I would certainly recommend it, you could always return if you had to.

Re: Celestron 24mm Ultima Edge
I am not against used but up here in Canada it will be almost impossible to find one in a timely way unless I just hit it lucky. I don't intend to wait forever until one might happen to show up on the used market, it could be a long time, if ever. It took me a decade to find an NP101 up here in Canada, the astro market is pretty thin and restricted.Lady Fraktor wrote: ↑Sat Feb 18, 2023 8:00 pm If you do not mind used, the Vixen 22mm LVW is a much better eyepiece

The modern equivalent to the LVW 22 is the Astromania SWA/Omegon Redline 22mm which is easily the LVW's equal.
But, it is a 2", where the LVW was a 1.25".

Re: Celestron 24mm Ultima Edge
I may have a biased opinion on the LVW as they are still here whereas the Hyperion and a set of Radian were moved along.
I will say that I do like the Hyperion 31 and 36 mm though.
The Morpheus are very nice and I find they are much better than the Hyperion.

Re: Celestron 24mm Ultima Edge
Thats why I switched to he Morpheus line from the Hyperion line but right now as per this thread my focus is on the 24mm Ultima Edge to go with the Morpheuses and to replace my 21 Hyperion.Lady Fraktor wrote: ↑Sun Feb 19, 2023 3:34 am LDW47, when I compared the Hyperion I found that the LVW overall view sharper and more pleasing. Not as much detail and something about the Hyperions just struck as being a bit 'soft' in the overall view. Refractor used at the time was a TMB 105 mm f/6.2

Re: Celestron 24mm Ultima Edge
I would suggest the 30mm UFF instead.
First, it's a seriously larger true and apparent field of view.
Second because the field is flatter.
Third, because the edge of the field is sharper.
Fourth, because the magnification is a bit farther from the 17.5mm.
Fifth, because it works better in shorter
Sixth, because it is a bit more glasses-friendly.
Seventh, because it has less chromatic edge-of-field issues than the 24mm.
Eighth, because the field stop is in focus.
Yes, it's 2", but it's a better choice for a lower power and WAY, WAY, WAY better than the 31mm Baader Hyperion.
It's a high-end eyepiece with an inexpensive selling price.
It's available in the same brands as my earlier post in this thread.

Re: Celestron 24mm Ultima Edge
I already have the 30mm Edge (2") with great views but I want the 24mm to use with my smaller scopes that are restricted to 1.25". As far as being close to my 17.5mm Morpheus, sometimes i like just a little more or less mag. on those certain nites, its my viewing habits and it works for me.

Re: Celestron 24mm Ultima Edge
24mm is ~1.4x step from 17.5mm. I would not say it is too close. Depends on type of targets. For faint fuzzies I find 1.3x - 1.4x spacing about right.LDW47 wrote: ↑Mon Feb 20, 2023 5:14 pmI already have the 30mm Edge (2") with great views but I want the 24mm to use with my smaller scopes that are restricted to 1.25".

Re: Celestron 24mm Ultima Edge
Example: 1250mm focal length:
30mm = 42x.
24mm = 52x
17.5mm = 71x.
The 30 to 17.5mm jump is only 29x, which is a small jump in magnification any way you look at it.
If the focal length is shorter, that jump is even smaller and makes even less sense.
And a 1.4x spacing is too much at high power.
300 becomes 420x, and most people would say a 120x jump is a bit too large when you might be bumping up against seeing.
So, though the 1.4x rule is followed by Pentax XW and Baader Morpheus in the focal lengths sequences, it doesn't always work.

Re: Celestron 24mm Ultima Edge
In a very small scope, or for terrestrial use, that could be a 20-30x magnification change.
But by the time you get to an 8" scope, 50x, 100x, 150x, 200x will work fine, and that is an increase from low power of 100%, 50%, 33.3%, 25%, etc.
You might prefer a smaller jump than 50x, but I've owned and used scopes of 80-100mm, and almost never did i find that a magnification change of less than 30x was worthwhile.
Even in my current 4", 40x jumps seem fine: 30x/70x/110x/150x.
Because I have a larger scope, with a longer focal length, I do have other eyepieces, but those 4 are close to all I need in my 4"
So a flat % change just doesn't work if what you want to see when changing magnification on an object is a different view of the object.
A further example: My 12.5" scope with a 40% change, starting at 100x:
100x
140x (a reasonable jump)
196x (a tad too much change, but I could live with that)
274x (this might be stretching a bit, but I could see it for certain objects)
384x (this magnification change is a bit excessive. I'd find myself wanting something in between, a lot.)
538x (I can use this power fairly often because my site has good seeing, but the jump is just too large. Seeing dictates the maximum magnification, and the jump would be too large too much of the time).
The point I'm making is that the % change should be determined by factors other than a % change. If the object barely appears any different when changing magnification, then the jump is too small.
I say that knowing I have too many eyepieces and need to get rid of some. That's a Sophie's Choice when you love them all.
