That link/ graphic doesn't seem to have come through. Pehaps you can edit it, Philip.

Plenty of clear blue skies at the moment, or at least that's the way it might appear. In fact there is a lot of haze which is giving low contrast images of Venus. This was the best I could do on the 7th April. Venus now proceeding the sun in the sky. The phase is getting larger but the size is shrinking. This was taken at 1315UT.Image

Hi Aratus I like the picture it is nice and clear,I would have trouble finding it myself during daylight as I have only a manual telescope.
Thanks

I don't need to tell you not to try, Andy, but for the sake of any others reading, I am able to find Venus by using a computerised mount which when aligned can find an object in the sky precisely and automatically. Manually trying to find an object in the sky, while the sun is up is asking for trouble. The slightest accidental glimpse of the sun through the telescope can seriously damage or destroy the sight in that eye.

When Venus is at its brightest it can be seen in the daylight sky. In the past I've been able to work out where Venus is and find it. The only problem is that you need to be looking directly at Venus to see it. Once you know where it is then you can place your telescope in the shadow of a building and then locate it through the telescope.

I'll happily keep posting photos here as Venus moves away from the sun in the sky, and changes from a thin crescent to a half phase. We've had some good views of Venus in the twilight sky for several years now, but unfortunately that won't happen again for 4 or 5 years.

A mixed day of cloud and sunshine meant I could at least try to get another shot of Venus. Some thin hazy cloud spoilt it again, but it wasn't as bad as recently.
Here is an image taken at 1047 UT this morning. A respectable 15% cresecent, but noticably smaller at 47 arcseconds.

Hi Aratus I like the image it seems a bit brighter round the edge.
Thanks

Venus is about 30 degrees away from the sun at the moment, so it is in a slighter 'darker' sky now. (If you can call any sky in the daytime 'dark'!) so the contrast with the sky is better. The sun angle is better too, so the planet limb is actually brighter than it was. I think it looks at its nicest at this time. The planet is still quite large, and I think chunky crescents look more impressive. :)

A bit of clear sky this morning, but being a Bank Holiday, it's bound not to last. Venus is now a 26% crescent, and quite a bit smaller, but still looking impressive. Venus is now nearly 40 degrees from the Sun. Image

5th May. A clear morning but the atmosphere wasn't very steady. Venus is now looking a little small at only 35 arc secs across. The crescent is 31%. It is very bright though. The image is not very good.

I did try to find Mercury, but it is lost in the glare of the sun at the moment.

Hi Aratus I like the image,hopefully the weather will improve as it always seems to be cloudy at the moment as I am hoping to get an image of M13.
Thanks
