Mark PhillipsThis site was originally my PhotoBlog, but I have now changed it to be my astronomy website. It’s called ForthImage as I originally did a lot of my photography around the River Forth, the river on which the city of Edinburgh stands. It’s a place where I can post my images purely for the fun of it! Feel free to: ahhhhh with delight (unlikely), snigger with derision (likely), or offer (de-)constructive criticism (welcome).

See dark matter masquerading as dust on my camera sensor; marvel at the weird and other-worldly effects of my feeble attempts at image processing; hoot with laughter at gravity winning yet again as I drop an expensive eyepiece on the observatory floor; empathise with the pain of the verbal tongue-lashing my wife gives me for leaving yet another piece of scrap telescope lying around the house; yell with vitriolic rage at the ugly orange glow of the encroaching streetlights; share in the depressing gloom of total cloud cover and the continuous rain we have come to “know and love” in this country; enjoy the wonders of the universe. It’s an amazing place!

After 3 roll-off roof observatories (2 were blow-off roof) I now have a driven Pulsar dome sitting on my homemade wooden walls, sitting on a base that was originally a WWII air raid shelter (we think), with a homemade concrete-filled pier with brake-disc pier top.

Equipment

Current and used most:

  • EQ6-R PRO goto mount / EQMOD software control
  • Orion Optics (UK) 250mm f4.8 Newtonian, upgraded Baader Diamond Steeltrack focuser (imaging scope) with ZWO EAF
  • SkyMax 180 Pro 7″ Maksutov-Cassegrain (lunar / planetary) – great but unforgiving of bad seeing
  • Celestron C80ED guidescope
  • QHY168c colour CMOS camera incoming
  • SX Filterwheel 5 x 2″, 7 x 1.25″
  • ZWO ASI290MC (lunar/solar/planetary/guiding)
  • Altair Astro tri-band filter
  • IDAS D3 LPR filter
  • Baader Multi-Purpose Coma Corrector (MPCC)

I’ve gathered up quite a bit of junk over the years. Never seem to get rid of any…

  • Altair Astro RC8 200mm f8 Ritchey-Chretien (imaging scope) – hard work and unforgiving of collimation!
  • Skywatcher Explorer 200P – 8″ f5 Newtonian (imaging scope) – great all rounder – on loan to Nigel
  • Skywatcher EQ6 Pro goto mount – self belt mod, damaged Dec worm but mostly working
  • Celestron C80ED on AZ GTi – grab-and-go telescope now
  • Skywatcher 70mm f/7.1 achromatic refractor (Mercury 705 – used as guidescope) – lent to Emma with AZ3 mount
  • Meade ETX 90RA, unused
  • 10″ f5.1 Newtonian (old Hinds ‘A’ mirrors, given to Jim A.)
  • ATIK 460EX mono,
  • Baader LRGB, Ha, OIII, SI, Rc filters
  • Canon EOS 350D DSLR – modded, fitted with Baader filter (unused)
  • Canon EOS 600D DSLR – screen intermittent fault
  • Brightstar off-axis guider (never use it!)
  • Revelation 0.75 focal reducer for RC8
  • IDAS P2 LPR filter
  • Astronomik EOS clip CLS filter (on loan to Jono)
  • Skywatcher 2″ light pollution filter
  • “Old” Lumicon 2″ Deep Sky filter
  • Imaging Source DBK 21AU618.as (guider and lunar/planetary unused)
  • ADM dual saddle side-by-side mount
  • starlight_xpress_motorised_filter_wheelGemini dual mount bar
  • Some eyepieces and barlows
  • Many, many tubes, connectors, adapters, cables and bits of astro-junk…
