Re: A Comparison
Personally I find zoom eyepieces a bucket full of compromises at any price point.
I imagine they are like regular eyepieces where you pay for that small increment of performance over similar styles.
The only zoom I have now is a Vixen LV and that is mainly relegated to solar observing.
I prefer the variable focal length eyepieces TeleVue 2-4, 3-6 and Antares 5-8 for consistent

Mark IV has great following for a good reason. It is a high quality zoom packed with features.
It has wide

But lets consider your scopes. The highest power you can achieve with NP101 and Mark IV is 67.8x. Everything will look sharp on axes with pretty much any

Re: A Comparison
Good points. I use zooms mostly for bino viewing and at high magnification they’re just a trifle less than fixed focal length eyepieces. I also use them to make a decision about which focal length is optimal. So I’ve a pair of the Baader zooms and a single Vixen.Bigzmey wrote: ↑Sun Jun 05, 2022 1:21 am I don't believe folks buy Baader to show off. While this is a good quality brand it is not as hip as TeleVue or Takahashi.
Mark IV has great following for a good reason. It is a high quality zoom packed with features.
It has wide FL range (8mm-24mm), long eye relief (19 to 16mm), wide field of view (68 to 48 degree), clickstop (particularly important for binoviewing) and high transmission, high contrast, low scatter optics. Some of these features can be found in other zooms. But it would be hard to find another zoom which has them all.
When Baader says high transmission, they really mean it. Mark IV picks faint DSOs better than quite few other zooms and fixed FL EPs I have tried.
But lets consider your scopes. The highest power you can achieve with NP101 and Mark IV is 67.8x. Everything will look sharp on axes with pretty much any EP at 60-70x, in particular on bright high contrast targets like Sun or Moon.
However, put 6" Mak or 8" SCT on Jupiter or Mars during opposition at ~200x and the difference in sharpness and level of details between Mark IV and lesser zoom will become quite obvious.

Re: A Comparison
I don’t understand. The click stops are at different effective focal lengths. This is very convenient for bino viewing.

Re: A Comparison
Yes, understood and fair enough. The thing is that eyeballs and practice with them differ a lot. I've been observing for over 65 years and have played with zooms for 50 of those. I haven't tried the Svbony zooms and probably won't. I did try (among others) the Vixen LV Zoom at $170 and the Baader Mark IV Zoom at $300. After trying them monocularly I resold the others and doubled up on the Baader for binoviewing. To my eye the Baader was a little bit better than the Vixen which was MUCH better than the other candidates.LDW47 wrote: ↑Sun Jun 05, 2022 2:09 pm Please bear in mind that the issue I am pointing out is the wide range in price between the zooms in relation to any added performance on any given nite ie what your eyeballs actually discern. Obviously the higher grade of scope is a big factor but higher magnification not so much to the average astronomer because as it climbs degradation in the finest of details is a nature of the beast save for absolutely all round perfect sky conditions. In the vast majority of cases, in my extensive experiences ! So the bottom line is $100 C for a great performnce or $350 C for about the same performance 95% of nites, its simple ? Just IMO and observations many times under Bortle 1 skize.
So I am a bit skeptical that the price difference is not justified by performance. To my eye, it almost is. The Baader is twice the price of the Vizen and the improvement in optical performance is slight. I went with it anyway because of the great convenience of the click stop for binoviewing.
I'm not knocking what you saw. I'm just saying that it doesn't fit with my experience.

Re: A Comparison
I think we are sort of on the same wavelength here, just placing empathies on different parts. Let's go with computer analogy. My work computer is 5 years old, but it is just fine for the purpose. I don't have any desire to pay $3,000 for an upgrade which will not change my office productivity. My kids however keep upgrading their computers to keep up with gaming, streaming and what ever else kids do on computers. I know enough to realize that their computers are much better, and in fact some apps they use will not run on my PC. But, for my purpose my old PC is just fine.LDW47 wrote: ↑Sun Jun 05, 2022 2:09 pm Please bear in mind that the issue I am pointing out is the wide range in price between the zooms in relation to any added performance on any given nite ie what your eyeballs actually discern.

The same applies to astro gear. It may appear that the prices are inflated, but on average you get what you pay for. I don't like 95% performance statement, because it is misleading. Let's say I am observing galaxies and there is a faint galaxy on the edge of my scope detection. I will be able to detected it with high transmission
Another example, I observed Jupiter with smaller scopes many times but never saw Great Red Spot or moon transit. When I switched to 8"
I know that not many casual observers care about faint galaxies, but most of them get excited seeing

Re: A Comparison
I am not saying Morpheus are bad (they seems to have good following), but they are not for everyone. If you don't see any need for Mark IV, it will be easy to sell on astro classifieds.

I had great expectations for Morpheus line and at one point got Morpheus 12.5mm to try. I could not stand it. Eye position was hard to maintain and moving the eye with FOV caused blackouts. I have sold it next day.

I have not finished with the IV yet but that may happen because I am not a very consistent zoom user, mainly now for solar WL andBigzmey wrote: ↑Sun Jun 05, 2022 7:30 pm Funny that you mentioned it.
