Hey all.

I am just curious to know...What separates the Lacertas from other newtonians? I have heard the main changes are-

1.A better tube

2.Good flocking

3.Octo60 focuser

Please point out to me anything I have missed out on.

But the mirror remains the same one from skywatcher...It is true that Lacerta Photonewtons are upgraded skywatcher quattros.

So-If I got an Astro-Tech(I think a rebranded GSO newt-Am I correct?) newtonian and upgraded the focuser, upgraded the tube with a good carbon fiber one, baffled and flocked the tube with Black 3.0 and did some other modifications like replacing the secondary mirror vanes and holder with Artesky vanes and a holder, and also replaced the primary mirror cell, is it going to perform just about as good as a 8 inch Lacerta Photonewton? Do GSO mirrors perform as well as the skywatcher ones? I have Guan Sheng Optical's mirrors are 1/6th wave-1/12 wave RMS. And how does the Octo60 focuser compare to the other focusers out there(eg.:-Moonlite focusers, Feathertouch focusers).

Thanks for replying in advance!

Ayaan

I think there are a few more benefits, according to the manufacturer, if you look here...

Well, for one, the carbon fiber tubes are made my Klaus Heim.[forgot spelling] which means that they are going to be out of stock forever.

It's Klaus Helmerichs, aka Klaushelmi. Very rigid carbon tubes. As Skywatcher doesn't produce the Quattro carbon tube series anymore, there is a lack of alternatives.

 

Btw., another advantage of Lacertas is that you can order an optical test and collimation service with their scopes.

In the past i think in 2017 the year i started astronomy in general, i came across Astrobin and saw images done by Lacerta, i think i saw images done with two scopes both Newt, one of them is Lacerta, and both giving 1000mm focal length, one is 8" F/5 and the other is 10" F/4, the images or results were enough for me that i decided i want to buy 1000mm FL Newt in the future, i wanted Lacerta but it was so pricey for me, then once day i saw a seller on eBay selling his brand new Meade 8" F/5, wasn't sure about it, but then i said why not buy it and give it a try and see, since i bought it i kept and still keep modifying it, but i won't modify it too much anyway, not trying to reach Lacerta or better quality scope level, but i am happy to have 1000mm focal length scope anyway.

Hi Tareq,

Thanks for the information on your scope!...What modifications have you made to the Meade?

Hi Tareq,

Thanks for the information on your scope!...What modifications have you made to the Meade?

Just little ones, changed the focuser from single speed to dual speed Crayford, changed the collimation screws for both mirrors to Bob's Knobs ones, that's all, i am thinking about changing the primary mirror in future maybe and maybe add a fan if necessary to the rear of the scope, and i have to cover the rear due to light leak, i don't know if i should change the focuser again or not, but i think i won't do that until it is giving issues first.

You can read the skyandtelescope article on how to beat atmospheric seeing if you haven't already. It can help with making the telescope accommodate to the ambient temperature in a more effective way.

Honestly speaking, i don't think i have this issues at all, or let's say it is not my big main issue, with my refractor and lenses i just use dew heater straps/strips and it did the job perfectly, now only Newt, i do have the Mak, but the Mak isn't for DSO anyway, i use it only for moon or planetary and sometimes visual.

 

I still believe in my 8" F/5, it is not in that Lacerta or OrionUK ones, but it can be as good, the main thing is the mirrors, if the mirrors are all the same then whatever else can be modified later, and because i didn't use the scope much yet so i won't give up on mirrors yet.
