Campanula medium – Pink Bell flower

My wife recently received a big bunch of flowers from a colleague. There was one particular flower which caught my eye – it looked like a pink bell and the internal structures holding the pollen was what drew me to it. Hence I knew I had to take photos of it, and in particular macro photos of the pollen. Continue reading Campanula medium – Pink Bell flower

ZWO ASI1600MM-cool – UV imaging

One other thing I was interested to test out on the ASI1600MM-cool is its UV-imaging potential. This could be particularly useful bearing in mind its slightly larger sensor, for documenting the UV-pattern of flowers or of the human skin (bruises, sun-damage etc). I picked a Buttercup flower from my back garden and used this as my subject for testing its UV-imaging capability. Continue reading ZWO ASI1600MM-cool – UV imaging

ZWO ASI178MM-cooled – UV imaging (part 2)

Having tested the ZWO ASI178MM-cooled for UV imaging, and found that it is very capable for such invisible band imaging, I decided to take it to the next level of testing to see what are the limits to its capabilities. My subject is the more well known Dandelion flower which I had picked from my back garden. This flower has been imaged many times in UV, so it is sort of a reference flower for UV imaging.

ZWO ASI178MM-cooled UV-imaging

One of the areas of photography that I have an interest in, and wanted to test out of the ASI178MM-cooled for a while, is UV-imaging. That is imaging below 400nm wavelength, which is  invisible to normal human vision. Now it is unclear the response of the IMX178 Sony Starvis sensor to the light below 400nm, but I felt I needed to test this out, particularly as it does not have a Bayer Matrix to affect UV-transmission. But the big question I had was whether the AR window protecting the sensor would block deeper UV? Continue reading ZWO ASI178MM-cooled UV-imaging

My DIY Solar finder

Previously when imaging the sun with the Baader Herschel Wedge, it was very easy to locate the sun as there was a window on the wedge to identify where the sun was. But with the purchase of the Daystar Quark, I needed another way of locating the sun. I did consider buying the Televue Sol Searcher, but since I had to order and wait for it to arrive, I decided to try my hand at DIY with what I had. Continue reading My DIY Solar finder
