For the price, is a 11 or 14 inch sct telescope a dramatic improvement from an 8 inch? - sct telescopes
What I mean is that really worth the difference of $ 4000 - $ 5000?

Sct Telescopes For The Price, Is A 11 Or 14 Inch Sct Telescope A Dramatic Improvement From An 8 Inch?

Sorry, but there is a significant difference between 8 "and 11" opening and 14 "is even greater.
"Compared with an 8" mirror is the alignment of the light gathering power) on TBS open space (including the necessary deductions due to the increased secondary mirror: 9.25 "= 1.35 x 10" x = 1.6, 11 "= 1.9 x 12 "= 2.3 x 14;" = 3X and 16 "= 4.2 x. Than 11 "mirror that doubles the capacity of the collection account of an 8" mirror and still be manageable in terms of weight (depending) on the strength of the owner, 11 "multinationals are becoming extremely popular." (See Appendix).
The view from my 10 "SCT differs radically from 8" areas that I looked around, than to 12, 14, 16 or even 20 and 24 in opposition "areas. Abertura bottom line is king, and no significant improvement with each 2 "of the opening is has on the diameter of the primary mirror.
If you want the money for the 14 "issue and get the 14".
Some other issues that tto examine or TBS. The 11 "will be much easier to handle if he wants to create a major turnaround. Verse 14," which will assemble the kind of result you want to dock and leave the configuration of an observatory for the house. All depends on when the arms of steel "o lift Smokin '" and then each night of observation. As the time of installation will increase from approximately minute 30 seconds (with an 8 "Date of birth 20 to 30 with an installation (TBS, leveling and alignment), but with the new GPS enhanced the adjustment process has been significantly reduced.
The following article explains the differences.
-Edit-Tina is a good starting point, dealing with weapons of steel "Smokin 'o' take 'position. Celestron has reduced the weight of the SCT OTA (Optical Tube Assembly) Carbon. However, the weight of the ice is still very important. My 10 "Meade LX-200 (aircraft-grade aluminum OTA) is 60 lbs. I choose a forearm and arm curl curl t/ In the corner of 60 pounds / tripod. INSTALLATION TOTAL s my weight 120 pounds. There are better ways to limit this. Many of our club members have climbed Dobson's Armor (which I am sure that they draw Tina - (although I never met Tina is or scope)) The mirror can be fitted in a tip that wheel. With a design that can easily 14, 16, handle 20, and up to 24 "areas of the field observation. SCT, while 24" is not in the field the problem.
No
On this scale, the differences between the diameter of the telescope is marginal. I'm getting the 11inch and save money so that you can buy some useful gadgets that go with it, such as sunscreen, a Barlow lens and perhaps a comfortable chair for cold nights!
We hope you enjoy watching:)
EDIT: As I said I was talking about marginal differences to the casual observer assumed that I was asked the question.
Of course there are differences in the technical aspects that you mentioned, so the price difference. I think that 11inch is a better option for someone looking for a superficial view, the money saved could be an ingenious use of the purchase of other products, for example, the user may be allowed, plunge into astrophotography.
A 11 is more susceptible to resolution by 38%, and 1.89-fold in the collection of light from an 8 "or 14" is more susceptible to resolution by 75% and 3 times the light gathering of an 8 "
This is important. Only you can decide whether it's worth it.
The other thing to consider is the portability. The volume is extremely portable, while an 8 "is very portable.
Edit: I should add that there is a 12 "SCT years. I was very pleased with how they could use, because he could not install itself to be disappointed. This is not just the weight, the biggest and the awkwardness of the telescope a problem.
I also agree with the concept of Dobson. However, the ability to read the SCT very pleasant. As is his ability to be easily operated with a ruler.
Edit again: I'm sorry, with all due respect, the 14 "Celestron is 243 pounds or 110 pounds. It is too difficult for most people to handle. This is a permanent mount scope, this is not a car enthusiast to buy one application could be an 8 "or even 11th
Oh, and PS, what is wrong with my answer, you gave me a thumbs down? Write a comment and not just a thumbs down to an answer to a question. Idiot.
They do not look very hard. These are the standard fields that are used by thousands of astronomers.
I have a c14 awarded under a dark sky in New Mexico and found it, but I had to configure. How strong are you? these things are hard *. *
How is your heaven? There is little importance in the hole, if you have a crummy sky.
Why TBS, btw? Dobs are cheaper and much easier to live with these sizes. I gave birth to a 18 "Armor and only takes 10 minutes to unload my car and lifted him up. It's really cool.
later, my date of birth is dealt with more than 18 "the obsession of the wheelbarrow. casual. pleasant to use. balance the load and moves very well with your finger, it stays where you point, and it's solid as a rock. Equatorial - Wall to as large an area would be the basis of an observatory ...
People do not tend to be GOTO in Dobs, but push-to-digital media-setting works well and is highly recommended.
