5" Newtonian

Posted By Robert Guzauskas
This may fall into the category of, "An idle mind is the Devil's workshop" but...

I have a Meade 4.5" f8 reflector. It's accessories aren't worthy of the name. It's on a GEM2 aluminum tripod that wiggles 'n waggles in my gentle hands. But in spite of these short comings I use it often because it's light and available. Now here's my thought: A 5", 750mm mirror will fit in the same tube and probably the same cell. I have better accessories at hand. I have a lathe and vertical mill to refit the GEM2 with larger shafts and some bearings...

But am I trying to make a silk purse out of a sow's ear? I have an 8" f5 reflector so I don't want to clone that. Are there any sane minds on this Forum that might counsel this madman? What say you?

CGE conversion

Posted By Robert Guzauskas
I have aluminum castings for a pier mounted GE with 1" shafts - formerly steel shafts, now aluminum. I have a new 8" Celestron Newtonian OTA.

My Question is: Where might I get a "GoTo" or "DSC" add-on to drive this rig??

Meade Starfinder & Polar alignment

Posted By Robert Guzauskas
I have the Meade Starfinder (portable) pier mount for my 8" reflector. Can anyone advise me on: 1) The leveling of this portable pier; 2) the Polar Alignment of the RA axis.

How can I level and align my Starfinder?

Cobble an Autostar??

Posted By Robert Guzauskas
I have a (new) Meade 493 kit that contains two motors, gears, mounts, and, a Meade 497 Autostar hand held computer - all apparently intended for some Meade Alt-Az ETX mount.

But can this hardware be used on a GEM mount? Or, can a GEM mount be fooled into thinking it's an Alt-Az mount? ...Help!

Apeture & "f " stops

Posted By Robert Guzauskas
I have a new 8" Celestron Advanced Series Newtonian. It's an f5 scope. I'm lusting for a Meade SN 10". That's Meade's corrected, f4, 10" Newtonian.

Would I see any significant difference in photos taken with one or the other?

Celestron Schmidt Newtonian??

Posted By Robert Guzauskas
Has anyone knowledge of a Celestron Schmidt Newtonian reflector telescope? One model may have had a 5.5 inch apeture and about 500 mm focal length. An f3.6 ratio. Any historians out there?

Are there any historians on ASTROMART?

Tidal flows

Posted By Robert Guzauskas
I moved to Florida 33 years ago because I love to fish. And the successful fisher-person pays close attention to the ebb and flow of the ocean tides. The experienced boater would note that tidal flow is one of the most powerful forces of the sea.

OK astronomers if the water of the oceans is subject to gravitational tides - does the atmosphere of our earth, or any planet, exhibit a similar, periodic, tidal ebb and flow.

What say you?

CG-5 and a killer DSC

Posted By Robert Guzauskas
The acronyms mean I have my 8" Newtonian on a new Celestron CG-5 mount. I don't want a GoTo system but I do want and need some help locating DSO's.

So which is the killer DSC system for my Celestron CG-5 setup? Ease of use and dependability are mission critical.
