Altundeva ,unde sunt oameni obisnuiti ,nu oameni mari si oameni mici ca pe ulitele forumului nostru,undeva unde sunt amatori care construiesc sau cumpara cu precadere lunete,acolo asadar predomina parerea ca o montura buna pentru o luneta cu focal de un metru nu este usor de construit;iar pentru o luneta cu focal de peste 1,5 metri este chiar dificil.Dar ma rog,pe langa faptul ca oamenii aceia sunt si nitel mai inapoiati,cum tocmai s-a explicat aici,familiarizati cu Unitron,Towa,Mayflower,Jaeger,Carton,Saers,Zeiss si alte d'astea (numai de pe alte meleaguri,nimic mioritic),dumnealor nici nu beneficiaza de savantii pe care-i avem noi,ca sa nu mai vorbim de oamenii mari cu care suntem binecuvantati noi,pigmeii de pe aici.
Iata mai jos descrierea unor observatii facute de unul din aceia,cu o prapadita de luneta de 63mm.De data aceasta fara diafragmare,am verificat textul ,sa nu mai enervez pe nimeni.In privinta distantei dintre granita noastra si Danemarka ,inca nu am reusit sa fac nimic.Lectura placuta,micutilor!Mircea

Hi Edwin

I have seen too many objects, that most observers consider "impossible" in a small scope, to remember them all. A few do stand out in my memory, however.

First and foremost must be my observations of G1 (also known as Mayall II), the brightest globular cluster in M31 and the brightest globular in the local galaxy cluster. I have seen it several times in my 63mm Zeiss Telemator. It is roughly mag 13.5, when you include the two mag 14 field stars right next to it, which I couldn't resolve. The cluster alone is mag 13.7. Many people report of having huge difficulties in finding it, even in large scopes, but that is because they don't have an accurate map. The field is easy enough to find a few degrees from M31 and the globular easy in my 5" refractor, where it is clearly visible as a small fuzz, much like NGC 6229 in a 50mm binocular. 

Another is Minkowski 1-64, a planetary nebula in Lyra. It is roughly mag 14, though I suspect that to be a photographic magnitude and that it must be at least a magnitude brighter in visual. 

Then there's the Draco Triplet, a triplet of galaxies in Draco, one of which is a mag 13.1 edge-on. It was extremely difficult, but I spotted it one superb evening. The other two are mag 11 or so, bright and easy to see. 

NGC 4486B is a companion to M87. It is a dwarf spherodial galaxy, just like M32 and roughly of the same physical size and surface brightness, but of course much more distant and thus around mag 13.5. Still, it is possible to see it in my 63mm Zeiss. M87 has four other companions that are a challenge in a 60mm. 

Surely, UGC 11465, a mag 11 galaxy a few arcminutes north of 16 Cygni, also belongs on this list. I had to use 84x and place 16 Cygni outside the field, but then I could hold the galaxy a few seconds each time. Yes, you can see UGC galaxies in a 60mm, although only a few!

Then there are the number of PK planetaries I've hunted down with homemade maps, made from Palomar Survey images, as well as the large number of more or less anonymous galaxies. The list goes on and on. Minkowski 1-92 "The Footprint Nebula", IRAS 09371+1212 "Frosty Leo", Markarian 501, Berkeley 10, IC 289, IC 1747, the list goes on and on....

I have probably forgot many.

Clear skies!
