Geeze, talk about a tough crowd!

Clearly none of you guys were early adopters of Losmandy's Gemini 2... I left that camp after a year, about a month too soon I think, PEC got sorted soon after I heard

My point, have a little faith in SB and be patient...

I put the RC on as the mach 1 for testing in my home observatory, it makes optical/system testing easier. After testing, It was transferred to the remote obs, and mounted on the PME. The mach 1 was not stressed with that weight.

The Mach 1 has the ap130 and FSQ combo back on now.

Greg: The PME in my obs has a levelling bubble, and I'm pretty sure it is OEM.

Marcus, for these sorts of Qs you really need to post directly to the SB Forum. Be sure to include as much data and screen shots as possible. Like most specialist astro gear these days (AP, Tak, Planewave, Losmandy), the dedicated support forum should be your first port of call. Actually, good of SB to even provide their own forum, the other big players bum off the YahooGroups system which I'm not a fan of.

Briefly, I did a series of 5min exposures a few weeks back with the MX, unguided, similar FL to your FSQ with Sky90 - Protrack on - and the result was ok in my opinion, though not worthy of posting to this site's DeepSky section. Will attach soon. Good luck with it. Logan.

Reason i ask is that mine does not do more than 1 min with or without PEC and Protrack ( with a 400+ T-point model ), so all i do is guide Was looking forward to imaging without guiding. Thnis is with an FSQ106 attatched by rings directly to the mount with even a small DSI 2 instead of the usual st8300 i use.

Unguided with a small T-Point model of about 50pts from memory. I've head that Protrack responds far better with more points...

Generally speaking my understanding is pec smooths out over time specially when the worm is new. So sooner or later one have to redo it. Our ap initially had 3+ arc/sec pec which is <3 after a year of moderate use. This is not to say ore loaded pec is not useful.

Ah yes. I noticed that with the Tak NJP I had. It got better with age, smoother, less PE. It had good PE to start with but excellent after a few years.

I am not sure about the history of PMEs but the levelling bubble is an accessory sold by Rob Miller. Mine did not have one.

It's also an accessory sold by Software Bisque. I have two of them on my PME. One on each side. They each read a little differently!

Here is a image of the Horse Head Nebula taken on my MX, with it's new worm block.

This is a 10 minute unguided exposure, with Pro Track on. The PEC has not been programmed this is why there is a small amount of movement in RA.

The image scale is .6 arc seconds per pixel.

Camera SBIG STi mono.

OTA Planewave CDK12.5

Mac OS

I measured the PE of the new worm and it is around 3 arc seconds peak to peak. I will need some clear stable sky to correct it effectively.

I am thrilled with this result.

The MX is an awesome mount.

Cheers

Hi Marcus, how are you?

I am very happy with this result. Blown away actually, a focal length of 2541mm and no PEC training I can't ask for much better than that.

I only did 140 points to create the T Point model.

I used both sides of the meridian. I selected targets all the way around my visual horizon then worked my way up to the zenith. I used Image Link to add the pointing samples.

Once I have finished testing I will do an automated run with 500 points or more. This will give Pro Track more to work with. Having such a low PE I will need a very stable atmosphere to train PEC other wise I will be recording the seeing and it won't improve.

You should be able to achieve the same result. Feel free to send me a PM with any questions you have, or if you are having trouble post on the SB forum, there are some very knowledgeable members and SB staff willing to help.


Cheers

I thought I would add an update.

The worm that was being sent to me did not arrive.
I did not receive any direct communication from SB despite my details not having changed when I bought the mount (they received the money no worries).
I have to be prompted that someone left a message on their website blogs. They are asking for confirmation of my delivery address so UPS can deliver. They never sent me a tracking number which is the first thing anyone does when sending you something.

I sent an email plus a fax detailing all my addresses and email addresses etc.

None of this is acknowledged by anyone there.

I receive a question did Colleen from SB front desk (whatever that means) email me?

No I did not. Front desk apparently refers to their physical reception as I thought maybe its some obsecure reference to a spot in their complex website.

I called them twice now during business hours and noone answers. It says leave a message in general mailbox and then it says the mailbox is not open and to leave a message. I left a message and that is where its at.

Do you see a pattern here? Is it clearer why there are issues with the mount now?

Greg.

That sounds very bad Hopefully it's due to the fact that they are working fulltime on getting mounts out or ....
But still after all that and no response makes u wonder.

I agree with Greg, SB responses to their clients are suboptimal, many questions directly related to their products at their website or emails (my experience) are unanswered or answered halfheartedly, more often by some nice enough users. I also feel their southern hemisphere buyers are neglected in their software development,testing and post sell services.

Exactly the same re their dome software. Totally ignored until I went online in a public forum and detailed their total lack of service and after sales care. Then they stepped up to the plate but only half heatedly. Ask Houghy about Automadome - he just loves it (NOT).

Greg, do us all a favour, go ahead and list your MX mount on the classifieds and be done with it.

My replacement worm block arrived last week, express shipping from the US. Superb service. Period.
