這是AAVSO最近一位變星業餘目測觀測者的來函. 他和各位一樣也是住在一個充滿光害的底特律郊區.也觀測了一段時間想轉移到CCD的測光,然而學到許多測光和影像處理技巧後,最後想到剛進入愛看星星的初衷後,還是成為一位10"DOB反射鏡的快樂目測變星觀測者...

* 老灰阿看了一遍又一遍,覺得應該和各位鄉親分享他的心情...以下為原文內容...
I am a visual observer by choice. For years I struggled with a portable photometry setup, wheeling out a reasonably high end Goto setup (200mm reflector on Tak EM200, SBIG with UBVRI filters), but I found that many nights I would work until 2-3am just trying to get everything working in anticipation of a couple hours of photometric imaging before dawn. Completely frustrated, I decided to sell that setup and go completely visual until I can afford to setup a permanent observatory. I learned a good deal about photometric imaging and image reduction during that period which I am sure I can Leverage when I get back to it.
For now, I am enjoying visual variable star observing. Not only that, but I have gone eau naturale, replacing my old setup with a 10-inch dob and binoculars. I have assembled both a binocular and a telescopic variable star observing program and am becoming fairly adept at star hopping and visual observing, and am now working at increasing my tempo/productivity during observing sessions.
My question goes out to those experienced visual observers out there who also choose to star hop. What do you do during nights around a full moon, like tonight? Do you just pack it in, or do you have a strategy to remain productive in spite of the moon? I am already light pollution challenged here in suburban Detroit, but during moonlit nights find it difficult to star hop with much success. Your experiences and advice would be most appreciated.
Thanks -- Brian
