recall my work colleagues taking the "P" out of it because it had a
square section tube instead of tubular. But then he explained that the square
section tube did not suffer from air eddys as tubular tubes do. Sadly I think
I was so busy using the scope that I never got round to taking any photos of it
before I sold it a few years ago. I hope it is still going strong now!
I use the Helios scope which is almost 6 years old now (having mirrors re-coated
later this year). I do have a nice framed photo of the Moon, sat on a shelf at
home, taken through the home brewed scope with my trusty old 35mm SLR camera.
eclipse photos were taken through a small Skywatcher stumpy refractor I bought
to take to Spain in 2005 for the annular eclipse out there, October 5th 2005 I
think. Got some nice photos even though some of it was clouded out, AHH those
Helios 200mm scope
images were all taken from my back garden, in Park North, using my Helios F5 200mm
reflector and an Opticstar PL130M monochrome astro camera (1.3mp but with zero
compression). Images stacked using Registax3 and Gimp image manipulation software.
Notice the homemade mount for the secondary mirror, with curved, instead
of straight vanes. The idea of curved vanes is that it reduces the diffraction
effects of the spider. These effects are normally seen as the classic spokes around
bright stars. With the curved vanes you do not get that effect and therefore better

suppose I have always been interested in space, watched a lot of Star
when younger. Have vague memories of the Apollo missions in the
was about 5 then). But what really fired me up was Christmas
1998 when my
wife bought me a telescope from Argos (oh dear!!). It
wasn't that wonderful
but I persevered with it until I managed to track
down Saturn. I couldn't
see very much detail but enough to have that WOW moment. Here was something real
that I had only seen on TV or in books before.
remember that Christmas we went to the library and I borrowed a
video about astronomy. We watched it and found out about the solar eclipse the
following year, in August 99. That was it.
Our holiday was planned around
that date and we visited Dartmouth, Devon where we stayed for a week and viewed
the eclipse from our campsite, but thats another story.
In the mean time
I had tired of the little refractor from Argos and got some books on DIY telescope
making. Within a few weeks I had amassed some MDF and a mirror set, some springs
and bolts and set about building a six inch reflector on a dobo mount.
