Welcome to my web site!

This version includes new images of The Whirlpool Galaxy (M51), Jupiter, Venus, the Sun and the crescent Moon.

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

R(G)B for detail plus RGB for colour
The rotated version helps me notice the colour variations between the belts as one moves from left to right and also
accentuates the non-spherical nature of this rapidly spinning gas giant.

The solar eclipse of 20th March 2015

This was a beautiful eclipse, made all the more atmospheric by the ever changing clouds.

All of the images taken whilst teaching using a modified Canon EOS 450D DSLR, 300mm lens @ F32 and
Baader Astrosolar film when necessary.




The crescent Moon and Venus two days after the solar eclipse


  





Just as with the solar eclipse I used my Canon EOS 450D with a 300mm lens.









The Moon on 30th January 2015


Clavius




   

Philolaus (upper left)
One of its central twin peaks, just catching the sunlight.













Anaxagoras is the prominent crater lower left, with the less well defined
Goldschmidt and Barrow to its right.
Notice the rays apparently coming from Anaxagoras.





Bullialdus (upper right)
Notice the three arcuate rilles that lie just outside the dark form of Mare Humorum but may
be associated with it.








The Crescent Moon on 21st May 2015

Poor seeing at low altitude, but imaged nevertheless because of the interesting features present.






























Various images of a 1 million km long dark filament on the Sun

Beautiful nebulae in Auriga


 


(Lower) IC405 'The Flaming Star Nebula' with  the 'runaway star' AE Aurigae embedded in it.
(Upper) IC410 and open cluster NGC1893
The three 'bright' stars near centre are 19 Aur (mag. 5.05), IQ Aur (mag. 5.35) and 16 Aur (mag. 4.50).





The images above were obtained on the nights of 19/20 December 2014 and 24/25 December 2014.
Telescope: 80mm Megrez apo refractor with x0.8 focal reducer giving F4.8.
Camera: SXVR-H18 CCD at -30C. Filters: Baader 7nm H-alpha 4h 15m of data made of 17 x 15 min subs;
Baader 8.5 nm OIII 4h 30m of data made of 18 x 15 min subs. The final image was an H-Alpha:OIII:OIII combination.




Orion, the hunter



Barnard's loop shows up well as does the diminuitive Horsehead Nebula. Very surprisingly, the Witch Head
nebula is vaery faintly visible to the right of Rigel (lower right). This all despite having to contend with
significant extra light pollution due to the ultra invasive site lighting where Network Rail are locally upgrading
bridges for electrification of the line. Additionally, I cold not reach focus with the CLS filter in place so had to
improvise and crudely blu tack it to the front of the lens, losing about a quarter of the light due to
obscuration by the filter! No flats, bias or darks used!
Canon EOS 450D; Astronomik CLS-CCD filter; 13 x 8 mins plus 5 x 2 mins from the night of the Geminids used
to show the Orion Nebula without it being 'blown out'.



Closer look at the Horsehead.







M33, the Triangulum Galaxy


The image above were obtained on the nights of 24 November 2014, 13/14 December 2014 and 19/20 December 2014.
Telescope: 80mm Megrez apo refractor with x0.8 focal reducer giving F4.8.
Camera: SXVR-H18 CCD at -30C. Filters: Baader UV/IR rejection filter with Trutek Type 1 L, R, G and B filters.
LRGB: L = 6h 45m in 15 min subs; R = 6 x 10 mins 2x2 binned, G = 7 x 10 mins 2x2 binned, B = 6 x 10 mins 2x2 binned.





Luminance data only.


Below are slightly differently processed versions that emphasise different aspects of M33.








A nice dsiplay of the Geminids
13-14 December 2014




A 2nd magnitude Geminid streaked by the Orion Nebula. I saw it visually and luckily it was caught
with my Canon EOS 450D.
