Last Tuesday I received an update from Tom Benjamin at Tele Vue.

 

The front doublet was indeed slightly decollimated (nice to have it confirmed that I was not imagining it lol.gif ). 

 

He said otherwise it looked good and will give everything (including the focuser) a check. 

 

Tom said the rear doublet was pretty immobile. I then asked him about why they "sealed" the collimation screws to discourage end-user collimation. He told me it was a bit more involved than a regular refractor. As I was driving at the time I can't recall the fine details. I was not entirely satisfied with the answer, perhaps will call to revisit that after the scope comes back.

 

So this new moon window is probably gone too, but I will be looking forward to the winter constellations.

Tom cleaned and collimated my NP101, after cleaning some fungus off the rear cell.

 

It is perfect now.

Whoa. Was there anything unique about the storage conditions that put your lens at risk for fungus?

Probably.  It is the way I got it.  There was no damage, and since cleaning, the optics look new.

For the price paid, I would ask for the screws not to be epoxy glued again.

Can someone post an image of the epoxy? Want to clarify where it is and how to identify it.

 

Thank you...

I have an NP-101is.  Great scope.  I took mine out of the clam shell and put it in standard rings.  I mount it on a DM6 and Avalon T-Pod 110 tripod.

 

Always in collimation, always flat fields.  The only defects I see are in some of the eyepieces I put in it.  Ethos and Naglers work very well.

Six weeks and 4,800km after placing my order my scope has arrived.  (It also came with serious spousal eye-rolling and an unexpected snowstorm).

Updated the signature, but cloudy for the next 10 days?

Ethos and Naglers work very well.

 

 

 

Funny thing ... a few hours before I saw the ad for the NP 101, there was a 26 Nagler Type 5 for sale, and I got it.

 

A very nice eyepiece. The optical character of the 31NT5, but without the out-sized mass. I have been using it in my TMB 130 and am quite pleased with it.

Since the NP101is has a very flat field, I prefer eyepieces with very wide fields.  I probably like the Ethos best for my NP101is.  But the ES 100 25 or ES 120 9 aren't bad. grin.gif

Grant, I realize from my own experiences that it can be frustrating and disappointing when something you have been looking forward to gets delayed. But, try to be patient. Much of the Astro market has been impacted by COVID, from supply to manufacturing to shipping. Televue has been impacted like most. If you check the retailers, you will find quite a few popular items are out of stock and on back order. The ability of suppliers to get materials and products to them is very unpredictable. As an owner of an NP-101 myself, I'm sure in the end that your wait will have been worth it.  Best. Alan

TeleVue was bang on with their estimation of delivery time to my astronomy store and the scope arrived here a total of 6 weeks after placing my order.  Even in pre Covid days I would be happy with that turn around.

Sounds about right.

 

My NP101 arrived back from servicing yesterday. Shipped to them on October 7, making a round-trip time of 44 days. That includes 7 days in transit both ways. 

 

Hopefully find some time tomorrow to put the Cheshire to it.
