My location just North of Manchester is a crossing point for the two major UK flight corridors, so my seeing is not great 🤷🏻 Having tried all the major types of telescopes I find refractors work best in this location. I live within the Manchester terminal control area 😱

Are you going to use it to find another Tak to add to the collection ? 🙂

@Flame Nebula The trick to getting the best out of a closed tube telescope is to minimise the temperature difference between the optics, the interior air temperature and the exterior air temperature. Waiting for the scope to come into thermal equilibrium is one way to do this. Another way is to wrap the scope with two layers of Reflectix from B&Q, this essentially minimises the temperature gradient between the outside air and internal air in the scope giving internal stability. You will be able to use your scope immediately and an added bonus is the corrector takes much longer to dew up as the air inside the scope stays warm longer.

Brilliant 👍

Hello @Wanderers (Andy) and welcome to SGL. Do you want to do do visual astronomy as well as photography and what do you want to photograph ? Also what is your budget ? We can help more if we know the above and we are always keen to spend someone else’s money 👍🤣

How can you live with that blue circle ? 😱🤣

Nothing to gain optically over the Everbright, except the Blue 🤣 But I wonder what Takahashi Jezzer thinks 🤔

One day you may decide to sell your Tak and those rings may put people off. I suspect the lens spacing may be different to other FC100’s that do not show the rings. If that was my telescope I would be talking to the vendor.

I think this is what you are seeing… https://www.cloudynights.com/topic/679457-newton-rings/#:~:text=Newton's rings are most commonly,spaces between R2 and R3.

That looks like Newtons rings but I don’t see those on my Tak FC100DZ

x220 will be good for Mars 👍

Welcome to SGL Dave 👍

@Alan White I used to have the 8.5” version of your scope which I bought in 1985. I still remember taking it out one night in the 90’s after midnight to look at Jupiter and the detail was utterly staggering. I have had many scopes since then but none have blown me away in the same way as the Astro Systems 8.5 did. David Hinds, Rob Miller and @Peter Drew really knew what they were doing 👍 So it’s definitely worth fixing your scope up.

Those Naglers make all the difference 🤣

Maybe a 75mm 🤣🤣🤣

This 👍

Nope, my telescope buying days are over 🤣

Good try but 100mm is as low as I go 🙂

The TSA is shorter, lighter and more expensive 🤣 The FS showed more vibrant colours when viewing the planets and doubles, which I liked. The TSA is better corrected for colour and planetary views are cooler looking than in the FS. Cool down time is the same for both.

The TSA102 and FS128 have gone to new homes leaving the TSA120 which I plan to wear out from overuse 👍 Then when I’m old and decrepit I will start using the FC100 🙂

There is nothing like a good refractor… Or two…🙂 Or three…😁 Or four…😆

@Grump Martian You may be right. I had a silver 6” Nexstar evolution and the Baader SCT visual back securing thread was too narrow so it would not tighten up BUT that was the non clicklock version I think.

Freudian slip ?

I just keep buying white refractors - they all look the same to the wife

Are you making a binoscope ?
