It is worth asking them round to take a look at the moon and saturn
through your scope before too long and you might be able to convince
them to turn it off when you want to go out observing.
Funny but they came out to speak to me when I was observing the lunar
eclipse........which I pointed out to them.......Not even a flicker of
interest.......as for a dark part of the garden......unfortunately there
isnt.......
OK cheap red glasses/goggles are worthwhile then to preserve
nightsight then.
Being in Manchester you must (normally) fewer cloud free nights than here in
Dundee.......everytime (6 times) I have been to Manchester it was
raining........
I'm not any more, but I grew up there.
At 6" you won't get much benefit from light pollution filters in a UK
city environment and especially not on galaxies. It would help a bit
on emission nebulae though. But a second higher mag eyepiece would be
a better buy.
I was wondeing about filters........so many to choose from and not exactly
cheap......thanks for telling me theyre not worthwhile........saved me some
money!
I hadn't intended to dismiss them to quite that extent, but I would
definitely recommend a good 17mm eypiece and a decent 2x barlow before
buying an LPR filter (assuming you have only a 26mm ep at present).
And also if you live in a UK lighting environment of mixed sodium
lights and almost no mercury lights avoid the expensive US branded
brioadband light pollution filters in favour of the home grown and
significantly cheaper visual sodium light polution filter from Orion
Optics(UK). Ask on uk.sci.astronomy for more advice before buying or
find your local astronomy club for ocally tailored advice and take a
look through some of their gear.
Guess once my little girl is better I will make that trip into the
Highlands
for true dark skies and get to see what difference it makes!
That will make a kot of difference. ANd if you have them take a pair
of binocular with you too.
Got some porro prism 7x50s that prolly will suffice........just need a
weather window..........this winter has to be the cloudiest and wettest
since moving north of the border.......Its usually very cold, crisp and
clear with the odd fall of snow.......MUCH warmer this year with temps
rarely near 0 deg C and NO snow.........weird weather
Snow here in N Yorks today. Hills are white again, daffodils look
rather surprised and weather beaten.
PS don't forget to take a star atlas with you to dark skies. It is
most confusing the first time in a truly dark sky - the constellations
do not stand out to anything like the same extent in amongst a mirad
of fainter stars.

Martin Brown
