~ Sunspot AR2765 heading toward western limb of the Sun ~

The sunspot is now looking very small in the 127mm refractor telescope as it rotates towards the western limb of the Sun on the 11th June 2020. During this afternoon observing session I was racing against time as cloud was coming all across the western sky.
 
After taking some images with the refractor I quickly removed it off the Pro HEQ5 mount and replaced it with the Lunt 60mm solar telescope to try and capture some images in Ha. (I always use this tracking mount when using both these telescopes)
 
It was really lucky to get a break in the cloud to capture just two AVI movie movies of the area with the Ha telescope before the whole sky clouded over and that was that…no more observing!
 
The white light image was taken with a 127mm refractor telescope that was fitted with a glass solar filter and using a Canon 700D camera.

​Just one image was captured with an exposure time of 1/320h second and ISO400.  The Ha image was taken with the Lunt solar telescope and a ZWO ASI120MC-S camera attached capturing an AVI movie file and stacking in RegiStax6 and processed in PS CS4.

~ Full Moon immersed in Belt of Venus ~
The late afternoon sky looked just so pretty with the colours of pink and blue in the eastern sky and the neatly full Moon rising between the bands.
 
If you look to the eastern sky after the sun has set you will see this astronomical phenomenon know as the Belt of Venus it’s also know as the Girdle of Venus too. This dusty pink band layered between the blue sky above and the lower deep blue-grey band below runs all along the horizon before sunrise or after sunset.
 
It’s related to our Earths shadow which extends millions of kilometres out into space, so next time you are watching a beautiful sunset take a moment to turn around and see if you can see this spectacular phenomenon low in the eastern sky.
 
I have just found this very interesting website called World of Phenomena that explains the ‘Belt of Venus’ very well along with a lot of other incredible phenomena that you’ll find in the world and up above:

The both images were taken with a Canon 70D camera and a Tamron 18-400mm lens on a tripod.

​The wide field image is cropped to a vertical image and the exposure time was 1/160th second with ISO400. With the lunar image the lens was set at 400mm with an exposure time of 1/250th second and ISO400, eight images were stacked in RegiStax6 and processed in PS CS4, image was also cropped.

It was quite late in the afternoon by the time I could finally take an image of this new sunspot on the surface of the Sun. I was having a lot of trouble trying to get some close detail on the sunspot and really could not understand why?
 
After packing up, I looked up towards Mt Tamborine and saw the reason why, a huge forest burn off was taking place and a large plume of smoke was spreading across the western sky. Because of where my telescope was setup between the two houses I was unable to see this smoke, Oh well, at least I was lucky enough to got some images of the sunspot even though they were a bit smoke affected :-)
 
My images were taken on the 5th June 2020, with a 10inch Schmidt-Cassegrain telescope that was fitted with a glass solar filter and using a ZWO ASI120MC-S camera with a focal reducer attached. The full disc image was taken with a Canon 700D camera, exposure time was 1/500th second and ISO200, 12 images were stacked in RegiStax6 and processed in PS CS4. The sunspot looked quite small on the full disc of the Sun.

This new sunspot is from the next Solar Cycle 25, please read more about this from

~ Huge Solar Halo in the sky ~
When I looked out my window late this morning, I saw this most amazing colourful ring right around the Sun. I flew downstairs, grabbed my camera and ran outside to capture it before it disappeared. I tried to block out some of the bright Sun with a wild grass plant that I found in the garden and it worked perfectly J
 
There is a lot of science behind one of these 22-degree halos around the Sun and for it to be displayed for us to see there has to be the right shape and size ice crystals in the sky. I’m always on the look out for them when this high cirrostratus cloud in covering the sky, you also can see a lunar halo when the Moon is in a larger phase…. so as I always say keep looking up, you never know what you’ll find!
 
To find out more please go to a couple of informative websites below:
Les Cowley, Atmospheric Optics website at:
https://www.atoptics.co.uk/halo/circular.htm
​
There is an excellent explanation and diagrams on how a Sun Halo is produced on the
WW2010 University of Illinois website at:
http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/opt/ice/halo/22.rxml

Image taken with a Canon G7x Mark11 on manual focus, with ISO125 and exposure time of 1/200th second.
(Be very careful not to look directly at the Sun, use your camera screen to safely compose the shot)
