The clouds unexpectedly opening up for awhile last night. I was also wanting to test a new Paracorr 2 as well so I rolled out the Orion xx16g. I even didn't bother with alignment and just free handed it.

 

The "Meade" 5.5mm allowed for a very nice view of Jupiter. The two main cloud belts were very clear along with the Great Red Spot. I could also see the shadow of one of the moons on Jupiter. Seeing wasn't super good. The edges of Saturn had that "frying egg" look at the edges, but I could definitely see the ring with wavering hints of the Cassini division.

Thanks to this thread, I was able to reaquire a Meade 5.5mm, 82 degree eyepiece.  I sold mine a couple of years ago and was sorry afterwards.  So, I ordered one from Aliexpress on Oct. 21st and receieved it yesterday, Nov. 4th.  I just took it out in the daylight and saw no problems with it. I found views off in the distance to be great....my neighbor's truck was about 100 yards away and I could see the front "FORD" label clearly.  It will be a while before the clouds clear for night viewing.

 

My 5.5mm has a cap on top with the "star" logo and says 5.5mm on the side but there is no mention of Meade.  Who cares....I got this eyepiece for $86.00, including shipping.  That's a deal in my book and I'm happy to have it again.

 

Clear Skies,

Mondo

Would like to see more reports of these eyepieces on astronomical objects in decent conditions. Jupiter in good seeing for example

We expect good seeing on Monday and if so, I'll be out there with the Meade and report back.

For most of my scopes, 5.5mm is near where I stop needing glasses for astigmatism. At less than $90 shipped, what the hey. Looking forward to using it at 100x in my small fracs.

Still waiting on my 5.5, ordered on 10/21. Still somewhere between China and US. USPS has shipping #, just no other info. Expected delivery was 11/4. Hoping to see some reviews from those who have received theirs.

Would you mind providing a pic?  Think a winged eyeguard could be added?meade 5000 uwa 2.jpg

I never liked winged eyeguards, which is why I haven't equipped them with any. I'm sure though that many readily available eyeguards can be used to do the trick!

The seeing wasn't really great tonight but it was good enough for me to compare my Meade 5.5mm, 82 degree to others with similar focal lengths, such as my APM 5mm, 100 degree and 6mm Televue Delos.  The views from my Meade compared favorably to the others, proving to me that the eyepiece is as good as the first one I had and sold.

Sold mine for a 6.5mm Baader Morpheus. A bit less mag, but definitely better when I wear my glasses, and the Morpheus is almost an 80 degree eyepiece. 79° actually.

My guess is he was using too high a mag at 461x with the sct at least along with sky stability, miss collimation and a host of other factors could all be the reasons for the disappointing view.

 

Jupiter taking up 85% of the fov seems illogical...as Spock would say

I've seen people on here talk about using 1,000x to 1,500x magnification on planets, but now 461x is too much?

For an 8" SCT, yeah, typically is too much.

 

This past year, save maybe some of last Jan/Feb, was horrible for viewing conditions. I haven't gone anywhere near 50x per inch in any of my scopes this year, mostly hovering around 25x per inch max. Not coincidentally, we had virtually no fire bans for any meaningful amount of time...

Ahh yes. Conditions mean everything. You are right there.

Just a note: though labeled 5mm, the APM XWA 5 is really somewhere around 4.7-4.8mm focal length.

Thanks Don....I pretty much knew that when I bought it and my spreadsheet, where I list my eyepieces with their AFOV, Mag., TFOV, Exit Pupil, etc. lists the magnification using the 4.8 focal length in the calculation.  By the way, I'm really happy with the APM 4.8/100 eyepiece you sold me.

 

Clear Skies,

Finally received my UWA 5.5 today. Ordered on 10/21 it was $78.95, $92 shipped. Plain foam lined black box., no mention of Meade anywhere. Twist-up eyecup works fine, had to clean off a little grease. Clouds tonight, forecast of mid 20's for the next week., might be awhile before I get to test this out. But, I'm happy, been searching for one on the used market for 6 months.

Got mine today at lunch when I went home. Waterproof package with plain black box. Nestled into gray foam in box. Did not try too hard to roll up the often greasy and hard to deploy eye guard, and prob won't use it. Just like others have reported so far. Meade on ep top cap, clear end cap, barrel marked china, optics look clean and nothing that I noticed out of the ordinary. I will post again here after using it in the f/4 4.5 inch and the f/4.5 16 inch. Clear skies and happy Turkey Day! Xmas came early , as it was supposed to be here 12-6.

Got the 4.5 inch f/4 out couple nights ago and only took a look at jupiter and the beehive cluster before clouds moved in. I like the view thru this ep so far. stars seemed clean and nice across the field.

My AliMeade 5.5mm arrived last week. I used it in my spotting scope (80mm, f5.4). Great views of Jupiter - 2 bands clearly visible. Sharper and better contrast at 5.5mm than my SV191 7.2-21.6 zoom at 7.2mm. For me, it's a keeper.

The Meade 5.5mm UWA eyepiece is inexpensive, yet it has very good optical performance: sharp, no kidney-bean effect, rather long eye relief (for its focal length), it is really a keeper. I see people using it (and the 8.8mm) along with premium eyepieces such as the TV Delos line.

 

I am impressed by how much improvement the Chinese manufactures has made since early 2000s. 

 

The Chinese will find the path to light.
