Reddit mentions of SVBONY Universal Cell Phone Adapter Mount Telescope Phone Mount for Binocular Monocular Spotting Scope Telescope Support Eyepiece Diameter 25 to 48mm

Yes. Basically, these adapters have 2 clamps, the phone clamp and the eyepiece clamp.

The Gosky phone clamp has an adjustable width that accommodates mobile phones from 54-90mm wide.

The iPhone 7 is 67mm wide, and the 7plus is 78mm wide. The Gosky adapter accommodates mobile phones from 54-90mm wide, so you're good-to-go on that.

The eyepieces for your scope range from 33 to 41mm in diameter depending on the particular eyepiece according to this spec sheet.

The Gosky's eyepiece clamp accommodates eyepieces from 32mm to 62mm. Your scope has 1.25 inch eyepiece (32mm), but the back barrel (dimension D) ranges from 1.3 to 1.6 inches (33 to 41mm) so it should work ok, but it will be near the end of the thread of the eyepiece clamp.

Browsing Amazon I ran across another phone adapter by SBVONY with the same design but it's a little smaller. The SBVONY eyepiece clamp accommodates 25mm-48mm eyepieces. Your 1.25 telescope eyepieces are right in the middle of that range. I think this one would be a better fit.

Any other differences between the Gosky adapter and the SVBONY? About $7. hehe I'm happy with my Gosky adapter. The build quality is good. I got it to use with this monocular which has a large eyepiece.

If you go with the SVBONY, and I don't see why not, it actually suits your scope better, you could add a Bluetooth remote for $7. A remote lets you snap pictures without touching the equipment. This helps reduce vibrations, which is good.

The design of the Gosky and the SVBONY adapters is basically the same. You loosen both of he clamps, get the phone's camera in position over the eyepiece, and then tighten them up. This can be a bit tricky at first as you angle the phone to get its camera in position, but you get the hang of it. I took a look at the video of the Orion SteadyPix EZ Smartphone Telescope Photo Adapter and it has a better design that makes the setup easier. It has an auto-centering feature and longer fingers on the part that clamps down on the eyepiece. The only downside is it costs $90. If you're thrifty like me, go with the SVBONY unit.

Suggestion: Get a good 25mm eyepiece. Unfortunately for me, I've discovered older ones tend to be better, in any sort of generic kit like that. I tend to use a MA25 (came with the Meade 6600), 9mm (also came with the Meade) and a 4mm (Celestron Omni)

For visual observing, I wasn't a believer until I compared the MA25 from my Meade 6600, with one from an ETX-70, and a Celestron 25mm from a 130SLT. Each was an easily observable step down. (I have some Tasco ones which are worse still.)

Alternatively, if you have a DSLR, get a t-ring and adapter. You'll be able to do a bunch of cool things. If you've got good tracking, you'll be able to get good images. https://imgur.com/a/1QGAI - Most are from a Meade 6600, which is almost exactly the same as yours. 152/760 f/5 in terms of optics, and if it's the sky view deluxe as your last post indicated, almost the same mount.

I can't recall if that Orion image in the album was with just a tracking system, or with Onstep. It's not Hubble, or even one of the big scopes, but you'll be surprised what you can find using a camera on a scope like that.

I've motorized mine with an Arduino using OnStep (https://groups.io/g/onstep/wiki/2D-RAMPS14) Which also gives me the capability to guide it for longer exposures. (Though I've almost gotten the tracking good enough, that when I use Ekos/kstars to help align it, I can often get 180 to 300 second exposures with minimal issues, without guiding.)

I have this barlow lens (https://smile.amazon.com/SVBONY-M42x0-75-Connect-Interface-Telescope/dp/B0169QR8OE/), and I have no complaints, and it has a T-ring built into it, which is great for me. (Their 5x barlow, I do have issues with, as well as every other barlow I have. An old Meade one was so bad, I removed the lens and use it as an extension tube only now.)

Oh, and with a 25mm, your FOV will be close to what the pictures have (but with a round perspective.)

If nothing else for imaging, get something like this: https://smile.amazon.com/SVBONY-Universal-Binocular-Monocular-Telescope/dp/B01K7M0JEM/ which holds your cell phone, if you've got one that allows for any control over the camera, as it will work through your eyepieces. It won't be great, but most people would probably be surprised.

Hope that helps, and gives you some ideas. (Or someone comes and corrects me!)
