All astronomical telescopes show upside down and or inverted images-- it's normal nothing is wrong. You are applying too much magnification. Do not use the 2x barlow-- and start practicing how to focus using only the eyepiece with the largest number written on it which is your LOWEST power.
You can practice focusing during the daytime on a distant object like a telephone pole or a building.
First WHY would you use a erecting DIAGONAL in a reflector style telescope. Upside down images are completely normal for an astronomical telescope. You only need this diagonal for terrestrial viewing NOT for star gazing. ALL astronomical telescopes show upside down and or inverted images- it's completely normal.
If you cannot come to focus with the erecting diagonal, it's probably because the diagonal moves the eyepiece too far OUT away from the point where the scope comes to focus. Again-- you do not use those for night time sky viewing. Just stick the eyepiece directly into the focuser.
You are using an erecting diagonal mirror between eyepiece and the scope. This flips the image (normally inverted as you realise) upright, but does not correct the reversal from side to side. These are often supplied with astronomical scopes more for ease of looking through the scope without craning one's neck upwards, rather than for the purpose of erecting the image.
There are other types of erectors that will fully erect the image if it bothers you, but astronomical telescopes normally are used without concern for such conventions, as the erecting lenses or prisms absorb light and introduce aberrations or reflections. If you wish to use the telescope for terrestrial work, you would probably be better off with a "spotting scope" which will be fully corrected for image orientation.
Meade's website has manuals on most of their product - since they make hundreds of styles, an exact manual may not be available - just choose one that is closest. Things are inverted and reversed, as it is an astronomical telescope, and it does not matter what the orientation is when viewing the sky. To get the images part way corrected, use the diagonal mirror before the eyepiece and look in the downward position. images will be correct in the Up/Down direction, but not left/right. That is why binoculars have 2 prisms to correct the image.
Hi, this is a common "problem" for astronomical telescopes. Same with my Meade 3" refractor and spotter. It is actually a design 'feature' not broken.
The issue is that most astronomical telescopes naturally show images upside down, or some combination of upside down and left-right. (Astronomers usually don't care, because space has no up or down.) It is just the way optics work when lenses or mirrors bounce and bend light. (And since the professional astronomer wants the most light and most direct image, they usually don't want extra devices just to make it right-side up.)
Reason that binoculars don't do that , is they employ special internal prisms to get the image back right-side up.
Easiest solution for astronomical telescope is to buy what is called a "star-diagonal" or "image-erector prism". These will usually make the image look normal for us earth-based folks.
I do not know what exact type your Meade 227 telescope is, but the spotter scope is most likely a simple refractor. So it MAY be possible to install a star diagonal onto it. Or might not. Depends on the exact spotter scope design. Another option may be able to buy a replacement spotter scope that is designed for correcting image orientation.
This sounds like a name for an astronomical telescope. I do not own/may have not seen one, but anyway here goes.
Terrestial images do/will appear upside down. This is normal. Just to add to the confusion some telescopes LEFT and RIGHT can be reversed.
First a few Q's & A's
Can you use different eyepieces?
If 'yes' then what is the diameter* where it enters the scope drawtube/foucuser? (the most popular size is 1.25inch the other is .965inch).
You can purchase what is called an "image erecting prism". This should solve your problem. These are available as an accessory from on-line astronomical dealers. Sorry, but I do not how much you will pay.
As there are many telescope manufacturers 'out there', prices do vary. I cannot remember whether Tasco have one made under thier name. If it helps Tasco are owned by Celestron.
