Coronado ST 70/400 SolarMax III aurinkokaukoputki 10mm estosuodatin <0.5Å Double Stack
Hinta 3 942,00 €
0.5 ångströmin kaistanleveys. Double stack eli kahden etusuodattimen (etalonin) malli.
Tämä malli sisältää kaksi edessä olevaa etalon-suodatinta. Kuva on tummempi, ja pinnan yksityiskohdat näkyvät entistä paremmin. Double stack parantaa erityisesti kontrastia. Toinen etalon-suodatin voidaan tarvittaessa ottaa pois, jolloin kaukoputken kaistanleveys on 0.7 ånströmiä ja kuva on aavistuksen valoisampi.
Coronadon uudistettu Solarmax III mallisto tarjoaa paremman 2-nopeuksisen crayford tarkentimen (rack & pinion), modulaarisen rakenteen jonka ansiosta aurinkokaukoputki on muokattavissa myös tähtikaukoputkeksi. Tähtikaukoputkena apertuuri on 70 mm, aurinkokaukoputkena suodattimen johdosta apertuuri on 60 mm. Sopii aloittelijoille ja edistyneemmille auringon havaitsemiseen ja valokuvaukseen innostuneille.
Aurinkokaukoputki on suunniteltu toimimaan vetyalfan aallonpituudella 652.8 nanometria. Kuva on tummanpunainen visuaalisesti tarkastellen. Erityisen näyttäviä kuvia syntyy monokameralla, jolla saa esiin erilaisia auringon pinnan yksityiskohtia kuten auringonpilkkuja, aktiivisia alueita ja pinnan kromosfääriä. Kaukoputken edessä olevaa etalonia eli suodatinta säätämällä voi hienosäätää yksityiskohtien näkymistä joko pinnan kromosfäärissä tai reunojen protuberansseja eli kaasupurkauksia. Protuberanssit saattavat olla hyvinkin lyhytikäisiä toisin kuin auringonpilkut, jotka voivat kestää päiviä tai useita viikkoja.
Auringon pinta voi olla ajottain ilman sen suurempia piirteitä, erityisesti auringon aktiivisuuden minimin aikaan. Toisin kuin white light havainnot, vetyalfa tarjoaa lähes tulkoon aina jotain nähtävää. Silmää on hyvä myös totuttaa tumman punaisen valon havaitsemiseen päiväaikaan.
Muista aina tähtikaukoputkena käytettäessä kiinnittää etusuodatin ja estosuodatin paikoilleen, ennen kuin kaukoputkella taas tarkastellaan aurinkoa.
