because we do it every day and I fly the union jack on my workstation to rub salt in it......

If I was you I would keep it at the length you received it you never know if you add equipment to your scope and you need to offset the balance they are made of aluminium so a good hacksaw with a steel blade would do the job but keep it at the length you got it they are cheap anyway if you need another dovetail bar

we have a rocket at work for cleaning out steel tubing and rebris from within me and my facing colleague about 15metres away like a petrol pump nozzle yet filled with what ever we can find and fire at each other at 100 psi (stupid kids) passes the day, the best was a milky way hit him right on the noggin (head) don't worry he lived and ate the said chocolate bar don't tell HSE.....

Helen why only half you got to go the whole hog? the bigger the effect the better

love May great like today was a bank holiday to respect the …. and yes 11 nov another bank holiday

dam new I went wrong somewhere in my calculations yep and watching uk tv an hour behind a real pain in the...……. knowing you have to get up for work

the big sandcastle building next to the old echo building had the largest open plan office space in Europe at the time on one floor https://www.the-modernist.org/news/2018/6/23/63offgizjbg9bnosd1ixz95hz1dbz0

Just seen your location I used to work at the sandcastle (Royal Insurance) if they are still there? back in the 90's

Can't wait for my granddaughter to arrive gotta wait till feb albeit she will be a newborn and my first one. Just spend the day decorating at my sons apartment as he is moving with his wife to their first house in a few weeks (wallpapering hate it with vengeance) eyesight not the same anymore kids of today can't do anything practical (dad can you do this) a big learning curve awaits.....

What mount do you have this would/could help those that know the answer to your question

https://www.npl.co.uk/skills-learning/outreach/water-rockets/wr_booklet_print I think the method we did at school albeit secondary at 11 was a fizzy drink bottle 1/2 filled with meths swilled around with cap on with as small hole in it then contents emptied so just the vapour left in said bottle then bottle placed in some gutter offcut at and angle then physics teacher with a wick lit placed at bottom of bottle and presto (don't think that this is aimed at 9 year old's ) but stook with me as my best friend lit his rocket and set fire to his brand new school blazer sleeve... LOL

+1 get the book read an re-read it does help

And their was me thinking you where going for the x=prize project and beat Richard Branson

What plans do you have in mind for the rocket...….

so mercury is 8.3-3.2=5.1 minutes venus is 8.3-6.0=2.3 minutes etc etc no prob

Mercury 0.387 193.0 seconds or 3.2 minutes Venus 0.723 360.0 seconds or 6.0 minutes Earth 1.000 499.0 seconds or 8.3 minutes Mars 1.523 759.9 seconds or 12.6 minutes Jupiter 5.203 2595.0 seconds or 43.2 minutes Saturn 9.538 4759.0 seconds or 79.3 minutes Uranus 19.819 9575.0 seconds or 159.6 minutes Neptune 30.058 14998.0 seconds or 4.1 hours Pluto 39.44 19680.0 seconds or 5.5 hours Time for the sun to reach each of the planets so if we subtract 8.3 minutes from the above that is a rough guide as to how old each planet is as per Jupiter 43.2 minutes and then subtract 8.3 minutes = 34.9 minutes ago from good old earth etc

https://image.gsfc.nasa.gov/poetry/venus/q89.html To calculate how long (Time, T) it takes light to travel from Venus to Earth, you need to know how far away Venus is from the Earth (Distance, D), the speed at which light travels (Speed of light (S), scientific symbol: c). Then you use the following formula: T = D / S Speed of light: ‘The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is 299,792,458 metres per second (approximately 300,000 km/s (186,000 mi/s)).’ Speed of light - Wikipedia Earth-Venus average distance: On average Venus is 40 million kilometres away. Sometimes Venus is further away, and sometimes a little closer. How Far Away is Venus? You can get an approximate value by using 300 000 km/s for the speed of light or you can convert everything into metres and metres per second. 40 000 000 km = 40 000 000 000 metres (you multiplied by 1000, because there are 1000m in a km). T = 40 000 000 000 / 299 792 458 = 133.43 seconds (rounded up) Now, you divide the number of seconds by 60 (because there are 60s in a minute): 2.22 minutes (rounded). 0.22 of a minute is (0.22 x 60) = 13.2 seconds. So, on average, it takes 2 minutes 13 seconds approximately for light to travel from Venus to Earth. This means we are looking at Venus as it was just over 2 mins ago.

in the setup screen under guiding "calibration" you have set at 50mm needs to be changed to 162mm

Gordon, Where I live in November no problem for fires just not in summertime local marie as you state gives permission l'arrêté préfectoral

You could just pile up the cuttings for Nov 5th and a wopping bonfire saves on the trips to the dechetterie? Could be a bit smokey

My problem was Samba not associated with correct windows workgroup now can see my windows network from rpi. thus using filemanager to edit samba conf file as admin but all ok now a bit of a learning curve Raspbian vs ubuntu

So correct me if I am wrong terminal then run sudo pcmanfm ? what a pain in the …… also browsing local network a pain as well. that's Debian for you I suppose

Flirc case turned up today and my son also arrived with my birthday present RPI4 straight in the case and hooked up to the power. bingo in business so far so good running at 45 degrees so cool as can be, even tried running gimp and barely moved in temp so now got to configure indi, one thing I dont like on Raspbian is file manager no admin access to edit files a pain in the neck have to use terminal and nano. Ex ubuntu user... Andy

What size dome are you using and how are you fixing it? Regards Andy
