Hello,
Is a 2" eyepiece holder better than a 1.25" one?
Would it be convenient to use a fan for the primary on the 10"?
And since it would be used manually, what would you recommend as a search engine, an optical one, a laser, a red dot...any other?
Thank you so much
Tico

Hello, 

I'm Looking for information on one Dobson 10", in your opinión what model can be a good 10"? 

Thank you

Hello, 

How to search double stars in this mount? 

Thank you. 

Tico

Hello, 

Anyone know some atlas or book for double star visual observations? 

I think that for my mount one large, but small aperture, telescope can be very bad!! 

Well.. 

Thank you all advices!! 

I've one photo-tripod and panhead 501 Manfrotto, also one Nexstar SE Goto mount, and Yes, I'm looking small telescope. 

Then, this Maksutov best  than one refractor? 

400 or 500 euro.

How is this for the double Star? 

Best R.

.. But on the other hand I think that those with 90° eyepieces are much better in terms of comfort for astronomical observation, as in any telescope we use, especially for zenith observations. , which is when the objects are best seen... the higher I mean!
Have any of you been able to compare 90° with 45°?
On the other hand, I already have some straight Opticron 15x70 that are good for terrestrial or not very tall raptors...
As for collimation, does either of them, 45° or 90°, have any advantages?
I mean, does one decollate more than the other, for example?
Best regards,
Tico

Hello, I know that any telescope is valid for observing doubles, visually speaking, but in your opinions could you advise me on a model that is especially adapted to this type of observations? I'm not looking for the latest in lenses or mirrors... no, but rather some manageable telescope but in which these marvelous objects can be seen well. Thank you Tico

I'm Looking this BT binoculars for astronomical use, but not only but planespotting, bird watch in sea, lake... Terrestrial. 

But will I really and honestly be able to see the difference in the image between a 15x70 straight binocular, like the one I use, an achromatic Opticron, and one with a 45° or 90° 70mm binocular with the same magnification? And in this case I am not referring to the comfort of the neck but rather differences in the image...
I ask because there is a big difference in price.
Tico

I think that it's the Standard BT 82 XL of Explore Scientific.. 

Thank you very much for your kind answer.
Out of curiosity, what models and brand do you have?
I imagine there will be a big difference between the 100 and the 70...!!
Did they have the eyepieces at 45° or 90°, in your opinion which of them works more comfortably for astronomical observation?
For a place with some light pollution, how do they work?
I have a more or less robust Manfrotto 055 tripod and a Manfrotto 501 head... I am deciding right now between the 82 and the 70... (the 100 seems more cumbersome and heavy for my support) and the balance is opting for the 82..., on the other hand I have an Opticron 15x70 with straight eyepieces. and I use it frequently, I love it even though it is achromatic, but above a certain altitude it is impossible to use it in a thorough and judicious way so as not to break my neck. I use it for astronomy, airplane observation and for land and birds. I like it more than observing with a telescope, it lacks "life" if I can say something like that...
How sharp and contrast are yours? Have you been able to use nebular filters to observe nebulae?
Please excuse me for such a long message.
I thank you very much for your advice, opinion and time spent answering my questions!!
Best regards.

Tico.

I prefer one binocular of 15x70 ir a refractor 70/80 for wide angle, I usé the Pronto Televisión for this purpose. 

I has one Maksutov 90mm but ir it've a field very very small, complicated for To search objects in the Sky with AZ mount. 

Hello,, 

Yes, is true!! 

For example, a Explore Scientific or APM.. 

Hello,
Currently I am looking for some information about the BT-82 XL binocular.
I would use it for deep sky observation at low magnification, and also for terrestrial observation, since to observe planets, for example, I have an SC 8" telescope. In your opinion, how would it work for these purposes?
I have a good Manfrotto photographic tripod and a Manfrotto 501 head to put on it.
You have used it to observe Messier objects, is the image good with sharpness and contrast?
What magnification do you usually use?
thank you so much
Best regards,

Hello, 

I'm looking one small ED refractor, for terrestrial and astronomical ( quick look) observations, for serious observ. I've one SCT 8".

In your opinion which can be a good and light refractor for visual in one photo- tripod mount? 

Thanks in advance.

Hello, 

I've the Lunt 40 b600, really a great solar scope, comparatively with a PSt, very old and a good Lunt 50 b400, I like more the Lunt 40 image, in visual mode, why? 

I Don't Know!! 

All above is my humble and personal opinión!! 

Thanks, 

Tico

Hello, 

Anyone know It the Bresser Astro 10x50 individual focus is the same than the LightQuest 10x50? 

Thanks

Tico

Also for birding... 

The APM 10x50ED is good for DSO, Nébula and wide angle vistas? And I Don't use spectacles for observing... 

Thanks,
