兩台等了一年多才交付的Celestron名鏡，今日終於抵港，很快便會投入運作。
Celestron RASA 36 是口徑355mm f/2.2，焦距790mm的攝星鏡，成像圈達60mm。
Celestron EdgeHD 14 是口徑355mm f/11，焦距3910mm的目視及攝影鏡，可以用原生f/11、減焦鏡後的f/7或配合Hyperstar後的f/2拍攝 https://eshop.astro.hk/hk/catalogs/lists?sfor=default&sfna=Hyperstar。今天收到後特別以專用器材以1000倍檢測，確定光學修正度一如理想。

The two Celestron telescopes which have been waiting for more than a year are finally delivered today and will be put into operation soon.
The Celestron RASA 36 is a 355mm f/2.2 astrophotograph with a 790mm focal length and a 60mm image circle.
The Celestron EdgeHD 14 is a 355mm f/11 visual and photographic telescopes with a focal length of 3910mm. It can be used to shoot at native f/11, f/7 with a reducer, or f/2 with Hyperstar https://eshop.astro.hk/hk/catalogs/lists?sfor=default&sfna=Hyperstar . After I received it today, I specially tested it at 1000x magnifications with special equipment to confirm that the optical correction is as ideal.
