July 2019

July 14th 2215 GMT



The moon was waxing gibbous and its haze was obscuring nearly all of the stars. I took some snaps of the Moon, Jupiter and Saturn with my Mak and DSLR. I originally intended to use my Bresser Electronic Eyepiece but I was having problems re-installing software on my PC.

After some experimentation, I settled on 1,54m focal length, ISO 100 and 1/1000 second exposure.on the full lunar disc.

I then used a 3x Barlow lens to deliver a focal length of 4.62m and adjusted the exposure to 1/300 second. I did several imaging runs.





July 13th 2140 GMT



It had been cloudy for most of the day but it was almost clear near the Moon. Jupiter was nearby. Although I caught the two objects close together, I could not capture Jupiter's moons in the Moon's glare.

One of the early frames caught both.




This was the best of the Moon shots.



Jupiter showed quite well in later frames, so I combined one with the Moon shot, above, to produce this:



I had bad focus and Jupiter's moons were lost in our moon's glare. so that was the final image.

July 12th 2145 GMT


The sky was partially clear. I took some photos of the Moon at ISO 400 300mm focal length and 1/4000 second exposure.




I took some frames of Jupiter's moons at ISO 6400 300mm focal length and 1 second exposure.



July 8th 2100 GMT

I used the same settings as the evening before to snap the Moon.


July 7th 2100 GMT


The Moon was about four days past new and a few features were visible in its crescent phase.

I took a set of shots at 1.54m focal length, ISO 100 and 1/100 second exposure.




I took further sets of shots at 4.62m focal length, ISO 400 and 1/50 second exposure, after a lot of fiddling. Unfortunately, I didn't get focus.

July 7th 1500 GMT



The Sun was high and the Big Bear images showed a plage and some filaments. I did not see anything with my PST but took a few photos in the hope of detecting something.


July 5th 2030 GMT



I took some photos of the thin crescent moon at 300mm focal length, ISO 6400 and 1/4000 second.


July 3rd 2130 GMT



I snapped Jupiter's moons using the usual settings. As it was still twilight, I processed the image by removing the red and blue channels and enhanced the contrast. I caught some background stars.



July 1st 2310 GMT


There were several minor meteor showers active in the south eastern sky. I saw a faint meteor from one of the two Aquilid showers travelling north at about 3rd magnitude.

Photographic conditions started well enough but cloud spread from the north, ending the session prematurely. I took several series of frames at 16mm focal length, ISO 6400 and 6 seconds exposure. This was aimed primarily at meteor photography but I sometimes obtain some constellation shots as a by-product.

First was Aquila with Sagitta and Delphinus and at least part of Vulpecula.


The second photo also caught Sagitta but most of the area was covered by Cygnus. I caught Vulpecula and recognised the Coathanger.
