Has anyone tried the Celestron spotting scope zoom? It's specifically for the Regal M2 series spotting scope (comes with most of them) and it's more expensive than the basic celestron zoom.

Thanks for the input, everyone! Your comments are much appreciated. It's interesting that meade and celestron are the same eyepiece. I wish i could afford a televue, but not at the moment. Next EP after this will be a 2" wide view. 30 to 50 mm, to look at andromeda and such.

These are the wide view I use in my 8" Dob.  I have the 2" 38 mm from the SWA 70 degree line.  I also have an ES 25 mm 70 degree.

I have a Meade and a Baader and like them both alot

I have the Baader also, it was my first eyepiece, after reading it was the only "good" zoom. Now I wonder, how does it compare to the less expensive ones?

It's been my experience with tools that anytime you try to make one tool do too many things it never really does anything as well as a job specific tool. A Shopsmith is a perfect example; the zoom eyepiece of woodworking tools. While it boasts at least seven different functions, only two are really viable for quality woodworking operations, and switching from function to function is an onerous task in a production oriented shop. I own two of the older series, but each is set up as a permanent function tool; one merely needs to walk up to the tool, turn it on and go.
 I also own the Celestron zoom, and it lives in my eyepiece case surrounded by explore scientific 68* and 82* eyepieces. It does not see much use, as I find the view too restricted, and, I don't know, uninspiring. The wider, brighter views of the ES eyepieces are just so much more vivid. I guess it's a handy tool for outreach, or a quick grab bag scope kit, but for a quality observing session, I'll take a selection of nice eyepieces over the zoom every time.

These cheap zooms are great for one thing....learning what you like such as fov, specific fls, framing an object etc....they're great learning tools for selecting your eyepiece collection.

I've also had Celestron and Baader zooms. OK for a time, as one "grows up" into knowing what magnifications are useful for ones scopes.

Eventually most with larger aperture scopes with their associated smaller fields of view will go with the larger like, 82deg oculars, when you realize that a 40deg FOV just doesn't "cut it" anymore.

I suppose if your using a smaller scope a good zoom may be a long time accessory.

The other downside of zooms is the mechanic aspect, which can give trouble like seizing under cold conditions, or coming to pieces under continual frequent usage.

I own a line of high-quality Pentax XL eyepieces, and like them a lot. But in some ways I like my Vixen Lanthanum 8-24 zoom even better. I love the convenience of being able to "dial in" whatever magnification I like, and I adore its portability. As for field of view ... yeah, it's kinda nice to have a wide apparent field of view, but it's really no big deal as far as I'm concerned.
