Вот здесь разговаривают про 2" диагональ (надеюсь на данном телескопе
), но при замене на 2х скоростной фокусёр (Сатурн видели). Перевод гугла в помощь если что.

Errol, You mentioned subbing the original 1.25" focuser for a 2" GSO Dual speed focuser. Did you have to re-collimate? How did you do it?

Hello Tangler, no I did not have to re-collimate. All I did was unscrew the three screws, remove and replace. Actually the three screws will automatically set the new 2"replacement focuser in place perfectly.
Here is the improvement with a two inch focuser.
Viewing Saturn with my most powerful eyepiece will keep Saturn longer in focus than if you were using the 1.25" focuser.
What I do is let Saturn come into view e.g. if I get it form my left side I start to view Saturn from a corner of the eyepiece and let it move across the eyepiece.
That way I get a few seconds extra without adjusting the slow motion controls.
Before that when using the 1.25" focuser I did not have that pleasure.
I had to constantly move the focuser with both slow motion controls to keep it in focus. If you ever viewed Saturn from a Telescope before you'd know how fast it comes out of focus.
I use Saturn as an example because it's one of the most difficult planet to keep into focus with a 102mm Telescope.

Thanks! The original focuser has a built-in base for the finderscope. The new GSO dual speed does not have one. How did you add a finderscope onto the telescope tube? I'm not crazy about drilling holes onto the tube.

If or when you buy the "GSO 2" Crayford Focuser - Dual Speed" there are screws located on the Crayford Focuser both left and right, choice is yours.
You'll first need to buy this item from Agena Astro;
https://agenaastro.com/agena-finder-mounting-base-for-crayford-focusers.htmlThe name of the item to use; Agena Synta/Vixen Style Dovetail Mounting Base/Shoe for Finders - M4 Screw for GSO Crayford Focuser
You'll get the above mentioned item and remove any of the desired screw on the Crayford Focuser and attach this Vixen Style Dovetail Mounting Base with a screw included in the package.
You won't have to drill any holes on the Tube. I myself was not crazy about the idea too. So I did my research and that's how I got both items at once.

Привет tobit100, если вы можете позволить себе лучший и больший размер, я бы порекомендовал вам пойти по этому пути. Но если это то, что вы можете себе позволить, то это размер для вас. Все три окуляра, которые поставлялись с прицелом, все 1,25 ". Я связался с Мид и спросил их, можно ли снять адаптер 1,25 и установить диагональ 2", и они сказали нет. Но я позволю себе не согласиться с этим, поскольку я сейчас модернизировал этот же телескоп, и он может использовать диагональ 2 ". С диагональю 2" просмотр намного удобнее, чем при использовании диагонали 1,25 ", входящей в комплект Scope.
