An-eagla a bhí orm go ndéanfar damáiste do bhraiteoir mo cheamara agus mé ag déanamh an ghrianghraif. Ach tá sé fós beo, baochas le dia. Tá fócas beagán shite toisc ná raibh uaim súcradh leis an gceamara ró-fhada agus é dírithe i dtreo na gréine.

My brother lent me an old ЗМ-5А (ZM-5A) 500 mm f/8 mirror lens and a 2× teleconverter.

This is the result of me playing with it yesterday. :) Five stacked exposures at 1/20 s each, ISO 640 each.

Effective focal length 1000 mm, equivalent of 2000 mm full-frame.

The lens is pretty much a compact Maksutov-Cassegrain telescope with m42x1 mount.
