I assume Im not the only one who has purchased astro gear that ended up in the 'not suitable' basket... and subsequently on Ebay etc...
Was a good idea at the time ???? DUH !
The intention of this thread is not to bag any particular product or manufacturer but, given the enormous amount of gear available some of it...well...just doesn't give you warm fuzzies or live up to your expectations for one reason or another...
I guess its the 'money wasted' category....
I will start off..
60mm el cheapo refractor....Shocking quality but at least it started the astro bug

Its been in the box for 2 years and I doubt Id get $20 for it..
Due to my inexperience I somehow ended up with a totally unusable 4mm Meade eyepiece off Ebay.... Completely unusable in my 8" dob ...The eye relief is zilch...
A collection of colour filters....I use 1 of the 8 I bought... Well I did a few times...
A 2 metre length of sonotube that never made it to a home made dob and 2 spiders....
Who else has some items that they wish they had never bought and why ???
