Well, I have almost narrowed this choice down to these 2 telescopes (the one that comes with the AVX and the OMNI XLT 150).

If you only look at the OTA, I have hard time deciding which way to go:

The AVX telescope has a smaller secondary mirror, 1.25" focuser, and interesting hex-screws in the back for collimation.
The OMNI XLT has a larger secondary mirror, 2" focuser, traditional colliation screws and XLT coatings.

Why should I pick one over the other for primarily visual - only looking at the OTA?

Eyepieces Questions & Recommendations / Learning curve for using EPs
« on: January 09, 2018, 03:19:53 PM »
I received 13mm ethos yesterday and used it for the first time last night. I was blow away by the "majesty factor" when I can use the EP for few seconds on and off. It was hard for me to see the whole FOV withoout blinking my eyes...

I didn't have an issue with 24mm pan. Since 24mm pan and 13mm ethos have the same eye relief, I figured 15mm eye relief is not bad considering I wear glasses. The difference is the exit pupil. With 2.4mm exit pupil, I can use 24mm pan for hours. With 1.3mm exit pupil, I struggled a little last night.

Any tips on training your body (eyes) to adapt a new eyepiece such as 13mm ethos?

Eyepieces Questions & Recommendations / Meade UWA impressions
« on: December 31, 2017, 06:25:08 PM »
So, these eyepieces appear to be being phased out by Meade, at least some focal lengths are no longer available new, and their price new is very attractive. I figured this was a good time to ask people who own or have owned them for their impressions and cost vs yield compared to other 82 degree eyepieces out there. I have never tried one so I can't begin the thread but I am very curious to hear what you all think. Thanks.

Mounts Questions & Expirience / Used GOTO Mounts for 80mm Refractor
« on: December 31, 2017, 05:36:12 PM »
I have a C80ED, 80mm D, 600mm FL refractor OTA. It's a very nice refractor and I currently use it on a Universal Astronomics light duty mount. Which works nicely.

The OTA weighs a total of 7.5 Lbs.

I often see used Celestron or Meade GOTO mounts offered, working condition, with the included hand control. It's the mount only with a vixen type dovetail, and curved so the scope can reach Zenith. You would attach the mount to your existing tripod and, of course the scope to the dovetail.

Most are listed to have a capacity of 9-10 LBS. They have different costs ranging from about $60 to$100 or so.

It's difficult to find specific objects or ever stars to hop from where I am due to light pollution. So, I'm thinking if I wanted to find Uranus (definitely not naked eye) or an interesting star such as VY Canis Majoris, a mount such as this might help.

Has anyone used one with a similar scope (7.5 Lbs.)? Just wondering how well they may work for such a setup.Thanks!

Jupiter is currently at its closest position this year and the viewing has been spectacular this week.  The seeing has been about the best I have ever experienced. Is this a local thing or is this going on around the USA?  Is this a gulf stream shift or something?I was out with my ETX 125 during the week and seeing was great.

I was out with my Orion XT8i last night and it was even better. I got the best views of Jupiter I have ever had.

I spent most of the observation with the Hyperion 8-24 zoom. At times I had a very sharp image for 2-3, maybe 4 seconds at a time and I could adjust slightly shorter, slightly longer to optimize the image. 200 to 240X were the sweet spots.  Normally I can't view Jupiter over 180X and then it fades in and out constantly.

I could clearly see the GRS in the top band (in my Newtonian) about 1/4 of the planet from the right. By time I was ending the session around 11:30 pm the GRS was about center planet.

I was also able to see more detail in the main clouds then ever before. I could see well defined shading with variations toward the poles. I have never seen this level of detail before in any of my telescopes. And this was at my very light polluted house observing site.

This was absolutely my best observation session on Jupiter ever!

I am on Long Island, near NY City.  Normally the seeing is poor but this week it has been great. My friend has a 14" Orion XX14i and he was able to maintain at 300X last night and could occasionally push to 400X.  Outstanding.

Is everyone enjoying these conditions?Edit. I was using the zoom in a GSO 2" 2X barlow to get to 200-240X.

Reflectors Telescopes Forum / 900mm to 910mm mirror swap question
« on: December 28, 2017, 08:46:54 PM »
I was wondering if it was ok to swap a mirror from a 900mm reflector to a 910mm? I got a nice 4.5" mirror from a Tasco 11TR 900mm scope and swapped it into a Meade 114EQ DH4 910mm scope and was wondering if it will work, thanks for the help!
