I recently bought Dave Adshead's focal reducer for my 106 but it wouldn't focus when used with my M25C camera. And after a prolonged series of trials with different spacers etc., with a dealer of Takahashi telescopes, this is the final test on a faint area of nebulosity in Cepheus recorded in the second catalogue of Stewart Sharpless of "bright" nebulosity. It's also known as the Flying Bat, and is far more extensive than this frame of the brightest part. The FR gives the telescope a focal length of 387mm, but this bit of nebulosity would need a focal length of 150 to 250mm, so mosaicking or a camera lens would be the solution. But I've not enough patience for doing mosaics so I may try my old 135mm Pentax lens, some time in the future.
The night was cloudless but with haze, though the Milky Way could be seen all night. The dew was heavy too, and the car was wringing wet.
The exposure was 220 mins in total, and the guiding was done by my trusty H9C and Astroart. Stacked in Astroart and finally processed in Photoshop.
