This respected reviewer certainly thinks highly of it:

I have not tried one myself but I do have the ones that he compared it with and they are excellent.

Without the lower lens group in place the Hyperion does indeed become a ~22mm eyepiece. Unfortunately it's not a very good one though.

I still have and frequently use the small format Pocket Sky Atlas. I had Interstellarium and the All Sky Edition of Uranometria but found that I didn't use them much so I moved them on.

Recently I have been finding Stellarium or Cartes du Ciel very useful. My laptop is always close to where I observe from so it's easy to refer to those. Stellarium goes down to mag 15.

I have some apps like Sky Safari etc as well but I don't tend to have my mobile when I'm observing.

I don't have any of the ones that I started out with. I have some photos though. Initially I used a .965 inch set then moved to 1.25 inch set of varying quality.

My longest owned eyepiece is this one which I have had for 10 years or more:

@John is that T-Rex encoder fitted?
 

Yes, they are fitted on both axis. I have all the cables as well, Just need the DSC unit I suppose but it's not really a priority for me.

I am late to this thread. My TV NP101is on a Vixen GP DX

The system seems to think that the file type is .heic which it can't handle.

Can you post the image in a different format such as jpeg ?

Stellarium shows you the split between the components but not as far as I know their respective magnitudes.

I've found this database pretty useful:

Plus the great Star-Splitters web site of course:

The Cambridge Double Stat Atlas is very good if you can find a copy.

The International Space Station passed very close to that part of the sky on that day. It was magnitude -2.5 so pretty bright. The UK time of the ISS pass was around 22:00 hrs.

....Think about a planet, details within Jupiter's belts or the cassini division in Saturn's rings is easier under higher mag even though these both dim appreciably under higher mag. Seeing individual small details, such as a single star within a globular cluster are easier with some magnification...

.

Just a small point but, visually, details within Jupiters belts tend to get better defined when you back off the magnification rather than increase it. I think this is because they are low contrast features rather than the high contrast of, say, the Cassini Division.

Probably not really relevant to the overall topic though.

I think FLO should introduce a "scratch and sniff" facility on their website

Hmm, I'll take your word for it.

Smaller than @Rainmaker's 152

I'll have to post up my 120 soon. When was that color scheme available?

That was the first colour scheme that the ED120 was available in. The ED80 and ED100 were supplied for a year or so before this in the Skywatcher blue colour scheme.

...Not sure if you saw the heads up about the conjunction with Mercury on 21st and 22nd. Should be good if clear.

I didn't see that - thanks

I think it's a Tasco 114mm newtonian or similar.

It is pointing away from the window. You do seem get this when scopes are used as props - especially newtonians

I think this was an advert on US TV:

This is a very comprehensive comparative review of a great many 24-26mm eyepieces, including the 2 you asked about, by Bill Pasolini.

I think that is the same link that vlaiv posted earlier.

It is a good review though

...How much longer do we think it will be possible to observe it for? A week or so?

I guess about a week. It's getting close to the conifer hedge at the W end of our property by the time it is easily visible now so I'll have to start finding it a bit earlier I think.

I owned the ES 24 / 68 and then got a 24 Panoptic. Very little in it in terms of performance, maybe nothing much of the time.

I just wanted another 24mm Panoptic though, after selling one a few years back and regretting it

I've got an old Fuji Finepix S5800. I've been meaning to try it out for eyepiece projection images of the Moon etc.

This one tonight. I ought to have been consistent with my labeling though .....

Do you still have them John, I liked mine when I had them but at the time I was still trying to view with glasses and despite the good ER,  I did prefer the Delos I owned too. 

Yes, I have the 10mm, 7mm, 5mm and 3.5mm Pentax XW's. I love them

Smaller aperture, quality optics, seem to be able to do a better job in cutting through the seeing than larger ones.

Used to have the 3mm and 4mm Radians. One I liked and the other I found gave rather odd stray light issues when used to view the Moon. I can't recall now which was which

They were replaced by Pentax XW's in my eyepiece case.

The longest slo mo cables I have ever seen! 😉

With the long refractor, you need them !

One thing I would add is that I use the 21.5mm-7.2mm zoom + Baader 2.25x barlow combination a lot for high power observing. The optical performance of that is pretty good - it gives me a 9.5mm - 3.2mm zoom. Probably not quite as good as the Nagler 3-6 would be but pretty close and for about 30% of the price. 

Mine is even smaller !
