    The Meade LX-series telecopes have many fans. They can stand for some work when first purchased - or, in the case of buying a used one - checking over to see if a few upgrades are warranted. But all-in-all, Meade LX SCT's are excellent. Which explains their popularity. And explains why I've bought 2 of them - both 12" at that. They're that good.

    Enjoy your Meade!

    Hi Dave.

     

    after a little advice please.

     

    on your advice I bought a 2" dielectric diagonal with an 8mm planetary eyepiece.

     

    managed to get a clear night so used it!

     

    the diagonal made it so much easier to use but I think it needs setting up and collimating.

     

    the image I got wasn't great. I used the 8mm on the moon and then had to revert back to the 26mm..

     

    parts is of the image we're pretty clear but overall I'd say 70% off a great image.

     

    just wondered what the best way forward is.. seeing that you also have a Meade sct..

     

    cheers

    Yes, I agree and that thought did run before I commented.  My telescope also needs collimation, and EP's, but came to me sufficiently collimated for me to play with without any initial adjustment, it also came with two perfectly adequate EP's which enabled me to get some early satisfaction and being a reflector I didn't need a diagonal.  This Meade LX90 seems to have caused its owner a certain amount of consternation and they don't appear to have to the immediacy of some satisfying use early on which I think I would have found really disappointing - I took mine outside plonked it down found the moon and went 'wow'!.  I have seem a good number of people with similar telescopes to this LX90 on there and have often admired their compact form compared to my own and I can't shake the feeling that their sheer value must make them superior instruments to my own, but I think I am still glad I wasn't swayed into considering one. - there seems far more things to consider when you buy things for them for one thing!

    Hi Joc et al.

    Thanks for the input you've given. All input is great and joining this forum just shows me how many great astronomers there are out there with the dedication to help a new boy like me..

    To clarify... I did a lot of research before buying my Meade LX90 8" SCT. I didn't want to pay the full retail price, as it was my first scope so bought mine used.. paid less than half retail price.. 

    So when it arrived I had already paid a decent amount for it and it didn't come with the extras that it would have if new. 

    Being a compete new comer I  had and still have pretty much no idea about using it.. hence the 3 pages of questions.. Going forwards I want to buy quality but value to really get the most from my sct. I know it has sooooo much potential and I can't wait to utilise it!

    Hence the lack of diagonal, decent eps and my inability to realise the telrad was on back to front and the LNT was plugged into the wrong port.

    Only by asking questions and everyone here being so helpful am I getting to grips with the whole space thing and what will make my slightly hindered amazing SCT deliver what it is capable of..

    I have ordered a 2" sct star diagonal with 1 1/4 reducer plus a 60° field 12mm gso eyepiece, all thanks to input from this forum. Just pondering about the dew shield and mains power supply..

    On my first use I did see the craters on the moon in amazing detail. However due to the lack of supplied diagonal and my incompetence of setting it up if wasn't a fair first use of the telescope.. hence the initial disappointment when I had read up and seen what it is capable of.

    I am just awaiting delivery of the aforementioned items and a clear sky to really see what the telescope is capable of...

    Watch this space...

    Again... Thank you all so much for your input, time and effort in getting me to a place where I feel more comfortable with my new hobby and I can't wait to stargaze!

    Cheers.

    You can buy a 1.25" diagonal which will push straight in the back of the scope, but to be honest, you would be better buying a 2" diagonal, I can recommend one of these.

    https://www.telescopehouse.com/accessories/diagonals/diagonal-dielectric-99-quartz-lx.html

    it will screw straight onto the back of your scope and allow you to use 1.25" and 2" eyepieces. The other alternative is to buy the diagonal you mentioned earlier but you will need a 2" to SCT adapter.

    you also asked about eyepieces. Your 26mm eyepiece will allow you to see the bands on Jupiter, the rings of Saturn and many deep sky objects as well as crisp views of the moon and its craters. Of course, your seeing will be better if your sky is dark, wait till there is no moon to look at deep sky objects.

    i have an LX90, it's the second one I have had. After selling my first one, I have had a pretty comprehensive list of other scopes including a 12" dob, 9.25 Celestron and 10" Meade LX200, but I have returned to an LX90 ACF  because I love the ease of use and views this scope gives me.

    i would also recommend a few more eyepieces, if you have dark skies, get a good 9mm, otherwise 12mm is about as small as you will need, then maybe 18mm, 32mm and a wide angle 40mm. The 40mm will give you lovely rich wide field views.  

    There are lots of recommendations on makes and styles of eyepieces, I have a set of Meade HD60 eyepieces and a 2" fit super wide angle 40mm Aero eyepiece that gives superb views of big areas of the sky.

    i buy a lot of my stuff from FLO ( obviously) but I bought all my Meade kit from Telescopehouse. They are very knowledgeable about Meade and I had my scope fine tuned by Steve Collingwood of SC Telescopes. Both in Tonbridge in Kent and Steve is a Meade trained technician and well worth contacting if you need to get your LX90 up to scratch, or maybe just some more specialist advice.

    stick with your LX90, it's a superb telescope and good luck.

    Thank you such much for your input..

    Can't wait to get a diagonal, New eye piece and a clear nights sky!

  7. Hi all. This is my SCT. Push fit 26mm plossl with thumb screw to hold in place.

    So assume I can buy any 90° push fit and just use the thumb screw to hold in place?. Then the new eyepiece will push fit into that and thumb screw again..

    I assume that's correct?.. I've held off buying anything as a tad unsure what will and what won't fit. ? Already cost me a pretty penny.. want to make the right choices.. 90° to make viewing easier then probably a 12mm eyepiece to wow the kids!.. and me ?

    Cheers.

    My first scope was an LX90 too, it's a good quality instrument and you can get a lot out of it, you just have to be patient and work through the various challenges.

    Collimation

    Collimation is important, and you can do a quick star test to get a rough idea of what it is currently like, as mentioned in the post above. I'd be inclined to only check the collimation to try to gauge if it's out or not without trying to improve it initially though. If the inner part of the donut is roughly centered when a star is out of focus, it's likely close enough to make do with for a couple of nights whilst you get used to everything else first. It will also give you a reference point for when you do start to try to improve collimation which is quick to do once you know how (5-10 mins) but can easily end up taking up a few sessions when you're learning.

    Cooling

    The comment about letting your scope have chance to equalise the temperature with ambient is vital, don't bother trying to collimate until the scope has had an hour or so to equalise.

    Alignment

    As far as stars for alignment not been visible, do you mean the scope isn't pointing in the correct direction or close enough to them, or that they're blocked by trees/house etc If the latter, you can request the autostar select another star. I forget if it's via pressing mode or the up/down arrow off hand though. It's in the manual either way.

    As long as your tripod is roughly level and you put the scope pointing north and have the date/time/location correct, the scope shouldn't be too far away from the target star, although it's unlikely to be in the eyepeice, it should be in the finder or very close.

    One tip for pointing the scope north. Center polaris in the eyepeice and then slew the scope in the vertical direction only until it is horizontal (use a spirit level when you're close). That is assuming you're in Alt/Azimuth mode and not using a wedge, check your autostar is correctly configured for that. If it's set to polar and you're not using a wedge you'll run into all kinds of problems.

    Focusing can be tricky to do well at first and on some nights if the seeing is poor you'll never really feel like anything is in focus.

    Dew Shield

    The earlier post about a dew shield, do not ignore that advice. Get an inexpensive 8" flexi shield which should be around £25 (or search the forums for examples of people building their own), it's invaluable.

    SCTs will collect dew like there's no tomorrow and once it sets in, that's it, you're done for the night as you can't just wipe it off and even if you heat it to evaporate, prevention is better than cure as deposits can build up on the corrector plate.

    I as I imagine most others do, use a dew shield + heater strip. You can avoid the cost of a heater strip for a while, but I would buy a dew shield before anything else, although I'd also consider picking up a star diagonal as well, your back will thank you on that one :)

    A first scope is quite the learning curve as you'll be unsure if issues are you or the scope at first. The comment about heading to a astro meetup is a good one. Other than that, try not to get frustrated, a bit of patience and persistence and it'll eventually become second nature and you'll wonder why you ever struggled :)

    Thank you for your amazing advice and input..

    Lots to take on board but getting an idea of essentials I must buy to get more out of my scope...

    Mainly 90° tube, 12mm eyepiece and a few shield...

    Cheers.

    I have a SCT of the same aperture and focal length. I use 25mm, 15mm and 8mm eyepieces with it. All are 1.25". You only want 2" eyepieces for lowest power/widest field as the 1.25" are cheaper and more widely available. Plossl types are good enough at 25mm and 15mm unless you have exacting requirements or deep pockets. I have not invested in any lower power (wider field) or 2" eyepieces as I have other scopes for that.  For my scope the cost of a 2" visual back, 2" diagonal and 2" eyepiece adds up to an off-putting sum. But if you have no other scope you may feel it's worth it.

    You will need to get the finder (finders) to work and be accurately aligned before you can proceed to aligning and using the GoTo electronics, as the field of view of the main scope is fairly small. Assuming the hardware works as it should, you will scarcely need the finder once the GoTo is set up, and you should be able to find large numbers of objects.  While GoTo systems differ, there is usually a choice of alignment modes e.g. One Star or Solar System object - quickest and least accurate, Two Star - more accurate , Three Star - most accurate and the most fiddly.

    Even if the mount has an equatorial wedge (and corresponding settings in the software) you should get used to using it strictly in alt-azimuth mode (mount base horizontal) first - that may prove challenging enough to start with.:icon_biggrin: The equatorial wedge is principally for astrophotography.

    I'm not sure how your Meade is powered, but if it uses internal dry cells, think about getting an external power pack for it soon.

    Thanks Geoff..

    Just managed to get the LNT module working.. had plugged into the wrong hole... So from set up I had the telrad the wrong was round, so didn't do anything and the LNT plugged into the wrong hole.. So didn't work either.. Got rather frustrated trying to use my phone app to level and find magnetic north at 12.30 am! LoL...

    Been cloudy skies since so just waiting for a decent evening to try the telescope out again.. LoL... Learning curve in deed.. the school boy errors don't help.

    Thanks for your input.

    Were you able to determine that you can in fact connect a 2" diagonal to the telescope?  You will need a specialised adaptor to connect one, if one is not already fitted...

    https://www.telescopehouse.com/accessories/meade-lx/meade-sct-thread-to-2-adapter.html

    The goal of upgrading to the 2" format is in realising the lowest powers with the telescope.  For example, you can insert this 2" 56mm ocular for one of the lowest powers with your telescope...

    https://www.harrisontelescopes.co.uk/acatalog/Meade_Series_4000_56mm_Super_Plossl_Eyepiece_2_.html  (36x)

    That's why owners of Schmidt-Cassegrains outfit them with a 2" visual-back, for the lowest powers.

    At the moderate-to-high powers, the 1.25" format is generally preferred.

    An 8mm ocular will give a power of 250x...

    http://www.365astronomy.com/8mm-the-planetary-uwa-eyepiece-58-degrees-1.25.html

    You can back off the power a bit with a 9mm...

    http://www.365astronomy.com/9mm-the-planetary-uwa-eyepiece-58-degrees-1.25.html (222x)

    ...if the atmospheric seeing will not permit 250x.  

    Or, you can go with a 12mm...

    http://www.365astronomy.com/12mm-BST-Explorer-ED-Eyepiece.html (167x)

    The Moon and planets show considerable detail at 167x.

    You might wonder as to why Schmidts are not equipped with 2" visual-backs there at the factory, when they're new.  The reason is simple...

    58ed62d6876cf_8Schmidtprimary.jpg.1c1d1ab2c454d860c50aba80c8a86fb2.jpg  

    The hole in the center of a 200mm Schmidt's primary mirror, and through which the light from the object passes, is not 2" in diameter.  It's more like 1.5", and ample for the 1.25" format.  The inside of a Schmidt-Cassegrain...

    sct_scope.jpg

    But given that extra 0.25" of the hole's diameter, 2" eyepieces can be used to make use of that extra bit, and for the lowest powers and the widest views that 2" oculars can provide with the design.  You won't get the full view of a 2", like you would with a Newtonian or refractor, but you will get more than what a 1.25" 32mm or 40mm ocular can provide, and even lower powers in addition.  It's a compromise, and simply to make a Schmidt more versatile.  As a Schmidt comes from the factory, it is primarily configured for the moderate-to-high powers, and with the 1.25" format.  I think that many users simply stick with the 1.25" format, aside from the more adventurous.

    Thanks Alan...

    Kind of none the wiser of which I need to buy LoL...

    Think I need to measure the eye piece aperture and check if it has a screw attachment too before ordering.

    You are all GREAT!

    Cheers

     Can't see that anyone has confirmed that you need either a SCT diagonal, that is one with a screw on attachment to attach to the LX90 or a screw on tube that allows a non SCT diagonal to be fitted. As I recall, the LX90 only comes with one that takes a1 1/4 pushfit diagonal. I think we used a William Optics tube, I had a Nexstar 8se and used the dedicated 2inch diagonal. Both solutions worked well. I preferred the dedicated diagonal because I was short of distance between the rear of the scope. There was a danger the diagonal would fit the mount, thus wrecking alignment.

    Anne

     

    Thanks Anne. I was literally just about to order the diagonal.... I'll wait off and wait till home after work to check the scope.. 

    Appreciate your input.

    So basically I need to check that the eye tube bit as a screw attachment and need to measure the tube bit too?

    Thank you..

    An 8mm eyepiece is going to give too high a power for most sky conditions, a 12mm one would see more use.   :icon_biggrin:

    Assume this would be a decent first buy? Or other poster has suggested 25mm, 15mm and 8mm options..

     

    The 12mm will allow for a close view of the moon but will it also be useful for planets? Or would I also need to buy an 8mm option too?

    Meade always supplys an inexpensive 90° prism-diagonal with the LX90's - has for years. As well as a 26mm Plössl eyepiece. I'd suggest getting a 2" star-diagonal. These will come with a 1.25" adapter so you can use both 2" and 1.25" eyepieces.

    Until you've had the scope cooled for about an hour in the outside air, and you've focused outdoors on a distant object/building/etc - I'd not be worried about collimation. It's pretty hard to knock these telescopes out of collimation. Like dropping it down a flight of stairs.

    Until you find out what sort of objects 'up there' interest you the most, I'd hold off on any expensive eyepieces - though your scope is quite worthy of top-end ones - and maybe look at some used eyepieces for now. These can be re-sold for about what you pay for them, and they'd help you learn about your preferences.

    Have fun -

That is assuming you're in Alt/Azimuth mode and not using a wedge, check your autostar is correctly configured for that. If it's set to polar and you're not using a wedge you'll run into all kinds of problems.

    Focusing can be tricky to do well at first and on some nights if the seeing is poor you'll never really feel like anything is in focus.

    Dew Shield

    The earlier post about a dew shield, do not ignore that advice. Get an inexpensive 8" flexi shield which should be around £25 (or search the forums for examples of people building their own), it's invaluable.

    SCTs will collect dew like there's no tomorrow and once it sets in, that's it, you're done for the night as you can't just wipe it off and even if you heat it to evaporate, prevention is better than cure as deposits can build up on the corrector plate.

    I as I imagine most others do, use a dew shield + heater strip. You can avoid the cost of a heater strip for a while, but I would buy a dew shield before anything else, although I'd also consider picking up a star diagonal as well, your back will thank you on that one :)

    A first scope is quite the learning curve as you'll be unsure if issues are you or the scope at first. The comment about heading to a astro meetup is a good one. Other than that, try not to get frustrated, a bit of patience and persistence and it'll eventually become second nature and you'll wonder why you ever struggled :)

    Thank you Hicks.. star diagonal on order..

    When doing the 'Star-Test' for collimation, a magnitude 2.0 star is suggested. Polaris (alpha-Ursa Minor) is the best choice - as it won't be moving across the sky by much at all. Start with about 200X and slowly increase untill you have a good view of the difraction-rings (circular-lines around the 'donut')

    P.S. When using a screwdriver near your corrector-plate, keep the scope either level or slightly nose-down - this to protect the corrector when you manage to drop the screwdriver. :p

    Diffraction-Rings

    Thank you Dave.

  16. Another question.. I only have a 26mm eye piece. I assume I need another to view planets? Like a 12.4mm.. would love to view Jupiter and Saturn rings etc.. used the other night and literally saw nothing like I know the telescope is capable of..  if I do need other eye pieces what are your thoughts on a zoom eye piece? 8-30?.. or some thing similar?

    Again thank you all for you help and in out.

  17. Here's my LX90 8".. Got a telrad finder on it but no idea what this does?.. look through it and see nothing.. it has red circular circles inside but can't see how that helps me..

    Also has a view finder on the left side... Again.. no idea how this is supposed to help me.. best way ive found to align things is just guess work of using my own eyes and aligning as best I can..

    I assume there's a logbook earlier way ?

    Thanks all for the help, advise and encouragment.

    Jim
