I would have thought they had had enough time to get it right by now?

star testing wasnt the best shall we say, i spun the primary and the image didnt alter, so putting it down to the secondary

Morning Mike.

Thought you might've got to the bottom of this by now? I was keeping my fingers crossed for you that the problem was in the secondary which should be an easy fix. 

Hopefully those guy's at Orion will finally get the reflective bit's sorted especially as the season for using it is upon us :dontknow:

Keep us updated as we're all waiting to see the outcome

If that was a rush, I'd hate to see how long it takes them when they take their time :eek: 

Looking forward to comparing results with mine at the weekend (if mine can finally avoid getting dewed up :thumbright:).

hi calv, lets start at the beginning, phoned orion optics last week and spoke to barry and john, told them the problem and they said bring it in, in the holder so we could test it correctly, i said i would providing they have a secondary ready as i need it this weekend coming, i was told by john they have a new batch that will be finished friday gone, so if the fault is with the mirror then its a easy swop. emailed them friday and to be fair they responded quickly and said the mirror is twisted, they are going to remove it from the holder and test again to make sure its not the holder. they removed it and said its still twisted but need to remove the kendrick dew guard to rule that out as well. but havnt heard from them since, sent them 2 emails today and nothing, so will ring tomorrow hope fully to collect it.

 

so bottom line is the secondary is twisted and just need them to replace it easy as that  :crybaby2:

That sounds a bit more positive Mike. A secondary should not be to hard to sort out surely for OO ?. A lot better than hearing that there was a problem with the primary?, otherwise you would be in for one big wait. All the best I hope OOuk get it sorted for you soon buddy?

At least it is something that can be 100% addressed. Hope all gets sorted on time and becomes a distant memory...

before i took it niallk they said they had one so it should be a walk in the park to sort

Hmmmmm it's not looking too good for Elan mate. At least you'll have a great Strehl ratio with no central obstruction! Not much good for observing though :icon_biggrin:
