I had a friend come up from Scottsdale, AZ to view with me.  We tried to practice social distancing smile.gif.  He brought his Tec 140 and night vision device and I supplied the Tec 160, 180 and 200.  Lots of fun!

I like how in this picture the 140 looks like it is the largest scope.

That is certainly a beautiful collection of fine optics  waytogo.gif

 

The only TEC I have owned is the TEC MC200F15.5, it showed to me the attention to detail in TEC scopes.

We don't see many TEC refractors down here in Oz, if we did I fear my bank account would take a hit !!!

This was a surprise to me while searching through some old posts on TEC Maks I came across a post by Yuri where he wrote that the popular 200F15.5 Mak is in fact 200F15.7.

Jumpin catfish!

This is like a wet t-shirt contest for refractors. I bet the 140 didn’t take a back seat to any of them. Thanks for posting this Kent, I look forward to your impressions from the refractor-fest.

Hi Mark,

 

Yep, all great including the smaller 140.  Just different views.  We could see more galaxies in the FOV from the Virgo cluster in the 140 (using the NVD) but in the 200 dark lanes were more easily seen in other galaxies even without the NVD. 

 

We compared some double stars and it was as expected.  It looked like more separation in the larger scopes and stars were brighter.

 

It got late quickly and it seemed we didn't have enough time.  But I am sure we will do it again.  My friend wants to come back for Mars.

If I had to pare my gear down to one scope it would be a 140 (I'm currently in between 140's).  Very well built, light weight, excellent optics and versatile.

I forgot to mention, behind the TEC's, I had the 16.5" dob out as well as my TV 140 ready to go.  But again, time was short so we didn't use any one scope a whole lot and I never did set up the TV 140 which we were going to compare with the TEC 140.

Kent you should have lined up all the OTA’s before mounting them. That would have been a classic photo.

 

Now tell us, if you could only keep one, which would it be? Cruel question I know.

Hi Allan,

 

I had my camera all ready at my back door so I was planning on a nice picture, but I set up quickly and my friend set up quickly and then I said hey we need a picture.  Then we talked some more so it was getting late and we wanted to view.  I took picture #2 above 1st and then thought about pointing the scopes in the same direction.  You are right though.  It should have been a picture like below.  And it may have been nice to have the dew shields all open, more impressive, but I like cooling my scopes with the dew shield closed as long as it is not too windy.

 

If I could keep one, it would be the 200 of course.  I love all my scopes for various reasons but I am using this one the most.  The day before TECfest 2020 my friend was at a dark site, SQM 22.1 is what he measured, an hour away from me and said he could see Omega Centauri from there.  I have never seen it so I would like to get there some day.  Thought about it tonight actually.  But I will be bringing the 180.  The 200 would be a major job.  So all my scopes have uses and as I was saying different views but I use the 200 the most right now and would not want to be without it now that I have had a taste of an ~8" APO.  I better not look through Yuri's 250 or 300!

I knew you’d choose the TEC200 Kent, I was just playing. You’re lucky to have some options for a big permanent setup and something a bit smaller for travel. You need to get your TEC180 to Omega Centauri.

Allan, I took your advice.  I took the 180 and went to view Omega Centauri.  It was amazing.  One of my favorite views.  It was very low, of course, and I had to plan carefully where to set up with trees and small hills in the area.  I was told it would show up at 10:30 but I checked early on to try to predict where it would show and at about 8:45 it came from behind a hill.  I couldn't believe it.  And the seeing was quite good considering how low it was.  I went from a 35mm, 25mm 20mm 16mm, 10mm 6mm and 4mm eyepieces to get all sorts of views always seeing granulation.  Used my Clave and ZAO I.  Tons of granulation.  I also used some wide FOV eyepieces but there was less granulation then.  I stared at it for about an hour and then had to move the scope a little after it went behind some trees.  Now the seeing wasn't so good and it just looked like a cloud, still impressive but I had already seen the best it had to offer.  I went to some other objects, M13 and it was no longer so impressive even in these dark skies.  Still nice though, higher in the sky so at least I could see individual stars and the propeller.

 

Thanks for encouraging me to go.  This was the last night because the moon will now be too bright and then next new moon it will be too low.  Maybe I will go again next year.

I have been fortunate to see Omega Centauri at the Texas Star Party through my friend's TEC 180 with TV eyepieces.  It was stunning.  I had seen it before in smaller refractors and larger DOBs, but the 180 framed it the best IMO.  A great scope on a beautiful object;  an image burned into my memory.

It was probably the 1st time I got to use a case I built for my 180.  Nice and light compared with the original case.

Maybe build isn't the right word.  I bought a golf case and cut and glued the foam inside.  A perfect fit and it is really light but protective with a handle on top and on the sides.  There are wheels on one end too.

 

Here is a comparison with the original case.

I love it!

Thanks.  It makes traveling with the scope relatively simple.  I spent the most time just making sure I had everything.  Loading up was quite easy to do by myself.  I doubt I will ever take the 200 anywhere.  That would be very time consuming.  A star party and a camper, maybe then but I don't see that in my near future.
