Product Description
This high quality 90-degree multicoated mirror diagonal allows you to take advantage of the wider field of view provided by 2" eyepieces. A much higher quality than standard diagonals, it fits all rear cells of Schmidt-Cassegrains (comes standard with CGE 1400). Includes an adapter to accept 1 1/4" eyepieces and an adapter to use with refractor telescopes.

Andy- it was about US$2100 for everything. Fortunately I found a seller (Adorama) that was offering free shipping, plus Celestron has been offering $300 off the CGEM models lately.
I personally don't like diagonal tiles…maybe you can do subway tiles across and then make a square border with diagonal in tiles of slightly different colour within the square.
Answer for your Question lies in Pythagoren theorem. Please ref the link.
if a and b are adjescent sides of a rectangle and c is diagonal
a^2 + b^2 = c^2
so c (diagonal ) is square root of (a^2 + b^2)
for the given problem answer is
c = Square root of (9+25) = 5.83.

I'd keep 150 mm over 95 mm every time. It should show you objects a full magnitude dimmer. It ought to be noticeable. I've not used the Vixen, and haven't yet been sold on the Maksutov design.
Which one has the more stable mount?

U eva look urself n da mirror n say "Damn I'm one sexy moufucker" if not, u should..good for ur self esteem #imjustsayin
I guess you would really have to have someone else look at you in a mirror, then at a photo of you, then at you directly to really answer this. After all, your Q? is how do "others" see you.
I’ve been told I look like Pai Mei.

Very few 4mm eyepieces are that useful. I have had a Celestron 114GT scope for 6 years. With very careful alignment of its optics, I can use it at 300X with a 3mm effective eye lens (a 9mm quality lens with 3X barlow by Tele Vue). I use that combination because of the longer eye relief of the 9mm. There is practically none below 6mm.
It is rare that I can see any better details because of air currents. The 114GT is 4-1/4 diameter short focal length spherical mirror and 2X internal barlow lens, which gives a maximum of about 250x if carefully adjusted. Trying to use a 4mm on it will not give you very fine details if all conditions are not perfect.
You have dirty power. If there's a Circuit City (if still in business around your area) or a Best Buy, go buy a Monster Power surge protector. They will range anywhere from 150 – 400 dollars. Preferably get one around mid 200s. Yes they are expensive as hell, but they give you clean power, also they will protect from all surges. If any surge does reach your tv, despite what Monster protector you get, they back up all their products with a set amount of money, some even 10,000 dollars.

After Texas crash, a debate on terror threat of small planes
Washington Post
By AP GEORGETOWN, TEX. — After the attacks of Sept. 11, 2001, cockpit doors were sealed, air marshals were added and airport searches became more aggressive, all to make sure airliners could never again be used as weapons. Yet little has been done to …

“You can’t generate information from nothing. Compression based on sparsity seems to be making assumptions about the level of detail in a picture. If you stored 20% of the pixels in Obama’s face you may miss a spot of acne.
I can’t imagine trusting to this technique for pictures of the galaxy. After spending a bazillion dollars on a space telescope we aren’t going to “throw away 80% of the pixels”.
– I’m not certain of this deduction. Can somebody with more background confirm or deny?”

Long answer to this, but the short version is, a reflector like a C8 has more light gathering power and so it’s great for deep space objects. It brings out the faint fuzzies. The refractor is great because it produces a more contrasty image. No central obstruction form a secondary mirror is one factor that helps a refractor. The C8 has a narrower field of view so not so great for deep space photography. Refractor has much wider field of view. Reflector good for planetary, refractor not so good.
how bout some mortal kombat? FATALITY!
the earth’s atmosphere create a blue edge cuz the light is going through AIR, like a little bit cromatic abberration

A Rosarno gli italiani sparano contro i lavoratori stranieri. È una tragedia non solo per chi vive direttamente questi fatti, ma per il Paese: perdiamo la capacità di vivere insieme, di comprendere i problemi degli altri, di rispettare le diversità, i diritti, i nostri valori. Guglielmo Epifani, leader della Cgil, commenta amaramente le notizie che arrivano dalla Calabria. Si aspettava questa esplosione di violenza? «Purtroppo è la conferma di una situazione molto grave che noi avevamo denunciato. Questo dramma è la somma di più elementi. Primo: un insostenibile assetto legislativo, la Bossi-Fini, in cui oggi è più facile restare clandestino che essere regolarizzati. Secondo: le condizioni di vita insostenibili in cui sono costretti i lavoratori migranti nelle campagne del Sud, questo è schiavismo. Terzo: il caso di Rosarno dimostra l’assenza di una volontà politica di risolvere i problemi,si lasciano scoppiare piuttosto che affrontarli quando sarebbe più facile». Il ministro Maroni…
I’m gunna screen shot this and put it on failblog, hopefully you’ll re-read it and realize how stupid you sound.
the movie is autobiographical. the poster is just pointing out where we are on the timeline.
In a plane mirror (flat mirror), a parallel beam of light changes its direction as a whole, while still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). There are also concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror. Lastly, there are convex mirrors, where a parallel beam becomes divergent, with the rays appearing to diverge from a common intersection "behind" the mirror. Spherical concave and convex mirrors do not focus parallel rays to a single point due to spherical aberration. However, the ideal of focusing to a point is a commonly-used approximation. Parabolic reflectors resolve this, allowing incoming parallel rays (for example, light from a distant star) to be focused to a small spot; almost an ideal point. Parabolic reflectors are not suitable for imaging nearby objects because the light rays are not parallel.
A beam of light reflects off a mirror at an angle of reflection that is equal to its angle of incidence (if the size of a mirror is much larger than the wavelength of light). That is, if the beam of light is shining on a mirror's surface at a 30° angle from vertical, then it reflects from the point of incidence at a 30° angle from vertical in the opposite direction.
