    Thanks, my lappy has both Nvdia and Intel graphics so have not noticed this issue yet but will have a look. Alan

    The 1903 update did disconnect my WiFi also and had to enter my password again and changed a few icons but mostly painless. Alan

    I had it a couple of weeks ago, its more of a new OS rather than an update but all is fine with my lappy. Alan

    The Newt idea is not for the inexperienced but works in a similar way to the Herchel wedge, as mentioned before the projection methods are the safest form of Solar observing. Alan

    Its the way of the world I am afraid but does have benefits, Albert Eisenstein was the biggest celebrity in the world of science and am sure he inspired those that followed... and most importantly the general public. Alan

    I like the padding, the staring into the distance and most of all the soundtrack although that seemed a bit toned down this week, its called engaging with the masses who dont yet realize they have an interest in science... Alan

    I agree, he would certainly be near the top of my list of people I would love to have a drink and chat with down the local pub (bar). Alan

    Thanks, gradients are a pain with widefield lenses especially if you have localized light pollution..... Alan

    I am confused as to the scale of those images, did you do massive crops? and why would you crop so heavily with such a lovely widefield lens... Alan

    No one has mentioned it but you can make a very safe dedicated solarscope by removing the silvering/aluminium from the primary and secondary mirrors of a "small" Newtonian scope, you would need an ND filter and perhaps a IR cut filter too for observing but should be fine without for imaging.

    Well that was enjoyable, gave me a real feel of what Mars has gone through in its life. Alan

    Watching, I do like Brian Cox as a presenter.... Alan

    As above just general fresh air and daylight will do the job even if its cloudy, make sure the path of the Sun doesn't go down the tube... Alan

    Plenty of daylight will normally stop the growth but in bad cases its worth stripping down and cleaning with a "lens cleaning" solution as the fungus will etch the glass if it takes hold. Alan

    I would second all the advice given but would add that reflectors are not suitable for solar projection as too much heat will hit the secondary, most reflectors also have the option to use a filter over the whole aperture or just by covering the additional small hole in the endcap.... Alan

    Lots of them here...... https://www.amazon.co.uk/Hello-Darkness-Friend-T-Shirt-Black/dp/B01KZPBNMI Alan

    The site seems faster once you are in but takes much longer than before to load up.... Alan
  18. Alien 13
    I like this, would suggest Moon with clouds too.... Alan
  19. Alien 13
    Sorry Olly I misread your post, exciting times ahead.... Alan
  20. Alien 13
    I am sure that the same was said of photographic plates but look at how a relatively tiny scope can now easily out perform the great 200 inch monsters even with a DSLR..... Alan
  21. Alien 13
    I imagine any new camera tech will quickly appear in mobile phones first as this is the biggest market and the price will come down very fast.. Alan

    Its amazing that "Fireball XL5" had the right idea all those years ago I dont know the exact figures but a very large proportion of a rockets fuel is used up just getting it to Mak 1..... Alan
  23. Alien 13
    The Mak and SCTs for that matter use spherical mirrors so it makes little difference to where they are pointing, any collimation has to be done at the front end... Alan
  24. Alien 13
    Looks good not seen that model before so had a peek online and it was nice to see it uses standard AAA bats, I have something similar with the giga t pro but it eats the expensive CR2 batteries so does not get used much. I do agree with keeping leads down to a minimum on portable mounts. Alan
  25. Alien 13
    I thought that too as its where the 130pds and ED80 threads reside. The Samyang is one of those products that is so good in that it is ideal for beginners with a DSLR on a tracking mount and experienced users that want to go very deep.... Alan
