Ethos - First Ever Look T hrough One


Pig

Recommended Posts

Just a quick note about my first experience with a 100 degree eyepiece.

I took a trip over to our groups dark site last night and I had my first look through an Ethos :laugh:

I am certain it was the 15mm and I have to say I can really see what all the fuss is about, the view was absolutely wonderful :laugh: 

The scope was  an APM 100mm refractor thus the Ethos was in very good company and I was looking at the Double Cluster.

I see what you all mean about an immersive view, I felt like my head was going to fall into the eyepiece and get stuck !!

I think I am have to invest in a green & black 100 degree eyepiece :smiley: very soon

I couldn't agree more shaun, It only takes one look through one to realise what all the hype is about and if I ever get serious about visual again, myap gear will be used to fund them etho :)

Cheers Stu, It must have been the 13 then, I am after a 17mm eyepiece to bridge a gap I think I will have to start looking for something.

I sorted out my 2" diagonal focus issue last night, and all is fine now. It turned out to be the locking mechanism :laugh:

Scott, It certainly is worth the outlay fantastic views. I will have to keep my eyes peeled for one :smiley:

There is something about the contrast with TV eyepieces, they have it sussed :smiley: I remember the black background the Delos 17.3 used to give, I haven't seen anything like it again until last night :smiley: Yes they are very expensive.

Pete,

Very different to the plossl because of the field of view.... it really is like sticking your head through a porthole and looking around, very cartoonesque :laugh:

Sounds like you enjoyed the experience, i would love to compare them to my TV plossl's!

I have a number of Ethos eyepieces and a set of TV plossls so I do this comparison quite often. The plossls provide very comparable quality views within the contstraints of their 50 degree field.

I would second John's findings re those two groups but would extend the comment to include al the ranges I have, once you get to tack sharp there is really no where else to go.

Shaun,

What have you done apart from entered your wallet for slimmer of the year.

Alan,

Astronomy / Solar has helped keep my wallet very slim for a few years now....... and I don't see it putting on any weight for the foreseeable future :laugh:

Great eyepieces though ..... I will try to restrain myself and wait for a second hand one to come along :smiley: I am not very good at the patient game though.

Shaun,

I don't have an 80mm APO like you but I bet something like either the 21mm or 17mm from a really dark site would look fantastic, I use my 115mm F7 which doesn't have the size of field yours will offer and it still looks great.

Yes Solar gear is a price, something that I have never really thought about. Only time I have done any was back in the mid 70's with my little 3 inch and a projection box I made, sunspots looked good.

Alan.

I couldn't agree more Alan :laugh: something along the 17mm should be fine. I am not sure the max coverage I can get from the scopes, the field stop confuses me, but the maths without it is 3.4 degrees with the 17mm :grin: all at f5

Hi Shaun,

Field stop calcs are more accurate for wider field eyepieces approaching the barrel size limit for each format. Televue put all this data on their site so it's quite straightforward.

Fov = (Fieldstop/scope focal length)*57.3

For a 21 Ethos in your Esprit that's a 5.18 degree fov!

After getting a 13mm Ethos I've started to ponder about getting a 17mm. Even though I have a 17.3mm Delos, but I like the wider fov of the Ethos. Oh dear, more expense! :)

It's a horrible affliction Richard ;-)

I have the 13, 17 and 21 and they each have their place, particularly with a variety of different focal length scopes.

Cheers Stu ... that's over 10 Moons in one eyepiece..... maybe they should have been called "Tardis"

It sounds like I would be wasting my time asking for recommendations then, as they all sound good :smiley: even so I do wonder which one will suit my 400 and 500 focal lengths most (forget solar system objects as targets I am happy with the SLV's) but clusters such as Hercules, the Wild Duck and the Double I like lots :laugh:

LoL Mike..... I have fell in love with refractors I am afraid..... I like my lovers to be slight :laugh:

Fine until you have a fling with the deeper sky, or so I found after being a die hard refractor user for many years :smiley:

I would love a big DOB I am just not sure it would get used as often as it deserves whilst I live in a town...... I have no doubt that I will get one as soon as I move to a more rural location :smiley: So rather than a fling I would like it for keeps :grin:

I have been seduced by the temptations of the large dob too John, and really 'get' what they have to offer, but I still find myself using my refractors more often.
