June 2018

June 21st 0940 GMT


As the Big Bear images were showing sunspots, I took some full disc shots with my Mak and DSLR. Focal length was 1.54m, ISO 100 and 1/4000 second exposure.



I followed on with some full disc shots of the Sun in hydrogen alpha light.


June 20th 1920 GMT


Cloud had been moving backwards and forwards across the Moon for over half an hour. It finally cleared and I took some full disc frames of it. I used 1.54m focal length, ISO 100 and 1/500 second exposure.




June 15th 2300 GMT

I took some frames of Jupiter with its moons with my DSLR at the usual settings.


June 14th 1225 GMT

I started off with the wrong eyepiece but proceeded to take some shots anyway. I changed to the right one and took some full disc shots that showed some activity. I processed the best full disc shot first.


Some of the close-ups with the wrong eyepiece showed some interesting detail.


June 12th 2200 GMT


I took my DSLR and Mak out for a quick shoot before bedtime. It would have been better to use my Meade Electronic Eyepiece but I did not want a long session, as I had work the next day.

I snapped Venus at 1.54m focal length, ISO 100 and 1/200 second exposure.



I tried a slightly longer exposure of 1/100 second for Jupiter. It didn't work, as I didn't catch the cloud belts.

I tried a longer exposure of 2/3 second and ISO 6400 in an attempt to capture Jupiter’s moons. I liked the result.




June 11th 1535 GMT

I took a few frames of the Sun in hydrogen alpha light and found some activity.


June 10th 0000 GMT


I photographed Jupiter’s moons with my DSLR at the usual settings.




June 9th 0620 GMT


The Sun was low and conditions were hazy but I snapped the Sun in hydrogen alpha light with my PST, as the weather forecast for later was thick cloud.



I processed another frame later.




June 6th 0920 GMT


The Sun appeared slightly more active in hydrogen alpha light.




June 3rd 0935 GMT

I checked the Sun in hydrogen alpha light. Although it was quiet, I saw some albedo features.


June 2nd 2230 GMT


It was not a fantastically clear night but I went out, as I did not have work the next day. I started off with the camera at 300mm focal length, ISO 6400 and 2 seconds exposure. My targets were Jupiter and the area around Antares.

The Jupiter shot was slightly out of focus but showed the moons and background sky well.


The Antares shot suggested some background Milky Way stars.




I then adjusted the camera to 70mm focal length, ISO6400 and 8 seconds exposure. Targets were Albireo, the centre of the cross in Cygnus, Cassiopeia and another go at Antares.

Albireo was near the top of the frame.


Central Cygnus caught M29.


Cassiopeia turned out well, despite the conditions.


The Antares shot was swamped with cloud.

June 2nd 1640 GMT


The Sun seemed quiet in hydrogen alpha light.

May 2018

May 27th 2130 GMT

Jupiter and the Moon were close. I took some frames at various ISO settings and exposure times at 300mm focal length to try to capture the most detail.

First, I took the two objects together.


Then I caught the Moon on its own.


Then I caught Jupiter's moons and had a tough job removing the glare of the Moon.


Unfortunately, I was unable to remove the lunar glare, so this had to be the final result.



May 27th 1345 GMT


After an unsuccessful attempt earlier, I managed to photograph a quiet sun in hydrogen alpha light.
 
 

May 25th

I took some snaps of the Moon with my DSLR before bedtime.



May 23rd 1055 GMT


 
After a cloudy start, it cleared to show the Sun. I was not sure whether I could make out a solar prominence on the bottom limb or not. I took some full disc shots in hydrogen alpha light. There was some sign of activity in the photo.


May 22nd 2135 GMT

I took a few frames of the Moon with my DSLR at 300mm focal length, ISO 100 and 1/1000 second exposure.


May 21st 2030 GMT

Conditions were not perfect, with lots of moving cloud but it had seemed a long time since  had used my Mak and DSLR to photograph the Moon. I took 38 frames at 1.54m focal length, ISO 100 and 1/100 second exposure.


 


May 19th 2230 GMT


It was dark but there was a lot o haze scattering the moonlight. I took some light and dark frames of Jupiter with its moons.
 
 

May 19th 2125 GMT


The Moon was just about to disappear behind a tree, so I took some full disc shots at 300mm focal length, ISO 100 and 1/500 second exposure.
 
 

May 19th 0900 GMT

Again, the Sun was quiet but I managed to find some detail in hydrogen alpha light.



May 18th 0715 GMT


The Sun seemed quiet and I could not see any more detail by tuning the etalon. Unfortunately, I did not capture any decent shots.

May 17th 2035 GMT


I was out and about and knew I would not be home before the Moon set. I took a photo of it with Venus with my phone camera.
 
 


May 17th 0830 GMT


I could see some granulation on the Sun in hydrogen alpha light but no features.
 
 


May 16th 2150 GMT


I tried to photograph Jupiter with its moons with my DSLR at 300mm focal length, ISO 6400 and 2 seconds exposure. I found that there was lots of haze around Jupiter, so I tried some shorter exposures to see what would happen. I removed some but not all of the haze.

 


I also tried a few shots of the Beehive (M44) and missed totally but caught a few Cancer stars and thought I might have caught M67.

 


May 15th 0645 GMT


It was clear but the Sun seemed quiet. I took a few full disc shots.
 
 
 

May 13th 0940 GMT


I could see some granulation on the solar disc in hydrogen alpha light.
 
 

May 7th 1440 GMT


I could see some shading near the solar limbs but the Sun was quiet, otherwise.



May 6th 0930 GMT


It was warm and sunny. I did a hydrogen alpha shoot with my DSLR and PST. The sun appeared quiet in the eyepiece but I could see some granulation in the camera viewfinder.
 
 

May 5th 2220 GMT


I set up the camera at 70mm focal length, ISO 6400 and 7 seconds exposure and took several frames of Lyra. I took 74 light frames and 18 dark frames.

 


While waiting, I had a session with the review binoculars. By the end, my arms were nearly dropping off, as they are quite heavy. At least I had a great session. I started off with Jupiter and I used it to adjust focus. The planet showed a small amount of red fringing but it was much more sharp than I had ever seen through binoculars and I could see all four Galilean moons, even though two were very close to the planetary disc. Lyra was about 20 degrees above the horizon. Epsilon  split easily into two stars and so did Delta. Despite the low elevation, I was able to see the Ring Nebula (M57), usually a tough target for binoculars of this size (15x70). I was able to see the Leo Triplet (of galaxies), which contain the spiral galaxies M65 and M66, plus a slightly fainter galaxy whose name I forgot!

 

This encouraged me to have a go at the Virgo cluster and I identified four fuzzy patches of light that were clearly neither comets nor stars, so must have been galaxies. I was able to pot the globular star clusters M13 and M92 in Hercules and M3 in Canes Venactici. I also saw the galaxy M51 there, plus M81 and M82 in Ursa Major. I tried to find the global star cluster M5 in Serpens but my arms were too tired.

 

After a short rest, I could not resist the temptation to look at the Beehive Cluster (M44) and Melotte 111, even though I had seen them a few days before. They looked so good, I did not regret a second visit.

 

I moved the camera to aim for the Beehive cluster but I could not make out in the viewfinder whether I had caught it or not. No I didn't but there were lots of stars east of Cancer.

I caught a meteor a few degrees east of the Beehive.


 

I changed to 300mm focal length and 2 seconds exposure on Jupiter then took some dark frames.
 
 

May 5th 0810 GMT

The Sun was quiet in hydrogen alpha light. While I was tuning my etalon, I saw an aeroplane fly across the solar disc and leave a vapour trail.


May 3rd 0750 GMT

The Sun was quiet but I had a go at photographing it in hydrogen alpha light anyway.


May 2nd 2130 GMT

I missed the Sun because of work. I wanted to snap Leo, as I did not have a good shot of it. I took some photos with my old Konica Minolta at 18mm, ISO 800 and 30 seconds exposure. Unfortunately, I was unable to extract the photos from the camera. 

I then took 2 sets of shots of Leo with my Nikon at 70mm, ISO 6400 and 8 seconds exposure.
 
While checking the images, I found a sporadic meteor near Regulus. By checking the preceding and following image captures, I knew that it was not a satellite trail.
 
 
Now for the first Leo shot.
 
 
 
... and the second.
