Hello Peter [Natscher], Hope you are well. An 8 inch Portaball with a Zambuto mirror on a tracking platform is going to show you much more than a mm telescope, even a Starfire EDF.
Both of these will be sit down and observe telescopes. If you were not going to get a tracking platform, I would go the refractor route. You will want tracking for dedicated planetary or lunar observing.
I have the non motorized version and it has a great mirror, however, your mileage may vary on the chinese mirrors. Tony M, from an online thread entitled: The GEM will negate all the disadvantages of the Dob.
My old Meade easily gives me a sharp, detailed Mars at x conditions willing. I may be too late to add my. The Portaball rips the APs to shreds. Especially since the Portaballs are constructed with fans and other ergonomics to help with the thermal adjustment. One should never lean too heavily on sketchers.
Although the vast majority are genuine, some go to an imaging website, study a particular image, and fake a sketch. In this way, they can make a 4 inch peashooter telescope look better than a Hubble image. This is why I believe that the high refelectivity coatings that are now applied to many astronomical mirror surfaces are so important.
A high reflectivity coating is well worth having even at an additional cost; not only will the telescope perform better but a second advantage is that the mirror surface allows far less moisture to penentrate and is likely to last perhaps 25 years before it has to be recoated.
I have a 10 year old Newtonian whose mirror was one of the first to be given a high refelctivity coating and it still looks like new………The overall design of the telescope will affect the overall contrast as well.
It is impossible to beat a well designed refractor, but Newtonian telescopes, where one observes across the tube assembly to the far wall, are almost as good.
The focal length will thus be mm, and the field of view when a low power, wide field, 2 inch eyepiece is used will be approximately 2 degrees.
This is a good compromise, but some manufacturers, such as Orion Optics in the UK allow the purchaser to choose other secondary diameters should he or she wish to optimise the telescope towards planetary approximately 36mm or widefield imaging approximately 60mm.
Furthermore, since the Talmud represents a massive accretion of published commentary built up over more than a millennium, even the most explicit mandates have sometimes been transformed into . The walk to do after enjoying all those dumplings in Monterey Park. Folks may think more about great Chinese food than great walking when they head for Monterey Park.

It is no very good symptom either of nations or individuals, that they deal much in vaticination.
One could even purchase two flats for use depending on the type of observations planned for a given night! For that scope, a fan in a baffle below the primary works fine. Making a good 8 inch Newtonian by Toshimi Taki Japan. I think I can speak with at least a little credibility on this subject, having owned numerous large refractors: Once we started having master mirror makers like Carl Zambuto et.
This scope is fully driven and features GOTO, yet I can set it up, take it down and transport it easily all by myself. Would I love to have a giant TMB set up in a dome behind my house? Mike Harvey Floridafrom an online thread entitled: The inability of the refractor to show much spiral detail in galaxies is probably its greatest drawback as a deep sky instrument.
My advice to everyone wanting better planetary views is is to always spend money on a better instrument, or make their instrument better than it is. Planet Earth, from an online thread entitled: For telescopes up to inch aperture, a curved spider can be a good alternative to traditional 3- or 4-vane spiders.
With larger scopes, the diagonal mirror typically becomes big and heavy enough that the greater rigidity offered by conventional spiders or more robust curved ones may be required. My single-curve spider has the added benefit of being simpler than the ones in the article, and therefore easier to build.
Gary Seronik, from his online article: This is essentially an aesthetic issue. It does eliminate the spikes. You will see an even glow around bright objects like Jupiter or Venus, and nothing around everything else…….
Jarad, from an online thread entitled: IF you were to put a TOP QUALITY mirror in your scope, along with the highest quality diagonal you could find, you would find that on axis, it would indeed take refractor very close in size to yours to give a better visual image at the center of the field.
Ed Moreno, from an online thread entitled:As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria.
Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo. Many thanks to Hermes for the translation from mtb15.com Why the future doesn’t need us.
