Bushnell spacemaster II

Found my old scope last week was buried in a cardboard box, thought i had left it in a hide in 94......more likely my mother had `tidied it up` and that generally meant that it was missing!

I was trying to get my baader zoom attached to it, but so far have failed.

HAve maanged to get a astro ep to screw into the internal thread. Need to find out the focal length to work out the magnification.

Will trial it in the field, but i should be able to improve on the performance....

some pics wheni get around to it.

Can anyone list various eps that fit these, preferable fixed mag wide angle....

edit......`Squeezes an effective focal length of 450mm(f/7.5) into a very compact scope length of 12 inches. Superb optical system includes a multi-coated 3 element 60mm objective, internal 2 element barlow lens, internal baffeling to increase contrast and internal focusing. `

I cant believe its 450mm, it seems too short.....anyone explain this?

Thats a good find..congratulations..Yes,that zoom sucks....Old Kowas and Opticrons fit this scope..I am sure You know that...Viking branded eyepieces possibly too.Anything Old and Japanese is more likely compatible.For modern eyepieces I Wouldn`t know...If you already found an Astro model that can have the barrel removed,maybe thats the way to go..I saw a thread recently,a Nikon 20X WA for sale,that You had...Have you tried that?..
What is amazing is that the scope has 450mm FL...!!..F/7.5!..thats like the Nikon 60 fieldscope..It should be well corrected

yeah i tried all my eps....couldnt get the nikonn to fit( or my kowa...the kowa is very long thing ep, so the focal point was wrong.

gonna need short eps to wirk in this beast)

optics seem decent in this scope, but its tad heavy for the size.....seems to be lead lined.....might survive ww3....which starts in sep :P

No,Sorry..I cant ,..I really have no idea of models in those brands..probably the eyepieces for the TSN1 and TS601 , and even older models..No clue with older opticron either....Check Ebay and the second hand optics shops in the UK,,..Vintage,threaded ,japanese eyepieces...

PD..Okey I did a search on Bushnell Spacemaster Eyepiece in the forum,and found a lot of info...just run the same search and look around..So far I found that Acuter and Mirador eyepieces should fit,also Kowa TS and Opticron HS(pre metric..)..

bushnell spacemaster

hello, I noticed this old thread on a search about the bushnell spacemaster. I just purchased one last week because I have always heard that the meade research grade 20 mm eps would work by taking off the 1 1/4 barrel. today I tried one and can confirm they work well. I believe the meade has a 70deg field. to the best of my knowledge.

eyepiece.

a 25mm bushnell kellner 24.89 from microglobe uk will screw in just enough to hold and gives a nice bright wide angle view. just a thought.

bit low magnification tho? cant really think of a use for that tbh.....anything under 25x is of limited use to my way of thinking.(have a 22x ep already)

will have a peep at it tho...

18mm or 15mm would be good. anything under 13mm is starting to test the outer limits!

Hi,

if it is still f7.5 with ED glass, it could be a nice instrument - 60x should be possible with a good EP, maybe more. Did you have success with astro EPs?

Hello
my first (1984-1998) birding spottingscope was the honored Spacemaster II - not yet this later ED version: for those years, IMHO, a fine and rugged instrument, not sealed inside however (I remember a few case of internal condensation).
In 1990 I picked an Opticron HR 22xWA that worked very fine all around the scope's lifespan - I traded in 1998 with my first ED model, an Opticron 66HR ED- the 20x-45x zoom was optically of lesser qualty, and since then I never removed the good fixed eyepiece.

tbh its a while since I fiddled about trying to attach them. think the bits are scatterd about atmo, gonna have to track them down in the wilderness of my filing system!!

baader hyperion zoom, will screw onto the scope, but dont think it comes to infinite focus, sadly...also its a tad heavy.

i bid on this, but it went for a silly price!

http://www.ebay.co.uk/itm/Meade-seri...-/291889224225

its about the right size of ep to come to infinite focus.

still searching for more....if anyone wishes to donate a televue nagler, feel free :P

But worth it - the SDLv2 is a very nice zoom EP - flat across the field and 70 deg afov at the high mag end. Love it a lot on my old Kowa.

I don't know if it fits your scope and comes to focus at infnity... you'll have to try...

Fixed power eyepieces for the old Bausch and Lomb Balscope Sr will fit the Bushnell Spacemaster II. They were available in 15x, 20x, 30x, and 60x. I have bought them all on eBay. Kowa made a 27x in the same screw mount. I have never found one. Bushnell branded eyepieces included a 25x, a 40x and a 22x wide angle which is just awful. I have tried these only on the Balscope Sr scopes which, if you have a good example that has been seen to by a tech who knows what they are doing and has glass in good shape, can be an excellent 60mm scope. It was my first spotting scope. I bought it in 1971 by mail from an ad in Audubon Magazine and I. still have it. The source was called "Danley's". In more recent years, I have purchased other Balscope Srs off eBay for student use on field trips. After a $100 overhaul, they will have years of useful life left even in student hands!

Good evening everyone,

I know this is a very old thread, but I have recently been looking for fixed eyepieces that fit my:
vintage Bushnell Spacemaster 2

After researching numerous sources, besides the old:
vintage (circa 1970's) Bushnell Spacemaster, Spacemaster 2, Trophy, Sentry, Sentry 2
Bausch & Lomb BALscope Sr.
Kowa TS-6
Opticron from the HR 60
Mead Research-Grade (after unscrewing the barrel)
maybe the Meopta (not 100% sure of these)
eyepieces, I've come across a contemporary solution.

Recently, I've purchased the:
Vixen GL series eyepieces
and they screw in just fine. The quality (please note I am NO expert) seems pretty comparable to the original:
#78-1120 - 20x
#78-1860 - 60x
Plus, better than my original:
#78-2209 - 20-45xZoom

They are also reasonably priced!
Vixen Eyepiece GL15
Vixen Eyepiece GL20 (Wide)
Vixen Eyepiece GL25 (Wide)
Vixen Eyepiece GL40 (Wide)
Vixen Eyepiece GL60 (Wide)
Vixen Eyepiece GLH20 (Wide)

Maybe I'm the only one left looking for vintage Bushnell Spacemaster 2 eyepieces, but I thought I'd post here on the off chance others are searching, too.

Everyone's Favorite Farm Animal,
