Lets talk about the Meade SN-6 schmidt newt..

I've also found that the SCT overall makes a better general purpose scope, but for deepsky imaging I much prefer my SN. For visual-only I prefer either my biggo achro or my MCT, but for a little bit of everything I like my SCT; it's a lot of scope in a small package. It's nice to have options.

EDIT... Maybe I was missing something on the collimation of the SN. Check out this LINK. I am not convinced it will require that much work
Wow, I hope mine comes in somewhat close to collimation. I don't want to tear the scope down right off the bat! But it's nice to know there's some help out there, if needed.

If I get one of the SNs, I'll be putting it on an Alt-Az mount, so EP position shouldn't be an issue. I'd guess the SN is significantly heavier than the SCT? I'm hoping to mount it on my AT-Voyager, and the wider FoV of the SN is appealing to me.
Ideally I'd like a 6" f/5 Apo which weighs less than 15-lbs, 10-12-lbs would be OK.
All the 6" f/5(ish) Apo refractors available right now seems to be exclusively geared toward astrophotography, and are consequently very heavy and bulky, obviously for reasons of stability/rigidity. I know the TV NP127 is quite light, but to me, 5" isn't enough of a jump from my 4" refractors.
I figured the 6" SN would be Apo-like enough for me, but may also be too heavy.
Thanks for the advice,

And yes, the SN6 will be heavier than an SC6; the tube is longer and you have the mounting rings that you usually don't have with an SC.

I ordered mine at about the same time and I just now got my shipping notice. It should be here Friday! Yay! I've been tuning my 'spare' LXD75 to have it ready for it. Gonna be fun.
Yep, my timing is always good with this stuff. I sent them an email asking where the heck my scope is, within half an hour get a ship notice and tracking info saying it shipped yesterday. My better half is out of town this week, so it NEEDS to get here this week!

Good luck with that! I'm kinda in the same boat, except the wife is not out of town. At this point though, she just shakes her head when there's a box at the door.
I haven't got a shipping notice yet either. Submitted my order on Sunday...thought I should have the shipping notice by now...

Well, that explains all of the rain in the forecast...
Not had a clear night all month. Was wondering if there is a coincidence. I'm generally not superstitious.

LXD55 mount turned out to be very nice as well - it has lighter tripod which is not bad for visual, it has very nice clutch action and smooth motion so it can be used for manual targeting.
I am afraid this will become my favorite setup.
Next week I am heading to NC to spend some time on beach. The place is in green zone, so it will be really interesting to see how it performs under darker skies.

1) Anyone know which focuser is the easiest to install?
2) recommended accessories are:
Laser or chesire collimation tool
3) Buy for a refractor (not an SCT?); the collimation tools seem to come in those flavors...
I am not going to run out & buy all of those at once... which is the most important?
Stellavue Nighthawk 80mm refractor
A bunch of ES eps

As for replacement focusers; I've seen SN's with Feathertouch and MoonLite focusers. I think MoonLite is the only one I've seen that had an isntallation kit specifically for the SN6. The Feathertouch looks like it's a lot lower profile. The SN6 is designed with a lot of back-focus and has a built-in removable extension tube to accommodate a variety of cameras (leave it on for CCDs, take it off for a DSLR). Before replacing the focuser make sure you get one that will work with your camera.

I've only had the moonlight and it was easy to install. You do have to remove corrector but it can only go back one way unless you rotate the secondary mirror.
As for accessories if you aren't imaging and not using heavy 2" eps the stock focuser works. IMO the most important accessory is a laser collimator and a dew shield everything else can wait. If imaging the focuser is most important IMO.

Were you imaging with MPCC?
Another question to folks: anyone tried putting teflon strips into focuser between the tube and base? It helped a lot with other focusers of similar quality.

The stock focuser works fine; turn the knob, tube moves in and out, image comes to focus. I had to tighten the scerws holding the rack to the draw tube and snug the locking bolt a bit to firm it up. The only mod I've made to this scope is that I added an electric focus drive that was originally designed for the DS-2130.
Perhaps it 'works fine' because you're using it with an electric focuser? If the focuser is anything like the stock focusers on the classis Chinese Dobs, I may be looking to upgrade to the moonlite. I already have a Moonlite CR, so I'd just have to get the conversion kit.
