Lunt 60 Double Stacke filter arrived - NOT HAPPY

Post by salvo lauricella » Tue Feb 04, 2020 3:05 pm

Hi all, today the Lunt 60 Double Stack filter arrived. I was so excited and soon wanted look with it. I followed the Lunt instructions, first tune the scope in single stack mode (I was able to see some nice filaments and prominences), than I installed the Double Stack filter. I tuned the filter but what I saw was just a red disk without features...I was not able to reach the focus!!! I tried about one hour and nothing changed...When I take off the filter I noticed that there are some sounds inside it...I think they shouldn't be there. So I contacted the shop...probably it is decontacted!
The shop will contact Lunt Europe and I think/hope I will send for the assistance.
So my first experience with Double Stack is painful :cry:

Salvo:
Sad experience, I once had an experience like that with an Ha filter, the air trip decontacted the etalon, due to cold or pressure loss or pressure changes in the cargo bay of the plane.
Best wishes,
Eric.

I also tested one and I was not satisfied. The one I tried was not decontacted but the views were not that great (double-stack LUNT60)

best regards

I can imagine that must have been a big disappointment.

I hope they manage to get that sorted for you asap, so you can finally enjoy the new toy :)

Oh dear! transportation is always a worry. I sent my Solarscope back for a double stack filter and it came back part decontacted. After that I picked it up by hand but that was lucky as he drove it over from the Isle of Man. I don't think you can do that over the pond ;)
Bad luck, I hope you get it sorted soon :(

Goodness that's really bad considering the cost of these filters. Hope you get a new replacement one, I wouldn't want the same one back repaired at those prices.

My 60mm double stack filter’s been excellent - substantially more detail than single stack, though it does take a bit of experimentation with the tilt to get best detail. I’m surprised these filters don’t come over land from Bresser in Germany for European customers. Such expensive and fragile technology.

I am surprised too! Here is an example of what I see when I double stack my Lunt 60.

Hi Salvo,

That is totally unacceptable. Has the vendor or Lunt reacted and offered a solution ?

I had a similar experience las year qith a blind Quantum PE 0.4Å etalon which costs US $ 12,500.00. After a year it was solved and that was sending it back and I got a refund.

Very bad ...

:shock:

Hi Rainer, I am still waiting to send back the filter to the shop (I bought in Italy).

Good luck Salvo - am sure they’ll replace it, but it’s still frustrating that these things always seem to take a long time

Wishing you better luck with the replacement, Salvo. It will be worth the ‘pain’. Just so unnecessary, though.
