Hi folks,
It's been a while since I posted, but I've been busy. Last anyone heard from me, I was collecting info and opinions about which scope to get.
After much deliberation, much research, and lots of nail biting, I finally ordered and now have received the Meade LXD75 8-inch SCT ACF.
Here I am with my new scope...
Again thanks to everyone who helped me do my research.
The first light report can be found on my Astro blog:
nightskylog.blogspot.com
Feel free to comment here, or on the blog itself. I look forward to hints, tips and tricks from all the experienced people on CN!

Alright Krish!!! If I'm not mistaken, the optics you have is the same as mine. As such is the case, I will guarantee that you'll enjoy your telescope for many years to come! Tell us all...what type of eyepieces are you using? I see you state the 4000 series? How is it all working out? Congratulations on your purchase!

Hi Krish!
Great scope you have there!  Welcome to the CN family! I see that you just rekindled your interest in astronomy. I also took a hiatus from the hobby. I focused on family life and rekindled my interest later. Look forward to seeing you continuing to grow in this great pastime.

Hi Krish,
Congrats on the new scope!
It's a shame about the controller being missing, let's hope that Meade makes this right in short order.
The first thing I bought for my new scope was a RACI finder, I hope to sight it in later today.
My apologies for your bad weather. Since buying my new scope, three weeks ago, I've had zero good observing nights. The RACI arrived Tuesday......you guessed it....nothing but clouds and rain since. We may have a decent viewing window on Sunday night.
Enjoy the new light bucket.
Regards,
Marshall

Thanks everyone!
@RonBurgundy: The scope come with a 26mm Series 4000 Super Plossl eyepiece. As you've already noted I have the Series 4000 whole kit coming soon. I've only used the 26mm as of now, and can't wait to try out the others in the kit.
@Mel: Yes, the balancing of duties, life, and the cloudy nights (real as well as this forum) is difficult. But one thing I've heard that really hits home for me, is, "Astronomy is a patient hobby; don't worry, the universe will still be there." PS. Your partner in crime, Gary, sent me a personal email about the Vega Sky Center!
@Marshall: Yes, it's a shame about the clouds. I really thought you guys on CN were all joking about it. But wow, what a curse it is. It's still cloudy outside and has been now for 5 straight nights, even though we got some sun in the day times. I can't wait to get some more money together to buy the RACI. I just have to make sure what I get can be mounted on the OTA.

Krish,
Congratulations on the new scope. I have an LXD-75 GEM with the AR-5 and have added a W.O. Megrez 90 & C8 on a dual saddle mount which work wonderfully together on the GEM.
From my experience, the LXD-75 mount was only assembled at the factory. There was absolutely no calibration, alignment or fine tuning done in any way. That's all up to you and the manual does NOT address most of what needs to be done. I strongly suggest you visit & join the Warp & LXD-55 & LXD-75 user groups on Yahoo and Weasner.com's LXD pages. There's a wealth of information there on how to: modify the polar alignment scope mount and then align it properly to the GEM; use the Kohab Clock for easy polar alignment; calibrate the mount for accurate Polar Home position (ignore the cast in arrows, and use your own); adjusting worm gears to eliminate backlash & play and make the movement much smoother and easier on the motors.
I would also recommend going to Scopestuff and buying some of the replacement screw & bolt hardware. Most of those components on the stock mount suck and will cause problems so do it now (this is not very expensive at all).
If you do these things, you'll get much more enjoyment out of your new rig. These are all things that can be done while the skies are cloudy and it will pay off on those good nights. Trust me, I tried using the stock mount from the factory and it was very frustrating. Bad & inconsistent goto's; motor troubles; poor polar alignment, etc.
Good luck & clear skies.
Brian

Hi Krish and welcome to CN! I am a fan of the LXD-75 system, and for that matter the Celestron CG-5, and think you will have a fine mount once you have the controller and learn it's capabilities. I agree with Brian that you get over to the Yahoo users group and use their collective knowledge if you need to. I am getting ready to do a self hypertune of my mount which entails cleaning out the old grease and replacing with synthetic, sanding and polishing the internal parts, replacing the encoder wheels and upgrading to teflon bearings. Why do this? Just to make the mount operate better. However, I've found that if you do a good polar alignment, and center the alignment stars using both a low and then higher power ep, the gotos work extremely well and place objects near center of the fov of my Antares 6" achro with a 13mm ep every time.
I look forward to your on going growth with this scope and the subsequent reports you'll offer. Once again, welcome to the Cloudy Nights family.

another guy here saying good show on the optics, my tube is shown on my avatar.
Get a 2" diagonal and 56mm 4000 super plossl ASAP if you want to go after large diffuse neb targets such as the veil, and even orion. The 5.6mm exit pupil and 1.4deg true field works really well with an OIII filter, and Celestron's 2" OIII (by baader) is only $89. OPT has best deal on house brand 2" 99% dielectric diagonals that thread right to the SCT rear cell for $99. I think the 56mm just dropped from $89 to $69 as well. For unfiltered views, you may like the higher power and wider apparent field (similar true field) of a 30-40mm range ultrawide/superwide. The best cheap 30mm 80deg EP is the 1rpd, and I am fond of the william optics 40mm SWAN for $119 (72deg). Meade 4000 QX 36mm 70deg is $99, but has a little less true field than the WO 40mm. Being an F10 scope with reduced coma, these budget 2" max field eyepieces work well. I would not make these recomendations for a faster, less well corrected scope. If you want to keep it all on the Meade tip, the 36 and 56 make a good pair... and thats all you would need for 2"er's. The 2" diag comes with a 1.25" adapter, so you would use all of the higher power eps with the 2" diag as well, and keep the old visual back and 1.25" diag in the scope box in case you sell it in the future. The 2" mirror's 99% coatings and 1/10th wave surface will also improve the views in 1.25" eps. The 36 and 56 would certainly put your 40mm, and likely also your 32mm 1.25" plossls out of a job though.
When faced with the resistance line of "I am not at a high enough skill level to get 2" eyepieces yet", the correct retort is that 2" eyepieces make it EASIER, not more difficult. I am sure many on here will agree, but I warn you to ignore the ones who will say your 1.5" scope baffle will vignette 2" eyepieces, as it is only true on PAPER to someone thinking you need 100% edge illumination for visual use. Even a C6 with 1" baffle lights up a 2" maxfield EP just fine =) (I used to do it when I had an orion 127mm Mak as well). The nay sayers are not enjoying the brighter, wider field views that a 56mm eyepiece can deliver.

Hey guys, thanks for the collective slap on the back and to Brian for the insights to hypertuning and Keith for the suggestions on the eyepieces.
I kinda wanted a 2" diagonal, and 2" eyepieces, and other extra eyepieces, but the funds right now are a bit tight. I'll have to be very careful with my money for a while, but when I get back on my feet, I'm definitely going to look into these things. Hopefully, that won't be too long, as I'm thinking the first thing I need is that RACI finder, and then I can cruise for a bit, till the next must have.

Instead of the RACI, which will cost at least $100, I recomend a telrad or rigel quikfinder, these only cost $40 and are a good companion to your visual finder. Once you have the goto working, you will find the telrad is the fastest finder for simply nailing the alignment stars, and once the goto is alligned you wont need to look through the finder anyway. For many DOB users without goto, the 1-2 punch is a telrad and RACI finder, using the telrad to get in the zone, and the RACI to spiral search for the fuzzy spot. A RACI on its own is the most annoying thing to use, because when you are looking through the finder, your head is not looking at the sky, so getting your bearings straight is even HARDER than it is with a straight finder.
I found that once I got my 10"dob (former main DSO scope), I would JUST use the telrad and then spiral with my widest field 2" EP, and not even bother mounting the finderscope. With my 8" "R" (pre-lawsuit designation of ACF) OTA, I put a basic red dot finder I had laying around on it because telrad bases were out of stock at the time, and wound up never upgrading. When I got my 11" OTA, I had the telrad base I purchased for the 8" (but never got around to installing it), I put that on the 11" and I have not remounted the 50mm finder since then.
$60+ saved on that investment (more if you were to get a new finder bracket) will almost cover the 56mm, but you would still need the diagonal. 56mm makes sense as your first 2" ep for many reasons, it is the least expensive, it will not duplicate any of the magnifications you have in your 4000 set (and it completes the whole set of 4000 super plossls), and it will have the same 52 deg field that most of the 4000 plossls have (except 40mm which is 44deg, same area of sky as 32mm at 52deg). This will not only give you an exit pupil worthy of narrowband filters, or unfiltered views in dark skies, but it will also POSTPONE the tempation to upgrade to superwides and ultrawides. The moment you upgrade that 32mm or 40mm range EP to a 2" with wider field, thats when it all starts to go downhill, and you start getting more and more widefields and your plossls end up for sale.

Good report.
I am also a fan of the LXD75 mount, even with all it's little issues it seems to be a pretty decent little unit. It's like anything else, if you look after it, it will look after you.
I no longer carry mine with the counterweights on, I just think it's better on it not to strain it.

Congrats. You will have many years of enjoyment with that scope. Another item you might look at getting is a focal reducer. That will take your scope from f10 to 6.3. I have one for mine and I don’t take it off very much. I hope the weather lets you use the new scope soon.

John, you did it!
The "bad weather go away" anti-curse did it! Sunday we got clear skies for a number of hours here in the NY area, and combined with the clocks setting back an hour, evening arrived earlier, and I got in a few hours of seeing, though under the light of the full moon.
Keith, I'll have to look at a Telrad, I'm still uninitiated as to how it works and why it's useful, but that's my research to do.
Thanks everyone!

Krish,
Get the Telrad!!! It's about as easy as it gets. I agree with Kieth, you won't even need the RACI or even the straight one that came with your scope; especially when you get your GOTO working well.
If however, you do want a RACI, then I'd say get a big one (70mm~80mm) and use as a piggyback scope. IMHO, 50mm in suburban skies doesn't see squat. You need that extra aperture to see anything, and having 80mm actually CAN see DSO's, and open clusters look fantastic. In fact, I would argue that you should spend your $$ on a decent 80mm piggyback scope instead of long FL EP's for your CAT. You can then get double duty out of your medium FL EP's by using them in the 80mm for low power, wide angle views.
Regarding EP's, barlows and reducers: don't buy anything new. There's great deals to be had in the used market on CN or Astromart. You only need about (3) good EP's and a 2x barlow to see most anything. And, if you get the F/6.3 focal reducer as Bruce recommends (I totally concur) you essentially would have three mags per EP, not including what other mag you would get with an added piggyback scope.
I know this is a lot of info to digest, but that's what this forum is all about.
Good luck, and clear skies.
Brian
