I took a peek thru a 5" version back around 1999 and it seemed very sharp.

Any Intes Mak I have looked through has been very sharp.  They are very good scopes.  It was always interesting to talk to Mike Palermiti who ran the shop in FL where a lot of Intes scopes came through.  Mike tested every scope and provided a certificate with each scope. He had a low opinion of Meade and Celestron SCT's

That is a wonderful image Rolo.  What camera did you use to take it?

I still have a set of optics for a 9" Intes Mak. I am really beginning to wonder if I will ever put them in an OTA.


Any pics?

Mine was a once in a lifetime find... 

Wonderful image rolo

 

I know what its like selling a scope and regretting it.  Set me on a path to getting the 10 inch intes.

 

I brought the 715 off a Mike P in florida around 2001 I think sold it a few years later to purchase a c11 nexstar for a dome I was building.

 

Sold to a hoarding friend and have never been able to get it back.  However one day not long after trying yet again to buy the scope back I logged onto trademe and couldn't believe my eyes a 10 inch f10 intes micro delux with a $1 reserve in New Zealand go figure!!!!

 

I was prepared to pay 4000 NZ for it but got it for $2080 NZ got to be the bargain of the century I reakon.  Needed collimation and the chap that had it was also selling a 6 inch tak fs152 so he knew his onions.  A lot of that finer detail in that webcam image comes out in good seeing on Jupiter in the 10 just little glimpses.

 

Rolo hope you are back with the webcam soon hang in there.

Intes-Micro "160mm f5.5", one of those Markus Ludes specials. In quotes because I measured the corrector and it's 155mm, still bigger than the typical 6" (152mm). I guess 160mm may be the primary diameter. I have yet to measure the focal length accurately but I suspect it may turn out to be slightly slower than 5.5.

 

It has a quartz primary, polished clear at the back for quicker cooldown (A-P and Zambuto do this as well). Has a boundary layer fan as well that I rarely use because it equilibrates so fast. JMI dual speed focuser. Star test is perfectly symmetrical to my eyes, easily corrected to 1/10 wave or better (I have the interferometric report somewhere that says just the same).

 

Perched on an iOptron AZ Mount Pro, which can just about handle its 20+ lbs. Home made "Wilcox" ring for easy rotation, including my addition of a PTFE sheet to make rotating smooth, helped by the three tabs on the lower part of the OTA.

 

The best thing is that the entire rig cost me less than a 4" Japanese apo would.

 

There is something about white scopes on white pedestals that just appeals to me.

So I guess this is as good as any thread to ask this.

 

I have borrowed an Orion Mak-Newt from a friend who is not using it for now.

It's a White Tube Orion but on the back of the mirror cell is Alter MN55.

 

Does anyone know the specifics? Like what makes it a 55 rather than 56? And is Alter(-Micro?) a different brand?

Thanks for any info. I do not find a manual for it. Orion is usually pretty good about that.

 

Clear skies!

first digit is aperture, second digit is focal ratio I believe. 

Thus MN56 is a five inch mak newt with focal ratio of f6, which in turns moderately small secondary obstruction. 

Less illumination for wide field eyepieces but more small scale contrast for planetary.  Everything is a trade off, no naglers here with that scope, and you may see illumination fall off with delos @ 72 deg.

Though if you use high power eyepieces, even Naglers will do well. Illumination falloff is seen only at low powers. An easy way to determine it is by defocusing a star and viewing it off-axis. If the stellar disk is out of round, you have illumination falloff.

Not always ... Intes numbering was bizarre.

M500 f/10 (mak cass), MN61 was f/6 ( mak newtonian). M61 was f/12 (mak cass). M606 was f/6 (photo Cassegrain), M63 and M603 were f10 (Mak Cassegrain).

And that just for starters. Many other models with inconsistent numbering.

To that add the Santel scopes which have intes optics.

Absolutley, 

the MN61 is a 6" f/6...  My MK-67 is 6" f/12...

 

You also need to consider that: Intes, Intes Micro, Intes Micro Alter, and Intes Santel are 4 distinct and very different companies.  I'm hoping someone with better information will chime in and elaborate on this point...  fingerscrossed.gif

The history of these is described in an older thread on CN with links, no need to repeat it here. Google is your friend.

There were connections between them such as former employees of one starting another etc..

I precede Google on the net... by about 15 years, maybe more.

So I am well aware "Let me google that for you. (LMGTFU)" There is precious little I see in the results. Cloudynights or not.

 

So perhaps not being so quick to LMGTFU is as helpful as it could be.  And maybe, if your search engine fu is better than mine, post the links. I would be very grateful.

I believe that Intes-Micro and Intes-Micro Alter are the same company.  The ÔÇťAlterÔÇŁ refers to a translation of an ÔÇťastronomical telescopeÔÇŁ.

Darn! Missed out on a 6ÔÇŁ Argonaut MC by about $30. Undoubtedly somewhat more than that, depending on how high the other guy was willing to go. Would have been interesting to compare to my iOptron, but such is life.

I think it's worth pointing out that there was Intes/Intes-Micro and then there was Markus Ludes (APM) version of Intes Micro M-Ns. The latter were specially sourced optics sets, often with quartz mirrors and odd focal ratios. Came with JMI focusers and boundary layer fans and sometimes OEM dew sheilds. In addition APM also had Matthias Wirth make OTAs using Intes-Micro optical sets but ones I've seen have been MCs.

The early ones I saw had decent optics but way overbuilt and somewhat crude. They got better as time went on, mostly due to Markus demanding changes to them. Even so I have seen some with less than stellar optical quality, guess it depended on what day of the week it was built on. Also have seen some with very good to excellent optics, just let down by mechanics unless APM spec built model, and even some of these had problems (MCT's).

 

The MN's seemed much more consistent from the ones I observed through or knew about. Still on the heavy side, built like a tank.

 

I would stick to models made after 2001 unless you can use it before buying or know the seller.

They had great optics in their day, had MN86.

Now everyone has caught up and surpassed them.

Any newt with papers is better.

I'm very happy with my Alter M603. I live less than 2 miles N of Detroit so my viewing is mainly the Moon, Jupiter, and Saturn. I did get some Baader solar film in time to the last eclipse.

The only DSO so far has been M78, although I thought it was M42 at the time.foreheadslap.gif
