Phenomenal pictures from a phenomenal scope, GREAT work, Mr Jones!!

 

My 6" LX80 continues to amaze me with its optics. It is so portable that my Dob sits unused. I had my 100mm refractor out last night, side by side with the 6",  scanning star fields. M31 was a nice sight in both scopes. Great fun but but the 100mm lacks the punch of the 6".

Received mine late last week and was able to get it out last night for first light. It's a well built instrument, but several things are going to make me send it back:

 

1) There appears to be a large amount of internal reflection. Viewing a moderately to very bright star creates a dim off-axis circular flare that covers about 1/3 the FOV. This is independent of eyepiece and diagonal used.

2) The focuser is EXTREMELY stiff and hard to turn. This is exacerbated by the relatively smooth bare aluminum knob.

3) There are what appear to be several cotton glove marks around the rim of the primary mirror, I assume from the factory during the assembly of the OTA.

 

Has anyone else who's purchased one of these experienced the internal reflection issue? I like this little scope, but I have no desire whatsoever to take it apart and flock/blacken the offending parts. Wish things were different. I'm very disappointed because optically it seems to be very nice indeed.

Not with mine. The optics are pristine. Collimation was spot-on. The focuser is firm and smooth in both directions without any detectable mirror shift. I've looked at (and imaged) very bright and very dim objects and I haven't noticed any odd reflections. The images are sharp and clear with excellent contrast. The only thing that caught my eye was some discoloration of the crinkle finish near the end rings, but this cleaned up nicely with a damp cloth.

 

Just for yucks, after imaging the Hunter's Moon with my scope I slewed over to NGC 457 to take a series of unguided images. The field includes a bright star that can give me some trouble, but these turned out well...

Thanks for the report. I suppose that I could have received a lemon. At any rate it's going back, and I'll remain optimistic and order another.

Yeah, that's the deal with close-outs, sometimes you get the rough ones. I've bought several telescopes from Meade's close-outs and so far I've been pretty lucky.

 

I finally got around to downloading the pictures out of my camera.

 

My baby...

Good decision.  Sounds like something is bent.  Don't tolerate it, we have to live with these things for years and years.  Would be interesting to hear how the retailer handles this.

Thank you Neil. It's been a lovely, albeit rainy day.  :flowerred:

My replacement came yesterday and I was able to get out with it for a short time last night. The good news is that the internal reflection and stiff focuser problems I had with my first OTA are not present here. The focuser is as smooth as butter and there's no noticeable image shift. After tweaking the collimation, which was slightly off, the views were very nice indeed even from my red zone location. It's not all unicorns and ice cream though. The new OTA has a line of small pits about 2 inches long on the outside circumference of the mirror cell. They appear to be a casting defect. It's cosmetic only, but it's there and I'm disappointed since it's a brand-new unit that never should have left the factory with this issue. Meade's QC, at least from my first-hand experience here, appears to be lacking. Now I have to decide whether or not I'm going to keep it, send it back for swap #2, or just return it.

 Suspect that these are end of production units and that very well may not have met final production standards. Mine was discolored where the crinkle finish met the end rings, something that I would not have been happy with if I had paid full price for this telescope. However, having bought quite few production leftovers at great prices I'm okay with a few cosmetic defects. As long as the scope is optically and mechanically sound, I'm good to go.

I have a 6" OTA which was from a broken LS mount in the UK. The dealer added a dovetail rail and synta type finder shoe which i added a 8x40 finder.  I have yet to decide how best to mount it though, and It's only for visual use.  Ideas and suggestions most welcome !

I used to mount my 6" LX80 on a Unistar Light mount on a heavy duty photo tripod. A finger tap at the eyepiece took 5 seconds to dissipate (not too good). But it was very portable.

 

Recently, I upgraded to an Orion VersaGo II mount on sale. It's light, cheap and solid. A finger tap dissipates in 1 second, a big improvement. I don't use the tray or the handle. The tray locks the legs in the open position which makes it more difficult to transport. The handle is supposed to make slewing easier.  The handle is rather large, a nuisance when carrying and unnecessary. In its current configuration the 6" LX80 on a VersaGo II is fairly portable.

I've got my baby LX80 set up on my Celestron NexStar SE mount, so I thought I'd post a few pics...

How did your M6 perform optically?  looks nice.

I was only able to get it out for a couple of hours two nights ago Bill, so I didn't have time to do a super-critical evaluation of the optics. However, during the short time I used it was impressed. I plan on spending a few hours with it tonight and, hopefully, will be able to compare it to my C6 SE.

Okay, that sounds good.  Would be interested in how the M6/C6 stack up against one another when viewing the same objects.

Looks like I won't have a chance to do a side-by-side until this weekend Bill. Stay tuned.
