Apr 1st

I was limited to a quick photo shoot of the Hyades and Pleaides by general busyness but was quite pleased with the results.



Apr 2nd

Conditions were hazy with bright moonlight. I took a few snaps of the Moon but, although I could see some surface features on Saturn, photographing it was another matter.



Well at least you can make out the rings! The Moon shots were more promising.




Apr 4th

I went out for a solar photo shoot at 11:00 GMT. Although the solar surface looked bland at first, I could see a nice prominence in the lower left quadrant.



Apr 5th

It was the time of year that made astronomical blogging difficult. It was after midnight when I went out but, technically it was 23:30 GMT! The plan was to take some quick Moon shots followed by an attempt on the Virgo supercluster. The Moon was gibbous and about 8 days "old".



Then it was down to the real business. I started off with M53 that looked like a globular cluster but there was no real detail discernable. The Black Eye Galaxy (M64) didn't show its full glory in my Mak but at least it looked like a spiral galaxy. I then moved on to the M98/M99/M100 trio. Only M100 actually appeared as a spiral but at least I'd already bagged 5 Messier objects I'd never seen before. Next, it was the difficult task of going to Gamma Virginis, the bottom of the Virgo bowl and working my way up. As predicted by the star atlas, it was M87, M49 and M60 that stood out as the brightest and biggest galaxies. Some of the galaxies showed their nature as being elliptical or spiral but, in general, anything fainter than about magnitude 9.2 appeared as no more trhan fuzzy patches. I even got lost navigating at times, as I could even see some NGC members that weren't on Messier's list, although I did not explore them, as the urgency was to map the Messier objects in the Virgo supercluster for an upcoming book. Even so, it took a full 90 minutes before I could tick all of the Messier galaxies off of the list.

Due to the Sun only being visible during mealtimes, etc, I missed it and evening conditions really allowed viewing of one object only - the Moon. I went out at 20:30 to do another shoot.

  

Apr 7th

I went out with the PST and also tried adding a light pollution to the system, which seemed to reduce the bandpass a bit.



April 11th

I went out with the PST at 14:00 GMT. The Sun was covered by thin cloud but I was able to see some shading on the solar disc.



Apr 12th

It had been a frustratingly cloudy evening, which was supposed to be clear. I had hoped to do some constellation shots plus some Messierising. However, there was lots of cloud about, some rather thick. I was able to see the Beehive (M44) through cloud and (less surprisingly) Melotte 111. I split Mizar/Alcor and Epsilon and Delta Lyrae. I could also see Saturn's rings edge-on. The Moon was low and gibbous and partially obscured but Tycho and its rays were dominating the lunar landscape.

Well it finally cleared at 01:00 GMT, although not enough for me to have another look at the Virgo galaxy cluster. Wanting to take some constellation shots of the area, I took snaps of Virgo and Coma Berenices with each of 2 cameras. I decided to post the shots with each, as I felt each had something to offer.





I built new solar filters for my binoculars and bin scanned the Sun through thin cloud at 11:40 GMT. As expected, I didn't see any sunspots.

At 22:50 GMT, I did a bin scan. Conditions were poor, with lots of haze around the horizon. Mizar and Alcor split but I could find no sign of M81 or M82. Melotte 111 showed quite well and so did the main asterism of the Beehive (M44). Nothing else was visible, except Saturn's rings.

April 13th

Bin scanned the Sun at 09:40 GMT in a clear sky.  The view looked much sharper in my new filters but, unfortunately, there were no visible sunspots. I then did a hydrogen alpha shoot and noticed a nice prominence and a faint filament.



Out of the close-ups only the prominences came out.



Apr 18th

 
Bin scanned the Sun at 16:50 GMT with my new filters and the Sun looked really clear, with limb darkening very clear but there were no sunspots. I went out again at 22:00 GMT with the Mak to do some Messierising. I was out for a full 90 minutes, so the session (technically) ended on 19th. The first stop was the Beehive (M44) and the light pollution reduction (LPR) filter did its job very well and it looked really clear. I found the Sombrero galaxy (M104), with some difficulty, and it showed some structure but not as good as the classic photo. M68, the globular cluster in Hydra was barely visible.

At about 22:13 GMT, I  noticed a sproadic meteor of 2nd magnitude flash south through Auriga.

I revisited M59 and M60 (Virgo supercluster members) and M60's elliptical structure was more obvious with the LPR filter. The next target was M3, which was disappointing. I found it hard to find and had to sweep it with the bins first. Although it was an obvious globular cluster, it didn't appear much better in the Mak. I revisited M53, not being quite so sure about it as on the last visit and found some hint of structure with the LPR.

I uncovered M94 and M63 in Cannes Venacti and M63 was the better of the two, actually appearing as a proper spiral. While finding them, I used Cor Caroli as a signpost and was amazed to see it split into a double at only 24x magnification.

I revisited M51 and was pleased to see that the nearby
NGC5195 came more into prominence. I  didn't remember visiting M101 before but, reviewing my records, noted that I hadn't seen ist spiral arms. This time, they were visible and it was amazing how large the galaxy is. I had my first views of M109, M108 and M97 but these were just fuzzy patches. However, the total of 11 Messier objects wasn't bad and great progress towards my next book.


April 19th

 I took a look at the Sun through my PST at 10:50 GMT. It was very quiet, with no prominences but there was a small filament visible. Only two of the close-ups came out but the surface detail was quite good.

  

April 21st

I attempted a PST photo shoot at 12:10 GMT and, although I could see some small surface features, they failed to photograph.

April 22nd

Bin scanned the Sun at 18:00 through thin moving cloud but didn't see any sunspots.

April 24th

I .bin scanned the Sun at 16:55 GMT but didn't see any sunspots.

April 25th

I did a hydrogen alpha shoot at 14:30 GMT. A small prominence was visible at the lower part of the Sun but it only came out in one photo.




At 20:35 GMT, I saw Mercury with the unaided eye but cloud moved over before I could mobilise my telescope.

I returned out at 21:00 GMT. There was some cloud but it was moving. Although there were lots of objects to choose from, I concentrated on getting a position photo of M68 and a snap of the Beehive (M44) to support some publishing work. Unfortunately, the Corvus shot was rather north of M68 but Virgo came out well, with Arcturus and Saturn sneaking into the picture.



While attempting the Beehive, I saw a faint satellite. I did 25 attempts and this was the best.



I was out again at 22:15 GMT, as I'd missed the southern part of Virgo and Corvus but this time, I bagged it.



April 26th

It was still clear when after midnight GMT (despite the forecast). Time was ripe for an assault on some globular clusters. However, the first task was to get the position photos and I was pleased to record the faint constellation of Serpens Caput.



I also snapped Hercules to plot the positions of M13 and M92.



The final session of the night was when I returned with the Mak armed with the 32mm Plossl, focal reducer and light pollution filter. M13 was really memorable and was my best ever view of it, even with larger instruments. M92 was somewhat of a disappointment but M5 was nice, showing obvious structure and a very pronounced core.

Except it wasn't the final session as I went out again at 02:00 GMT to snap a couple of more constellations. First up was Scorpius and Ophiuchus.



Cassiopeia was low but I still managed a nice shot.



April 28th

I bin scanned the Sun through thin cloud at 17:45 GMT but didn't see any sunspots.

April 29th

Solar viewing conditions had inmproved somewhat since the day before when I bin scanned the Sun at 15:15 GMT. I could see limb darkening very clearly but didn't see any sunspots.

I did a hydrogen alpha photo shoot at 16:50 GMT. Conditions were hazy but I managed to see some surface detail and a curious bright spot. A prominence turned up in the photos, which I'd missed visually.
