Telescope Build for Deep Space photography

$1K Scope (main and guide)

$1K Mount

$1K Cameras (main and guide)

$1K Filters, Focuser, software, other misc

I also suggest starting with a small refractor around 80mm aperture, as it makes everything simpler to being with. No fiddling with collimation. There are lots of large deep space targets to start with.

I also forgot the tripod. Look for second hand items that aren’t the electronics.

i’m looking for advice on the best deep space Astro photography telescope build with a $4K budget.

Do you have anything in particular you’d like it image? My thing has always been Nebula.

But there are many targets out in deep space. Galaxies, Clusters, Nebulae, Etc.

When I was starting out I spent 5 months building wish lists as I studied how to get out there.

I began with an 80mm triplet Refractor. It kept me fascinated for over 9 years, then the update bug bit me.

It’s a tough nut to crack when you are starting out. This is an expensive sport to start out in.

It’s been said, and it is true, the mount is the most important for Astrophotography. It is the foundation for whatever telescope you choose to start with. And it needs to be one designed with AP in mind. You would find poor success with the wrong mount. I made that rookie mistake.

My ED80T CF telescope was good for what it was. And now it lives with 3 of the grandkids and they enjoy the heck out of it. So as long as it is bringing joy, I’d say it was worth the $1000 it cost back then. They just use it for visual. A triplet refractor can do both easily, other telescopes not so much. it depends on which style they are.

Then comes the camera. best to invest in a true Astro Imaging camera. they are built to do the specialized work of AP.

You could probably stretch your money pretty far buying pre-enjoyed equipment. It has its risks though. There is something to be said about having a warranty in case the part turns to crap on you.

In spite of a very rough and rocky start for me, I’ve persevered and kept going. I didn’t get so frustrated that I gave up. Oh, I had lots of nights I quit. But I came back out the next night and kept trying. After a while I began winning. I took thousands of picturds. Then I’d get a picture here and there.

Have you considered something like a SeeStar or equivalent? You could enter with one of those types and then down the road get more expensive items. Or not, just work with a SeeStar type and learn how to coax the best out of it. I’ve seen some impressive images from them lately. They basically have a cell phone camera in them, and electronics to make them practically self running.

Los of ways to skin a cat, without breaking the bank.

I would recommend a short or mid-focal length triplet or petzval refractor (200-600mm) (with flattener/reducer if not a flat field scope), an Eq6r-Pro or equivalent mount, a 585 or 533mc pro for main camera, ASI 120mm mini or 220mm mini for guiding, a small 40-50mm guidescope, EAF, and AsiAir controller. You can find these items used to save money and you'd probably be well under 4k, with enough saved to buy a filter drawer and a couple filters (maybe a UV/IR cut and duo-band filter, or perhaps a LP filter if needed).

USD 4K is a decent budget to get started with Deep Space Astrophotography. But may need some tweaking if you want to have a decent gear

1. The most crucial aspect is the Mount. No compromise here. Recommend a Harmonic Mount either a ZWO AM5N - USD 2200-2500 ( approx) or at least a ZWO AM3N - USD 1500 if you want a smaller payload. Preference would be for AM5N as once you go for bigger and heavier scopes later , then no need to change the Mount.

2. Recommend going in for a good Refractor scope for Astrophotography. Can range anywhere between USD 600-1000. William Optics, Askar, Takahashi are good brands to choose from. A lot of pre owned good scopes are available at lower costs around USD 500-700/- Also look for Clearance Sale options from various stores in your area.

3. Main Camera. Would recommend ZWO ASI 533 or 585 MC which is one shot color camera (OSC) to start with. Prices range from USD 600-800. Higher end cameras are between USD 1500-2000 Range

4. Guide scope (50-60 mm)and guide camera (ASI 120 MM) - Approx budget USD 250-300

5. May need a Controller like ASI Air Pro . Cost would be around USD 250. Alternatively if you are a Windows user you can work with N.I.N.A which is open source and is free

6. If budget permits you can go for at least one of the basic filters like Optolong L-Quad /L -eNhance an be another USD 150-200

7. For Image processing a lot of Open Source Software is available like Siril, Graxpert, GIMP etc. No need for licensed ones like PixInsight to start with.

   So most of the above gear should come within USD 4000-4500 range

Hope this helps

I wouldn’t argue with any of the suggestions - of course the mount and tripod being most critical.

The new harmonic drives like the AM5 paired with a solid tripod would serve you well.

A small Apo would be the most trouble free scope, but I have been very happy with my 150mm F4 newt (once you get it dialed in)

Fast data acquisition, good star quality, lightweight scope (easy to guide accurately) and

Cheap! (comparatively speaking)

Rick

Much cheaper, not to mention more aperture than most refractors and no concerns about color correction. I’m surprised that newts in the 6” class aren’t more popular.

My final two “Wish Lists” were an Astrograph Newtonian, and a carbon fiber Refractor. My final choice was based on reflectors being finicky and fiddly. (once you get it dialed in) The CF refractor is still in use by two of our Grand Daughters for visual. Something an imaging Newt cannot do. More Here.

So, lots of choices. I’m not yet enthused with the harmonic drive mounts either. But hopeful they improve the tracking and guiding figures. They are still relatively new to the field, so I really expect improvements. But there are many more and better choices than when I was beginning.

Choose what can “Future Proof” you. When I got my mount my ED80T CF looked ridiculous on it. But it was rock solid and my stars in my images immediately shrank to tiny dots, and my focus improved. My 17 pound payload was quite short of its 50-pound Photographic Instrument rating. That’s why I call it my forever mount. It will be inherited after I’m gone but still function rock solid. But my equipment today was impossibly out of reach when beginning. I wasn’t even sure I would be able to use the equipment. So a huge investment just wasn’t in the cards then.

SAL-33

Looks like it has some real potential. Breaks away from the ZWO sphere of software. Seems good for those of us who prefer to use independent equipment.

Same 44 pound upper capacity. I wonder when they will get a higher capacity in these harmonics? Or is there a threshold these harmonic mounts can’t cross? (I prefer to stay well under the max.)

Cuiv reviews.

Thank You John for the lead!
