Need help/ opinions...please!!

Hi all,

I just got my Mewlon 250 back after getting it re-colliminated, cleaned and generally back to like new condition. I paid over $600 for this including shipping both ways. Attached are inside focus/outside focus star images shot after the scope had 2 hrs of cooldown. I tried to image Mars, but all I got was mush. I imaged Mars with the TOA-130 and preliminary images are the best I've seen so far. Anyway, do I need to contact the company that did the work and get better?

I assume they would have seen a collimation
error that large. Seems likely it got a
bad bump during return shipping. Perhaps contact
them, explain what you see, and ask for
instructions on how to collimate it yourself?

Hello Paul,

no need to worry (too much)! I know of very few scopes that would hold collimation after experiencing the handling of some freight forwarders. Alas I have never collimated a Mewlon, but I have no doubt that TNR will be able and willing to give you proper instructions on how to do it.
I also suggest to learn how to do it yourself, as it is fundamental to keep collimation at its best to exploit your scope to the max. It is a patience-intensive procedure, but, once you've learned you'll be able to do it in minutes.
I suggest to do it using a webcam, otherwise it will be very painful

Ciao Paul and good luck
Luca

PAUL, YOU NEED TO COLLIMATE WITH TAK. COLLIMATION SCOPE. BRING THE PAINTED CENTER BLACK MARK ON THE SECONDARY IN ALIGNMENT WITH THE COLLIMATION SCOPE'S CENTRE MARK AND THEN STAR TEST AND COLLIMATE THE PRIMARY, I DID THIS MEWLON 300. I HOPE THIS HELPS. MAHESH YADAV
