I am pretty sure that your last two adjustments to centre the star have to be "Up" and "Right" - and that will allow you to tap the icon. The reason it is done like this is to ensure that there is consistency regardless of the scale of backlash in the gears. Try again bearing this in mind. (I have the same app that I use with my AZ GTi and it works like this)

This thread may be useful. Olly Penrice is very experienced - and in the thread he says that you need to look for an image size of 45-46mm to be able to use full frame.

A new NASA documentary has been produced about the mission https://www.youtube.com/watch?v=WM8kjDF0IJU

The excellent 13 Minutes to the Moon podcast (original series about the descent of the Apollo 11 Lunar Module) is having a second series about the way the Apollo 13 mission was saved. https://www.bbc.co.uk/programmes/w13xttx2

A for Astronomy – A hobby with which people can enjoy the night sky, the moon, planets and stars. A hobby that can be done for free, but rarely is. B for Betelgeuse – A star that threatened to do something really interesting for a while, but didn’t C for Comet C/2019 Y4 – A comet that threatened to be really impressive for a while, but probably won’t D for Dark Skies – A condition that we would love to enjoy, as we’re having a few clear nights, with fewer planes in the sky, but we’re all stuck at home, so we can’t go and find these dark skies. E for Evenings – stretching longer and longer as we move towards the Summer. F for Fornax – a constellation that’s near, umm somewhere. I think I knew something interesting about it – didn’t one of the Hubble Deep Field images come from Fornax? Anyway, not visible from here. G for Galileo – one of the first people recorded as having used a telescope to look at the night sky. As it ended up in his House Arrest, clearly it didn’t work out well for him either, but we have something in common. H for Herschel – the first professional female astronomer, famed for discovering many comets. Also her brother and nephew, who worked on a catalogue of objects; obsessives can make it their mission to see all of them. I for InfraRed – a part of the electromagnetic spectrum (discovered by William H) for which you need to travel to high altitude or into space to use for astronomy – well, maybe next year! J for Jupiter – the king of the planets; it’s currently visible in the early morning light, so a great alternative to your insomnia. K for Kepler – Borrowed someone else’s theory and used someone else’s data. One of the first modern scientists. L for Light – the most precious gift sent from astronomical objects to us observers across billions of miles. It gets lonely though, because it doesn’t hesitate to join up with lots and lots of our human made light when traversing the last 60 km or so. M for Magnification – the thing that most non-astronomers think is important, Oooh! x625 N for Night-time – when we practice our dark arts; they say practice makes perfect – well, we’re still practicing. O for Occultation – a phenomenon when one object obscures the light from another, for example, when a planet or asteroid blocks the light from a star. Most often occurs with clouds. P for Pluto – used to be a God, then a Planet, then a cartoon dog, and then (controversially) not a Planet any more. We used to have proper controversies in Astronomy: the nature of the spiral nebulas, the Big Bang vs Steady State, proper controversies. So maybe P is for Proper controversy instead. Q for Questar – a brand of telescope for people who don’t know the meaning of “Oh, isn’t that quite expensive for a hobby?” No, that does NOT mean people like us; we can justify every penny we’ve spent on Astronomy. R for Refractor – the best type of telescope (runs off to get popcorn) S for Stars – strangely, it’s almost the case that the least interesting thing in amateur astronomy is a single star – we love them in the plural and will spend a fortune on GOTO systems so we can see them in binaries, asterisms, open clusters, globular clusters and galaxies, but a single star by itself – just a dot. T for telescope – a device for taking light that has travelled free across millions of kilometres and compressing it into an image that we can then inspect with a magnifying lens. Like an insect on a pin. U for Uranus – prime evidence for us astronomers' sense of humour V for Venus – generally the answer to the question “what’s that really bright star I can see in the evening, is it the Pole Star?” W for Cassiopeia – don’t argue. X for X-Ray – it always comes down to either X-Ray or xylophone, and although Sir Patrick played a xylophone we don’t use them in Astronomy. Y for Year – the time period based on the Earth’s orbit around the Sun. Quite straight forward, which is why we have Sidereal Year, Tropical Year, Anomalistic Year, Heliacal Year, Julian Year, Gregorian Year, Sothic Year, and several others. Z for Zodiac – the astrologers’ 12 star signs through which the sun passes through the year. We’ve moved on now, so we now have 13 constellations through which the sun passes in a year. So clearly we’re better, like that bit from Spinal Tap.

Announcement from the NWAF committee It is very sad for us to say this but in view of the escalating Covid-19 situation, the North West Astronomy Festival management committee have reluctantly concluded that it is in everyone's best interest that we re-schedule the Festival to 2021. We have made huge progress in planning the event and as a team we are well positioned to work towards an even better Festival in 2021. We would like to thank everyone for their support so far, especially the astronomy societies who have been so keen, and the wonderful speakers and traders who had agreed to come along. We will be back in touch as soon as things settle down. In the meantime, watch for updates on our website www.nwastrofest.co.uk and via social media.”

Better than clashing with one or the other though!

Update on 18 March 2020 In the light of the unknown duration of special measures during the Covid-19 epidemic, the decision has reluctantly been made to postpone the NWAF to 2021 The North West Astronomy Festival is back, with a new date and a new venue. https://nwastrofest.co.uk/ The North West of England's only major Astronomy Festival has moved to The Engine Rooms at Birchwood, Warrington, WA3 6YN (convenient for M6 / M62) and has a new date Saturday 24th – Sunday 25th October 2020

A memorial service for Andrew will be held at the Wincham Hall Hotel, Wincham near Northwich, Cheshire at midday on Tuesday 28th January.

Andrew had moved back to UK last year, but Sue is still running Astrofarm, with the "Astro-facilities" available to guests as before.

I'm saddened to announce the unexpected death of Andrew Davies, astronomer, teacher and inspiration to many. He helped many develop in our great hobby, through his teaching, the clubs he helped set up, through his work fronting the North West Astronomy Festival in Runcorn, and in setting up Astrofarm France. He will be much missed.

As Cyril has pointed out, SpaceX use RP1 (basically refined paraffin) and LOX as fuel and oxidiser - the refrigeration required for Liquid H2 is much greater than you need for Liquid O2, so the engineering challenges is far greater, and apart from that, the mass density of LH is much lower than that for RP1 - which would require significantly larger fuel tank stages. Although the Saturn V rocket did use LH / LOX, it was only in the Second and Third stages. If they had tried to use it for the First Stage, the tanks would have had to be about twice the diameter.

You can play with the scale factors on this Google Sheets on my drive https://docs.google.com/spreadsheets/d/1GoGmffEo6rH0E4C0O5qQ-nLCOocw3P8YzHN6r1oW3RQ/edit?usp=sharing You should be able to select your 'base' planet using the blue dropdown, and then select what size you want it to be using the left hand yellow cell. # The right hand yellow cell allows you to select the size you want for the orbits (obviously a completely different scale to the planets). I have a 15 metre tape that works well for Sun - Neptune, so Jupiter at 2.6m fits that scale.

Our Astro Society was asked if we could lead a couple of sessions for a local Cub scouts group to prepare them for their Astronomy Badge. A lot of the content is around the Solar System, so we thought that we'd assemble some appropriately scaled models. At a craft shop we were able to pick up Polystyrene balls in following sizes which are pretty close to representative. 10cm - for Jupiter 8cm - for Saturn (about 5mm too small) to which we added a card 'hoop' for the rings - inside diameter 9cm, outside diameter 19cm 4cm - for Uranus and Neptune (c 5mm too large) 1cm - for Earth and Venus (1 & 1.5mm too large respectively) 0.5cm for Mars and Mercury (Mercury about 1mm too large) If you can get a beachball about 1 metre in diameter, that will stand for the Sun. We painted the 'planets' in appropriate colours using acrylic paints and they looked pretty good. Edited to correct size for Mars / Mercury from mm to cm.

If that's all you have on I'm not surprised!

Hi and welcome. You're fortunate to have a few local astro societies if you want to meet up with like minded people. I don't know anyone from Chester AS, but they're quite local to you. If you're able to get over to near Old Colwyn, the North Wales AS meet for observing at the Community Centre at Llanelian on the second Tuesday of the month - i.e. tomorrow. If it's not clear, they'll have a short talk or two instead. They also have a talk meeting at Llanrhos Old School (nearer Deganwy) on the fourth Wednesday of the month. They're a really friendly group, and I try and go to most of their 4th Wednesday meetings.

Solarsphere (Astronomy festival at Builth Wells) is 14th - 17th August next year. http://www.solarsphere.events/LatestNews.html

We have a signed copy that we bought at this year's Solarsphere. And one of our club members has his image of M81 in it.

It's awesome isn't it. What I would say is that it's worth seeing it in a variety of locations, as your response to it can vary depending on what room its in. Here it was in a church in Llandudno

Late response, I know - it's been a busy week, but here's the page I saw in the download. If the actual offer is better, that's great.

My version downloaded this morning is saying "£16.50 every 6 issues", so a bargain, but not quite as much of one

Have you all seen the error on page 4 of the download? Repeated on page 55 of the new one?

It's been a busy day!

Mid Cheshire have their meeting on the last Friday of the week; so feel free to visit us too. we're at the Forest Explorers cabin behind the Cafe and Bike place in Delamere Forest. If it's clear, we are likely to observe afterwards, but otherwise why not join us at the pub nearby. https://www.midcheshireastro.co.uk/

Images of the Meade Schmidt Newt scopes (from online reviews) suggest they come with an extension tube, but the OP's photo doesn't show one. To the OP - can you get back to the previous owner and see if they have the extension tube put away somewhere?
