, beaches, etc I've just started with timelapse too since adding an A7Riii - Milky Way and Aurora so far!

I use a combination of A7Riii, A7, 24GM, 35GM and occasionally the FE85 - I do want to try using the 85mm a lot more often. I usually take two digital kits and use a Move Shoot Move rotator for tracked skies.

I very often shoot star trails with my 35mm film camera too at the same time. Although I have used the film camera to track Orion and the Milky Way too.

I am currently thinking of getting the A7 h-alpha modified, or buying another to modify. I do use it quite often for 'normal' photography alongside the A7Riii, so any opinions on that would be appreciated.
 
Thanks Jeff, your thread is helpful.
I'm gonna start with books/websites and a pair of binoculars (my radar is on Canon's image stabilized).
Later I'll expand into astrophotography. I retire next month so I'll have plenty of time.
 
The Canon IS binocs are great I Have a pair of the 15x50's and they show the moons around Jupiter great as well as Messier objects.

It is amazing to be looking through them and everything is shaky and you push the IS button and they lock on and are super stable.

the smaller sizes 7 power and 10 power are great for galaxies and nebulas. they all work great on the moon
