Welcome to my web site!

This version includes a special tribute to the massive sunspot, AR 2192, the largest for almost 24 years and one of
the top 30 or so in the past 140 years. Although imaging conditions were mostly rather tricky, it was an honour to be
able to see this beauty! I have also included a couple of images from Wales I took whilst on holiday and updated
sun (and 'sun pre 2012'), comets, aurora and deep sky galeries.

All of the images on this site are my own, taken using amateur telescopes and equipment.

As ever, I hope this encourages you to get out there and enjoy the treasures of our universe at first hand.

Best Wishes,  

Peter Garbett

The story of a great sunspot, AR 2192

In October 2014 we were treated to the spectacle of the largest group of sunspots for almost 24 years.
At its peak, it attained an area of 2750 micro hemispheres.



An amazing stroke of luck!

Having seen on SapceWeather.com that an X2 flare was in progress, I rushed to image the
event, despite the Sun being very low and about the vanish behind nearby houses. As I took
my first video sequence, an aircraft passed straight through the field of view, amazingly
crossing right through the lasso shape formed by the X2 flare!

AR 2192 had an area of 2750 micro hemispheres at 0h and 2380 by 24h today.
By oh on 29th it had grown once again to 2680. It will be interesting to see what it
is like on its next rotation.

Just 19s of video captured (720 frames), histogram only 47%! A bit 'noisy' but worth the panic! Extremely challenging
imaging conditions in chinks between clouds and through partial cloud! AR 2192 had an area of 2700 micro hemispheres
at 0h and 2740 at 24h today.

Very tricky imaging conditions, with the remnants of ex-hurricane Gonzalo over us.

Wales: August 2014



IC 1396
The large red nebulosity right of centre is IC 1396, with Herschel's red 'garnet star' sitting on top of it. The red patch far left of centre is Sh2-132.
The dark nebulae upper centre are B169-71 and the bright bluish white star upper left is Delta Cephei, the prototype Cepheid Variable. The other
bright reddish star is Zeta Cephei with red emission nebulosity Ced 199 extending above it.

Altair and central Aquila
Notice the 'E' shaped dark nebulosity upper right (near the star Tarazed). This is the 'Triple Cave Nebula', fittingly attributed to E.E.Barnard!!!
