Hi TriX!
Well, now is a tough time to be breaking in to AP. The market is really dried up for equipment.
What I did (2014) was start by deciding IF I wanted to do this, Then deciding WHAT I wanted to do.
Which is almost the same as what I'm reading from you.
DSO, Nebula specific for me.
The long haul came when learning how to do it and the best equipment to try and start with.
I made the mistake of coming in with a budget mind. It yielded me a great deal of pain and work to fix it. I do hope your entry is a lot smoother than mine.
Now, around 6 years later, I feel I'm managing better images in my way of doing them.
What I came to the conclusion of was the telescope needs to be a camera lens. So I went with an
ED80T CF version with Orion. I'm still using it today.
My first Astro Camera was awful. went through 3 the first year, and never got a good one. A Great Friend watched me struggle and one day offered to loan me a camera.
After instant success with it I wanted to buy it and did. I'm still using it today.
Now, it is said, and from experience now I agree, the mount is the most important part in an Astrophotography rig. My first was a budget mount. But it was problematic.
It finally gave up the ghost in November 2019, and got replaced in February 2020. My new mount completely changed everything about my efforts.
I've strived to improve as I can.
So you said, "Beginner Telescope" but do you mean you need a whole ensemble to start AP?
