    Hi folks,


    Good oul Santa brought the above telescope. Have been reading the posts here and seems it gets mixed views. Anyway am a real amateur so willing to learn and happy to start with this telescope.

    As regards the software etc for automatically updating the Autostar, where do you guys recommend...........

    Will keep a close eye on this thread.

    I got this for xmas also. I'm having trouble aligning it and getting a good focus on it. It's a grand entry level telescope though.

    There are probably a fair few people with this telescope by now, so I thought I'd revive this old thread (last post, 2 years ago tomorrow) :eek: ... so that we can post any ETX 70 related stuff on here ...


    Assembled the ETX 70 and the kids immediately showed an interest, scouring the surrounding hills for anything of "interest" :rolleyes: and I couldn't get anywhere near it for the rest of the day :( ...

    Came in from a few drinks last night and there was just a 5 minute break in the clouds, so I had a quick look at the moon, using the 12mm lens... nice, clear image, then whammo ... the clouds obscured it again!:mad:

    Hoping for better conditions tonight ... but it's not looking good! :rolleyes:

    The two star align works well, and there are a good range available. I haven't used the goto much, the 25mm eyepiece gives a good enough range to browse and you can hop easily from the 14mm if you have a star chart. I'm finding the autotracking a bit off, planets tended to drift out of view at higher mags.

    Here's a link to a youtube video detailing the ETX60, but it covers everything for the ETX70, (except that the 70 has a separate Barlow lens, rather the built-in one on the 60) .....

    Yeah, I need a compass myself... although the constant cloud cover hasn't given me a chance to see anything yet (except a couple of minutes of the moon on Xmas night) let alone try an alignment! I just love the ultra compact size, so it can just sit permanently in the seating area of my kitchen (once the tree comes down) and we can view the surrounding countryside during the day as well.

    I have noticed though, these last couple of nights, that my neighbour has decided to leave his outside lights on until quite late (after 1 am last night) and the moon travels right over his house, so quite a bit of pollution. Hopefully, he's only doing this over the holidays and he'll turn them off at a reasonable hour once he gets back to work.

    Keep up the good work ... only don't feed the ducks and swans ... well not in your back living room, anyway! :eek: :D

    Like others got this scope for christmas, on a beautiful clear night decided to check it out, following the youtube vid which was handy, set it up correctly, but goto says that the moon is below the horizon!!!!!

    its right there in front of me, what am i doing wrong?

    :eek: Dunno :confused: ... I'm gonna try for the first time myself later. :( Did you set the correct date and time in the handset? :)

    but goto says that the moon is below the horizon!!!!!

    Are you in Australia by any chance? :D


  • Registered Users Posts: 2,160 ✭✭✭mountain


    Are you in Australia by any chance? :D[/QUOTE]

    not with the cold down here!

    set time and date, it now thinks the moon is up, but is pointing well away from it!

    let me know how you get on

    Will do... I'm gonna give it a try at about 7.30 or so.

    Was actually looking at the moon earlier... got some nice images, but after letting the wife have a view, she's finally come round to what I've been telling her for years ... that length isn't everything! :eek: ... focal length that is! :D
    I was initially going all out to get the biggest image I could, by putting the 6mm and barlow in at the same time! :eek: but of course, quickly realised that a smaller, better resolved image is better than a very hard to focus, blur! :( ... I hope the wife takes my new findings on board ... "Length isn't everything" :D


  • Closed Accounts Posts: 87 ✭✭Diamonddec


    Oh crap! :( ... I can see the moon fine, as there are no clouds around it. I would say it's probably about south-east, but look further north and it's cloudy. I am a complete novice in naming the stars, but I'm trying to find the big dipper and get to Polaris from there, as my reference to true north. I MUST GET A COMPASS ... I MUST GET A COMPASS ... Adding to that, it's freezing, and the snow (ice) around the house is something that Torvill and Dean would be happy to perform their "Bolero" on! ... Let alone me wobbling about on it with my new telescope! I'll have another look at the cloud cover to the north in a while and see if I can see any more stars!....

    spent the last hour outside the back of house with my etx 70 looking at the moon and even managed to see Jupiter and 3 of its moons. I am also having trouble with the autostar but i reckon its cause I am to impatient to set up properly. I did download stellarium so that helps with id-ing any planets. I am just waiting to jump into the car when there are no clouds and no moon so I can see much clearer.

    Nice one! :) I know what you mean about being impatient! :( ... It's not easy to faff about outside in extremely cold temperatures when all the while, the wife is shouting through the window, telling you to stop larking about and come on in for a Baileys! ... and I haven't even got my telescope out! :eek: ... I'm just out looking at the stars, still trying to lacate the flipping Big Dipper .... :confused::D


  • Registered Users Posts: 3,483 ✭✭✭Ostrom


    re alignment -

    I noticed on my own that the azimuth graduations on the scope are free to move about (the piece of paper used for the scale is not fixed in position and can be moved about by touching). Zeroing the scope on this axis (for me anyway, but I would imagine it happens on a few if mine moved so easily) is inaccurate.

    Shouldn't really matter as it has to be aligned manually anyway, it just throws it out of whack if you're relying on the auto for a ballpark direction to find your star


  • Closed Accounts Posts: 87 ✭✭Diamonddec


    Thanks for that efla ... definitely something to bear in mind! ... :)


  • Closed Accounts Posts: 87 ✭✭Diamonddec


    Another totally cloudy night up here in County Derry! :rolleyes: ... Very hazy moon and no stars visible. :( There was one solitary thing to look at for a little while ... it was roughly east ... but just a very small, light orange dot! ... I was thinking that maybe it was mars, but, even through the telescope, it was still very small. :(


  • Closed Accounts Posts: 3,327 ✭✭✭Sykk


    Argh same down here in Westmeath. Really wanted to browse around the stars tonight :(

    yep that would be Mars


  • Closed Accounts Posts: 87 ✭✭Diamonddec


    Thanks dbran ... I wasn't 100% sure! :( ... but after looking at the :) Cartes du Ciel chart, I knew that mars should have been in that locale!
    I still haven't managed to do an "alignment", though I got a compass today, so, if the overhead conditions permit tonight, I may give it a whirl ... although the outside of our house is still like a skating rink! :( ... I just wish we would have a downpour for a half hour and wash it all away! :mad:

    Hi Diamonddec

    No problem.

    Its not so much a compass that you need. Finding North is easy just find polaris. As you know "magnetic north" is not true north but is offset by a few hundred kilometers so it is no good. I dont think you have to be deadly accurate with it anyway.

    What you really need more then anything is to level the tube. Turn the scope anticlockwise until it hits the hard stop, then back a 1/4 turn so the tube is over the computer pannel. Then lift the scope up and place it down so it faces north. Scope is now in the "Home Position". Level the tube with a bubble level. Switch on the autustar, pick two star allignment or easy align. It will ask for two stars which you centre using the autostar controls only. (do not centre manually). It should then give you successful allignment and you are good to go.

    If it dosent work check the date and time are correct, also check the batteries are fully charged. Make sure you are in astronomical tracking mode.

    Hope this works

    :eek: Mate, if I could find Polaris that would be a major achievement! :( ... TBH, I've now kinda worked out where it should be, using a house a couple of miles from me, as a reference point and Google Earth! :confused: ... Apparently, if I go to the next field 300 yards right of the house and go straight up ... then Polaris should be there! :D

    Seriously though, it's another fully overcast night and there is not a single star visible! :mad: ... So another inactive night.

    Thanks for the setup/home position info... much appreciated. I'll keep you posted about my success (or not):( as soon as the conditions allow an attempt at it.

    I find with my compass, which is digital, its fairly bang on. Well used with stellarium.
    It told me Mars was at 80 deg the other night and i moved to 80 as marked on my compass and there it was.

    I guess my compass (dive computer) is better than my scope.

    Methinks you need to learn the sky first.:D Even with goto you will need a basic knowledge of the main constellations. How will you be able to pick the correct allignment stars otherwise :)

    :o I think you're right though! :( ... I should actually be spending these overcast nights swotting up on my constellations! ;) ... There isn't a test on Friday, is there? :(:D

    I have been out for the last few nights looking a various different objects with my meade etx-70. I saw jupiter every night and its moons but i was wondering what type of telescope would i need to be able to make out colours of the planets. I have been able to find most things the autostar has on when its night and they are above the horizon. I am presently in my back garden and yes there is some light polution so will it make an enormous difference going into the countryside on a moonless night.
    Thanks

    Am out tonight for the first time and decided to use Autostar to get me going. However, all around my drive is still like a skating rink, with just a few clear patches, so I cant venture too far away from the house, so have a limited view of the sky ... although this is uninterupted from south to north east. It is a fairly clear night and for the first time, I had no difficulty in finding Polaris using the Big Dipper. I pointed the telescope north, leveled the tube, turned Autostar on, put in the date and time and chose the easy 2 star alignment. Unfortunately, the stars it chose were on the other side of my house, out of sight. So I started again and chose the one star alignment. I named the Big Dipper "pointer star" Dubhe. However, the telescope slewed too low and pointed more towards the direction of Mizar (although not directly at it!) :confused:

    It only had to move a few of inches, FFS and still couldn't manage it! :mad:

    Any advice would be gratefully accepted! ... I must be doing something wrong! :(

    Anyone got or used them? ... worth having?

    If it gives you the option make sure and select daylight savings - no when you switch on Autostar and are about to aligning the scope. I made that mistake at the start and it threw the alignment off by a good bit.
