July 2018

July 15th 1030 GMT


The Sun was quiet again, even in hydrogen alpha light.



July 15th 2330 GMT

I recovered a bit but decided to have a session with the camera alone, in case I felt queasy again. I used the DSLR at 70mm focal length, ISO 6400 and 8 seconds exposure.

First, I took a few frames of Aquila to see if I could stack some shots.

My next target was Sagitta.

I didn't get either but I did get the Coathanger and its surroundings.


I used Microsoft ICE to stack part of the constellation.




Although it was low in the sky, I tried Triangulum.





I then increased the focal length to 300mm and reduced the exposure time to 2 seconds. I tried Melotte 20 and the Perseus Double Cluster.




July 14th 2200 GMT


I had a few more problems with the Meade Electronic Eyepiece. I took a few shots of Jupiter with my Mak and DSLR using various exposure times and focal lengths up to 9 metres. I caught some nice frames of the moons. I was going to image Saturn but could not, as I was feeling unwell.



July 14th 0730 GMT


Despite carefully re-tuning my etalon, the solar disc seemed very bland and quiet.



July 11th 1015 GMT


The Sun seemed much quieter than the day before.



July 10th 0650 GMT

The professional observatories showed some faculae rotating onto the solar disc. They were difficult to make out in hydrogen alpha light.


July 9th 1410 GMT


The sky cleared for a while to a sun quiet in hydrogen alpha light.




July 8th 2130 GMT

I took some shots of Jupiter with my DSLR in an attempt to capture its moons. The initial frames seemed over-exposed, so I reduced the exposure time.


July 8th 1400 GMT

The Sun seemed rather quiet and I took some full disc shots.


July 8th 2345 GMT


I waited for it to get as dark as it gets but possibly waited a bit too long, as Jupiter was close to setting. I used my Mak and DSLR in an attempt to capture Jupiter’s moons and Titan around Saturn. I used 1.54m focal length, ISO 6400 and 2/3 second exposure.

The focus wasn't great but I caught all five moons.




I attempted to repeat the same settings with the Andromeda Galaxy (M31) and Melotte 20. It didn't work on M31 and the Melotte 20 shots just showed Alpha Persei.


I finished by taking the DSLR out on its own with 70mm focal length, ISO 6400 and 8 seconds exposure. My targets were the small constellations Corona Borealis and Delphinus.

Result!



July 7th 1800 GMT


The Sun looked quiet in hydrogen alpha light, even quieter than the day before.




July 6th 2225 GMT


I took some frames of Jupiter and Saturn with my DSLR in the hope of capturing some moons.




July 6th 0700 GMT


The last quarter moon was quite high just past south. I took some snaps with my DSLR at 300mm.




The Sun looked quiet in hydrogen alpha light and I took some full disc frames.


July 1st 2300 GMT


It was my first session of a new month and I started with my Mak and DSLR on the Moon.




To be honest, I did not adjust the ISO setting when I should have, so some shots were wasted, especially the ones of Jupiter’s moons. I had a go at Jupiter, Saturn and Mars with the same set-up but more in hope than expectancy.

The shots of Jupiter's disc were fuzzy but the result with the moons was not bad,


I caught Saturn's rings but little else.


Mars showed very little.



I took a few frames of the Moon with Mars. With a bit of digital wizardry, I combined one of them with the individual images of the Moon and Mars.



I changed the set-up to the DSLR at 70mm ISO 6400 and 8 seconds exposure to . With moonlight, it was not a good night for constellation or deep sky photography but I went for Cassiopeia, the Andromeda Galaxy (M31), Melotte 20 and the Perseus Double Cluster. The Double Cluster shot did not work but the other three did.




I then tried to capture Titan and Jupiter’s moons with 300mm focal length.

I caught Saturn with Titan.



... and another shot of Jupiter's moons.
