O.K................sorry, no first light yet
Got stuck with unannounced visitors last night

Anyhow, here is a start to where I am at:

Losmandy dovetail mounted to tube.
This was fairly straight forward : 4 bolts had to be removed underneath the tube to make way for the bolts supplied by Losmandy.
There were also two small screws at each end of the tube (between the bolts) that needed removal to make room for the curved cradles at each end of the dovetail.
If these are not removed,it's impossible to fit the dovetail!

On general inspection of the OTA, it appears to be very well made - solid construction, nicely finished off and smooth/professional feel to focus and mirror lock controls.

Taking off the front cover (metal)and looking in to the tube, seeing that big mirror at the end sends goosebumps down your spine !!

I have fitted the large D style head back on to the EQ6 which is now ready to accept the Meade OTA.

The extension bar may be needed to obtain balance. Not sure on this as I may even need an extra counterweight?

Hopefully tonight may be first light if weather holds and I don't discover that additional weights are required over and above the extension bar.

I will be very interested in your opinion on the EQ6 with this scope - Im either going to get the NEQ6 or Celestron CGEM.

If the NEQ6 is not up to the task, then I might have to save up for the G11

Hi Tim,me too.

Remember though that I will be using the scope for visual and some planetary/video imaging so I won't be overloading the mount as some have to later discover problems ocurring.

The NEQ6 PRO has car bearings as mentioned once on a forum, so it can't be that whimpy?

The Celestron mounts are very good too but their OTA's are also lighter compared to the Meades...............make you think?

Just before sunset last night, the skies were mainly clear with a few clouds here and there.
So, ...........I set up the scope on the mount. WOW!..........what a sight to beholdthe scope and mount look amazing!

Then it got dark..........I walked outside and there was NO SKY..................just clouds!!!!!!!!!!!............ ..typical!!!!!!

I have my 12" stuck in a cupboard. At the moment all I can do is open the door, give the focus knob a twiddle, and close the door...

First light!

Last night was the first opportunity to have a quick peek at the skies.
Transparency was not the best as there was high cloud haze present throughout the day with numerous clouds about.

Thankfully the clouds began to dissipate as the sun went down, but as I said, it was noticeable that clarity of the heavens was not going to be first rate............5/10
Seeing was about 6/10 and there was only the slightest hint of a breeze now and then.

Setting up the scope was surprisingly easy. I found that picking up the EQ6 tripod, with legs folded together, with the head already attached(less counterweights), and slung over my right shoulder was a quick and effective method of getting the mount outside.
Next was the weights themselves and another chunk of steel Gaffa taped to the weights to enable balance.

For last nights quick view, the mount's electronics were not connected.

Another surprise was how easy it was to grab hold of the handle on the OTA, hold the other end and simply lift it up on to the dovetail head.When positioned and still holding the handle(!!),the screws were tightened and the scope was mounted..............love that giant Losmandy dovetail bar!
I expected this to be a two man job, but it wasn't.

I used a Bintel 2 inch quartz SCT star diagonal and an ordinary 2 inch, 26mm 70 degree Chinese eyepeice. This eyepeice is a mystery. It was sold to me as a Skywatcher brand, but there is nothing on the e.p. to indicate this.It looks exactly like a PROSTAR I saw advertised in a magazine recently, so who knows?

Down to business...................ORION NEBULA..........wow!
Keeing in mind that the scope had barely an hour to cool down, seeing and transparency were lousy, yet what I saw through that ''questionable'' e.p. was nothing short of staggering!
The nebula was crystal clear and just hung there in space with numerous pin point stars surrounding it. There was a hint of pale green and some pink around the edges. The trapezium was easily resolved and looked better than ever.

PANNING AROUND : this was also an eye opener. A large aperture scope with coma free optics is something that I'm not used to. I found myself constantly stopping, looking at open clusters in awe. The views were spectacular showing colours in the stars themselves effortlessly.

CENTAURUS GLOBULAR CLUSTER : say no more!..........amazing... .....but it looks good in most medium - large scopes doesn't it?

THE EQ6/MEADE 12 INCH LX200 ACF COMBO: I know that many of you out there would be waiting on my opinion of this, so here it is:

At no time during my 30 minute, short lived (those clouds!!) viewing session did I feel that the mount was inadequate to hold a 12 inch SCT.
Being fair, the scope did not have any photographic equipment hanging off it or any large guide scopes sitting on top of it.
I found that vibrations caused by adjusting the focus knob were minimal and settled very quickly...........no dramas here. The slight breeze experienced now again did not cause any visible image vibrations as far as I could see.

Focussing itself wasn't as coarse as I had anticipated............nothing like a standard rack and pinion job that's for sure. I found it easy to bring an object into focus with minimal if any backlash.
Image shift?................ummmmmmmm?... ......can't comment on this as I did not notice anything unusual at that power in such a short time.

Well, that's about as much as I can report for the moment.
The Meade is one hell of an instrument..........you guys were right!
If it performed this well in very poor seeing, I can see that it will even be better when temperature equalised and the seeing better than that watered down pea soup last night

Until then!

Rob.

Last night being high clouded was not what we wanted to hear.
But your report makes the OTA sound very delectable - I hope the EQ6 works well for you as that's my next upgrade and I shall be watching !!
I've found my Meade OTA to be excellent (though it's only an 8" ACF) and like yours has virtually no image shift and smooth focus.

I hope tonight is better and you get to really put the baby through its paces.
Looking forward to seeing some DSO pics!

Congrats - sounds lovely -

Great 1st report
however cool down to ambient will be in the 4-6 hour range at the moment
You'll need to do the peltier cooling mod to get to 1 hour cool dowm for it to perform at optimum

Thanks for your early input guys!

Yes, last night was really only a cheap thrill and a desperate attempt for a long awaited ''fix''

Agree with adequate cool down time GrampianStars...........but I couldn't help myself.

jenchris, very interesting to hear that you have also experienced ''virtually no image shift and smooth focus''.
I thought it was just my ignoring it's presence and hoping that everything was peachy in the excitement of the moment

There will be a definate follow up on this first report on the EQ6 mount used with a 12 inch SCT.
There has been a lot of talk and disagreement on this issue and I have been researching opinions from many sources for a while now.

At the moment the OTA with Losmandy dovetail bar, diagonal mirror and heavy 2 inch eyepeice could possibly be around or just under the 18kg mark?...........I don't know for certain.
If the mount was already overloaded as some may suggest, it should be bouncing around all over the place..................but it isn't...........that I'm sure of.

My idea is to use my 12" meade for purely visual and planetary imaging - I believe the EQ6 or CGEM will be good enough for that.

I simply cant afford 4,500 for the next most affordable mount up, which would be the Losmandy G11.

Agreed Tim.
How much does the CGEM cost?

Sounds like you had some fun Rob
I remember when I first looked through my 12" Meade SCT it was fantastic, 12" is a good aperture

Enjoy!

Well Tim, in my opinion, the EQ6 will save you money........read on.........

''SECOND LIGHT''
Last night the skies were a totally different affair.........clear and steady

M42 and the Centaurus ''glob'' were in my sights as they were the primaries viewed the night before.

M42 was jaw dropping this time..........even more detail, pin point stars peeking through the nebulosity............I could go on and on

The Centaurus big Globular was enough to skip a heart beat(and I think I did)............fantastic resolution from core to the far extremes.
God I love this scope!

How did the EQ6 hold up?.....................ROCK SOLID..................surprised the hell out of me!
If you are going visual only, the EQ6 won't even break a sweat.
If you decide to do some photography, I wouldn't be surprised if this mount could accomplish quite a lot..........more than expected.

I'd say that it's ''firm'' and not too easily moveable unless you want it to....... if that makes sense?
No doubt with use, it will turn a bit easier down the track.

It has a ''quality'' feel about it. In use, there is a small amount of backlash, but it's hardly worth mentioning in my opinion.
Getting a target in focus is no problem at all.

Cheers,
Rob.
