  1. The equatorial mount will allow you track any object, and manually with the RA slow-motion control knob. If you ever want to cause an object to stand still there in the eyepiece, as if time itself had stopped, you can motorise the mount. That refractor is a keeper; and one that you'll never grow tired of, especially as it can easily travel with you, short or long distances, but you'd probably want an alt-azimuth, a travelling mount, for those times. Congratulations., and enjoy.
  2. It's marginally better, at least, than the Zennox variant that you had inquired about previously, particularly in so far as the tripod. Both will have spherical primary-mirrors, and should perform well at that longer focal-length.
  3. The leg assemblies are now ready to be dyed; and yes, the brass is quite flat and conformative to the wooden surfaces...
  4. On the flip side of those overlays, the brass, but the edges of the wood must be dyed first, as there'll be no dyeing where that epoxy touches; same with wood-glue, but I didn't want to dye around the maple overlays, as the glue might not hold in that instance. Why take the chance. I cut the dye, half to half, with denatured-alcohol, and it's still a bit dark... I may use two parts of the alcohol to one of the dye, but I'll need to test that first.
  5. I did the last three in one fell swoop, whatever a fell swoop is. Now, those overlays are lighter than the legs, and I want them inconspicuous, so they'll get a double dose of the dye... Now for epoxying the brass...
  6. Three are not done... ...but three are. You can't rush these things, you know.
  7. The speed, at what gigahertz does the processor, or CPU, run. Online, I'm seeing 1.0 Ghz for that particular model... https://www.amazon.com/Asus-X102BA-Touchscreen-A4-1200-Laptop/dp/B00FAUGFTA Incidentally, Windows 8 came with my Lenovo laptop, but I promptly erased it and installed Windows 7; then later, Windows XP over that. I'm a bit old-school in that sort of thing.
  8. The grain of the maple runs perpendicular to that of the lauan, or meranti, whichever, and for added strength.
  9. After the drilling and cutting-out, you tidy up the rough edges, oft very rough, with a rotary-tool and a small sanding-drum; then sandpaper and steel-wool to smooth and polish, and by hand.
  10. The telescope in question is a 76mm f/4 Newtonian. The design has been around since 1668. This is how it works... ...the light from an object enters the tube and travels all the way down to the big mirror at the bottom. Since the surface of the big mirror is curved, the light of the image begins to form a cone once it leaves that surface. After the light gathered by the big mirror leaves that surface, the light heads back up to the front of the tube, and to the little mirror. By the time the cone of light reaches the little mirror near the front of the tube, the cone is much narrower. The little mirror then sends the tip of the cone of light to the eyepiece, and the image formed to the eye and mind of the observer. Being that the telescope is an f/4, it will require a more precise collimation, the alignment of the mirrors inside the tube in relation to the focusser, and in order to enjoy sharp and pleasing images. Don't automatically assume that the telescope was collimated upon its arrival. Collimation instructions... http://www.astro-baby.com/astrobaby/help/collimation-guide-newtonian-reflector/ https://garyseronik.com/a-beginners-guide-to-collimation/ In addition, the focal-length of the telescope is awfully short, at 300mm. If a barlow did not come with the kit, you might want one if you want to see any details of the objects you're looking at; for example... https://www.365astronomy.com/GSO-2x-Barlow-2-Element-Achromatic-Barlow.html Without a barlow, that 10mm will give you a power of 30x, and rather low; with the 2x-barlow, 60x, yet still a bit low. Now, with a 3x-barlow and the 10mm, you'd get a power of 90x.
  11. Time-consuming, but it is what it is if you want it...
  12. Lovely brass, although not quite as lovely as bronze...
