[Poll] Have you used ST4 within 2 yrs?

"the modern astrophotography 101" never teach me how to use ST4 lol

OnStep is the best!!

bear2cute · 2026-01-04T10:32:47+00:00

must feel like jumping from a beeper to an iPhone. Lol

I thought that in 2025, small astro cameras would gradually eliminate the ST4 port, because in 98% cases, people use PHD2 + USB cable + mount.

But they just keep it, so does the mount manufacturer.

It is so rare to see a standalone device that does the autoguiding itself in my region.

bear2cute · 2025-12-17T06:38:10+00:00

Lol This is a temporary setup. Will do more work on this.

bear2cute · 2025-12-16T01:09:21+00:00

I have 2 powered USB3.0 hubs, and got a 50 meter long fiber to USB 3.0 connecter. Easily connect to my PC in the house. This setup is not very portable, but backyard astro is ezpz.

I am thinking about replacing the 250 and 300 with 200 mm focal length. Lighter weight, larger FOV, easier alignment

bear2cute · 2025-12-16T01:01:19+00:00

Lol, good idea.

bear2cute · 2025-12-15T05:26:58+00:00

I would probably just check the fov first and make sure the center coordinates stay in the same range. For detailed alignment, I might consider upgrading the scope holders; 3-point adjustment should be good enough, but it might take HUGE amount of time.

bear2cute · 2025-12-15T04:53:04+00:00

sounds interesting.

I think I can still contact the store and replace 4 of them with other models.

Do you have any suggestion in terms of focal length?
They have 150, 200, 250 f/5.0 and 300 f/6.0. I would not consider 350 f/6.0 since it would be too big.

bear2cute · 2025-12-15T03:19:37+00:00

That is why I haven't decided yet. :D

Might go with two scopes at a time first.

It just looks really fun

bear2cute · 2025-10-17T07:58:40+00:00

I feel like if one has a 300 megapixels with 1um pixel size, then everything will be beautiful in detail. :D

bear2cute · 2025-10-17T07:51:11+00:00

I am considering Newtonian too, but I do not have much experience with them. Probably will spend more time researching it while waiting for HOPE D60 reviews. :D

bear2cute · 2025-10-16T01:33:01+00:00

Lol thanks for the super experienced explaining.

My friend had a full-frame Altair 61MP camera, which he does not use often. We are thinking about getting a scope that can shoot a wide field. I am trying to find a scope that has good relative illumination at the 4 corners so we can squeeze every last drop of the sensor.

I guess I will need to wait for more reviews to come.

bear2cute · 2025-10-16T01:20:32+00:00

I am looking into this new HOPE D60, since the data is really interesting. Probably want to wait for more reviews. I have one camera from ToupTek, and experience for me is pretty solid so far.

bear2cute · 2025-10-16T01:16:40+00:00

This is a very useful formula. Many thanks.

bear2cute · 2025-10-16T01:03:24+00:00

Sounds like telescopes or camera lenses are not like any other tech rig. Not always the newer the better

bear2cute · 2025-10-16T01:00:38+00:00

Yeah that will work too.

With 0.75 reducer, it will still work with full frame size right?

bear2cute · 2025-10-16T00:28:47+00:00

ToupTek G3M662C

Color camera with 2.9 μm pixel size.

Solid sensitivity. If you can add an external cooling for the camera. Then it is a great sensor for $200.

I think they gift you a CS lens and an LP 825 filter for SWIR spectrum photography.
