Na prijedlog kolege astronoma amatera Teofila predlazem otvaranje posebne teme o opcijama aluminizacije zrcala na evropskom prostoru. Firme, cijene, dostupne tehnike aluminiziranja itd...

Mislim da je bespredmetno stavljati cijene kada se mogu stalno mijenjati.

Ja bih kroz 1-2 godine obnovio sloj na 500tki pa gledam ove opcije:

https://www.taurustelescopes.com/en/telescopes/ ili kod proizvođača, Taurusa

Pa cijene bi bile pozeljne da se naravno moze kalkulirati koja opcija najbolje kome pase.

Zar je već tako rano potrebna aluminizacija na 500tki?

Promatram u uvjetima s puno peludi i visokom vlagom, svaki drek se lijepi na zrcalo. Čišećnjem neizbježno napravim male ogrebotine itd...
Nije strašno, ali će biti strašno u jednom trenu. Na GSO 300/1500 sloj je izdržao 7 godina, T500 imam 3 godine.

Ima li kvarcni sloj iznad ili ne ?

Ima, tj. ima SiO2, pretpostavljam da je to kvarc.
Problem mi je pelud, tu gdje promatram su livade pune trava i u zraku je hrpa tog smeća. Sjedne na zrcalo i zalijepi se. Zadnji put sam preagresivno krenuo na tu peludi napravio par ogrebotinica (1-2cm, hairline).
 Za sljedeće pranje zrcala ga mislim pustiti da se kvasi u posudi s toplom vodom i čarlijem par sati pa tek onda krenuti u pranje.

Jesi li siguran da tvoje zrcalo nije aluminizirano ion beam tehnologijom (IBAD) kao sto se to onomad moglo kod Atille u Veszpremu u Mađarskoj?

U tom slicaju su nanosi na zrcalu posve drugaciji, titan dioksid, tantal i niobdij pentoksid, aluminij itd...
