For Sale: Orion 6″ Dobsonian telescope and Meade ETX Tripod

The Dob is in great shape, i’ve tried to be careful with it. The mirror could probably use a good cleaning. but it’s clear and aligned. I upgraded the Altitude and Azimuth to make it smoother to operate. I put skate bearings in the altitude so its smooth as butter but not loose, and a lazy susan under the base for a really smooth azimuth travel. Other than that it’s a stock Orion Skyquest xt6. I have a 25mm Plossol eyepiece with it, too. I’m looking to get $175.00 for it. They’re $300.00 brand new so i don’t think it’s too much to ask. 
The tripod(884) is for a Meade ETX 80-125mm scope. It’s in excellent shape and I have the original soft case that came with it. I’m looking for $150.00 for it.
I’m mildly flexible on the prices. I live in jacksonville and work in little rock so i’m looking for someone local so i don’t have to do any shipping.
You can contact me at timothy_brent@yahoo.com.
Thank you for looking, Brent.

SOLD!: Orion Starshoot G3 (one shot color), deep space imaging camera.

SOLD!

walters g3 image2 walter g3 image1

Orion Starshoot G3 (one shot color), deep space imaging camera.
Retails for $420.  Asking $250 or best offer.
Bought this new in May 2015; now only 6 months old.   I upgraded to a bigger camera (QHY8L).
The G3 would make a great gift for an astronomer interested in cheaply getting started in Astrophotography.
Camera fits both 2″ or 1.25″ focuser or extender tubes.
I’ve been able to get great shots with this camera, up to 10 minute exposures, though I’m confident you could go longer with good alignment.
Here is a link to my astrobin page where you can see the kind of shots I’ve been able to get with this camera.  The latest 2 images I just posted are from my QHY camera.  All others were taken using the Starshoot G3.

This package includes:

  • a 12v AC power adapter (10′ long) plugs into standard AC outlet, used to power the cooling fan.  It will cool the camera to about -10 C below ambient.
  • USB 2.0 data cable. Gray 6′ long.
  • Rubber end cap. Keeps the dust out and good for taking your dark and bias library.

Does not include the original box.
Free download of the Orion software from their website to do captures.  Though I highly recommend paying for Nebulosity (about $100) and using it for capture.  I have only been able to debayer my images (convert from RAW to color) using the original Orion camera studio or Nebulosity.

I was never able to get debayering working with either Deep Sky Stacker or PixInsight. Once I switched to using Sequence Gen Pro for capture, I just had problems getting this G3 camera to debayer my images.  I’ve also seen MaximDL debayer just fine, though I’ve never used it.
This camera is in near-perfect condition.  Never been dropped, always handled with great care. Always capped when not in use, and stored in my camera bag at room temperature.
This camera produces very low heat, and weighs only 16 oz.  Includes a guider port if you should ever want to use it as a guider.  Chip size is 1/2 inch which is a bit small for me.  So with my scope (80mm) I had to stay away from bigger objects like andromeda and pleiades.  But your telescope may give you a different crop factor than mine.

I recommend getting your scope info, take my camera specs, and plug them into a planetarium software to get an idea of what your field of view would be like with this camera.  This will dictate a lot of the shots you’ll be able to take without doing something complex like a mosaic.

 

SOLD! For Sale: Almost New Celestron AVX Mount

I bought this mount new in May 2015 to replace my aging ASGT mount.  The AVX is a significant improvement on that mount. See my first impressions of the mount here (http://jamesdixon.us/celestron-advanced-vx-mount-first-impressions/). The mount has performed well these six months so why am I selling?  I got the upgrade fever and replaced my long serving C8 with a C9.25.  The 9.25” is 50% heavier than the 8”.  This mount is rated for a 30 lb payload for visual work and it has handled the 20 lb C9.25 fine for visual but I am now doing photography again and 20 lbs not counting the camera itself is too much for photography. The mount did handle the lighter C8 for photography successfully so I’d say its limit for photography is between 15 & 20 lbs.
Follow this link (http://www.celestron.com/browse-shop/astronomy/mounts-and-tripods/advanced-vx-mount) to see Celestron’s page about this mount.
The AVX mount sells for $799 new, I am asking $600 plus shipping if needed. I will deliver it within a couple hours drive of Little Rock.
If you are finding your Orion SkyView Pro or Celestron Omni GEM to be under powered for your scope this is the mount for you.  Those two mounts are rated at 20 pounds while this has a 50% greater capacity.
Included in the sale are the following:
  • The mount of course.
  • The original foam packaging for the mount head.
  • The 12 lb counterweight. You can see from one of the pictures that this was enough to balance the C8 without anything else.
  • Not only the DC power cord that is standard equipment but an AC power supply as well.
  • The instructional manual and a CD.
This does not have a polar alignment scope, I didn’t buy one with the mount.
The mount came with a 2 year warranty. I don’t know if that is transferrable or not but if so it will be under warranty until April 2017.
