I am a Japanese astrophotographer. Although my observatory is located in downtown Tokyo, I was able to capture deep sky images thanks to the great dynamic range of my 16-bit CCD camera and new image processing technology. Since 1990, most of these photos have been published in various astronomy magazines. These works were mainly taken using a 31cm (12 inch) Newtonian at home, but some were taken with a 20cm telescope (C8) carried to Australia and New Zealand. Nowadays, times have changed, and it is now possible to take pictures using telescopes located overseas using remote control. We started remote astronomical photography in 2023. The now widely known LRGB method was developed by myself and Robert Dalby in 1996. In agreement with Dalby, we named it "LRGB". Digital Development Processing (DDP) is also a technique I developed myself in 1995.
