Don’t despair - most inexpensive 60mm (2.4-inch) refractors can be rendered much more useful with the expenditure of some time and a little money.作者: Tortuous 時間: 2025-3-22 18:48 作者: FLEET 時間: 2025-3-23 00:18
,Diskussion nach den Beitr?gen , und ,It is probably my imagination, but for years it has seemed to me that most of the really active meteor showers reach their maximum when the Moon is unfavourable, the Sun is above the horizon, or the sky is overcast. But since I began to observe these showers with a small radio telescope, these unfavourable conditions have mattered little to me.作者: licence 時間: 2025-3-23 03:00 作者: 熄滅 時間: 2025-3-23 09:04
The “C5++”..The Celestron C5 optical tube assembly (OTA) has been in production since 1971. Since then, the telescope has come in a number of different varieties, with various mounts and accessory options as standard.
