Hello CNers,

If you had a $5000.00 budget for a Refractor what would you buy? This would be for visual only and Night Vison Astronomy. I usually buy one high end ticket piece of Astro Gear a year and would like some Thoughts on this. I already own a couple of nice four inch Refractors  a AT102ED and a Altair Starwave Ascent 102 ED  F/1122 and I have a AT72 ED11 on the way. What would you buy?  

 

THANK YOU EVERYONE AND KEEP LOOKING UP Jethro

Probably a TMB in the 110mm-130mm range

I'd use the $5000 for a deposit for a CFF 160 f/6.5 and then use next year's installment to pay it off.  It will probably take 9-12 months for CFF to make it anyways.

I'd pad in another $500-800, and find a used Astro-Physics 130EDFS.

For visual, the bigger the better (within reason). If you have a mount that can take a 6" that's what I'd choose. The common APM 152mm ED doublet should be fairly affordable although it's not the best-corrected option. There are a lot of options at 130mm and 140mm, but finding a 6" triplet for $5K is going to be hard but probably not impossible.

This would be for visual only and Night Vision Astronomy.

With your visual background I would consider AP. If interested, I can share more details how to go about it in $5K. I look at your signature and it is busy. Why not consolidate a bit and dip in AP? Regards

I'd (and actually I did) buy a used Astro Physics, 5" EDF. Extremely good for wide and planetary views though just a F/6.

Relatively light and short, great optics, valuable across the time.

I would go back to a Sky watcher 6" ED and buy another used AP800 like i had before.  But it was the size of the mount and 7 trips to setup that was the cause of me selling it.

I like my Skywatcher 150 ED Evostar refractor very much and it’s much better than I thought and I keep it! Jupiter,Saturn and Mars look so good! If it’s too big for you then go for 120 mm Skywatcher or between 120 and 140 APO refractor!

 Skywatcher 150 triplet. And EQ6 goto mount(if current mount not sufficient). Pay half now and pay off next year.

 

Triplet better for AP.

 

For only visual , the SW 150ED doublet and mount(if needed)I'm one of many satisfied SW120ED owners.

I would look for a nice used 5-inch refractor.  Your G-11 mount can easily handle it and you have the smaller sizes covered.  I have owned a couple of C8-HD before and they still don't show the pin point stars like a decent refractor.

 

You haven't really lived until you have seen the views through a high-quality 128-140mm apo.  Treat yourself to something from Takahashi, A-P, or TEC and you will create some very lasting memories.  cool.gif

Perhaps a used TEC140, but I still might be short some cash on that.

Thank you

I whent down the AP road for a while withering some successes, this discipline was not for me. The frustrations kept getting in the way f the pleasures.like spending the whole night taking subs that result in nothing for one reason or other. As soon as I tried NV, I put the AP in the box. There are incredibly smart and clever people here on this forum that are working on gizmos for AP that will turn your mount and scope and camera into something that is very Stellina like. We will see what the future brings.

 

HAPPY SKIES AND KEEP LOOKING UP Jethro

Hello Ron,

Thank you,

I agree the SCT's have only one virtue. They are compact. The two I have are the last SCT's that I will ever buy. The views are fabulous until you view side by side with a nice Refractor.

Those three companies TAK,  TEC, AP, are nice, I have been also looking at Stellarvue. And some others. That's when you start getting Research saturation and your Brain starts buffering. 

 

HAPPY SKIES AND KEEP LOOKING UP Jethro.

 

P.S. interesting here, zero mention of Televue.

 Sorry, my fault.  Blame it on old age!

 

Televue still makes wonderful scopes and I will always remember my TV-102.  Their  NP-127 would be an excellent choice.

 

Others to consider would be TMB and CFF, also.

What would you buy?

 

 

Since you're asking what would I buy and not what would I recommend:

 

I would buy nothing.  I already have it. For night vision, fast is good, for visual, wide is good.

 

For objects that require high magnications, refractors are underpowered.  RAK talks about pinpoint stars.  I'll take M80 resolved into a myriad of pinpoints.. 

 

I saw that Jeff Morgan just bought an NP-101. I suspect he had night vision in mind.

You were too quick for me.

 

My next refractor (if there is one) is the NP127.  

 

I don’t think there is a finer visual refractor for the kind of wide-field deep sky refractoring that I enjoy.

I am not sure about that.  I've never been impressed with any of the TV127's I have looked through, either casually or for longer periods of critical viewing.  I think I would choose either a a TSA120 or a used TEC140ED.

 

The TSA is really good and it will ride on the same mount that you would use for a 4" telescope.  I use one on a Vixen GP and a GM8.  I doubt you would notice the 7mm diff in aperture between the TV127 and the TSA120.  And, I am betting the TSA120 will have the better optical figure.  

 

The TEC140 would be bumping up against the $$$ limit, but maybe you could kick in a little extra and find a motivated seller.

If used for NV observing then you want something reasonably fast. AND if the same scope is used for high power lunar/planetary observing then you want excellent color correction and high quality optics. Those requirements lean towards apo triplets.

 

And since you already have some 100mm refractors, and with the $5,000 budget, one might consider these…

 

Stellarvue 130 F7: $4,995

 

TS-Optics PHOTOLINE 130 mm f/7 FPL53 Triplet Apo - 3.7" focuser: Chinese optics:
around $2,500

 

TS-Optics Photoline 140 mm f/6.5 Super Triplet Apo with “2 ED” elements: Chinese optics: around $4,000

 

Takahashi TSA 120 F7.5: $4,340

 

There are some 6” triplets available (Astro-Tech and APM) with Chinese optics for under $5,000 but they are F8 and, have course, larger/bulker so it depends on your mount and tolerance for setup and takedown.

 

Of course, the used market is also an option: There’s an APM 130 F6 for $5,500 right now on A-Mart that would be excellent for NV and visual.

 

I use a Tak TSA 120 with NV and love the scope for that use. It can be reduced to around F5.25 with an inexpensive Antares .7 reducer, or Barlowed for more focal length. The TSA 120 also has superb optics for lunar/planetary observing and at 13-pounds (bare OTA) is reasonably portable.

 

I also have a fast 4” refractor and a slower C8 that I pair for NV use. But when I want to take out just one scope, it’s the TSA 120.

 

Good luck with your search.

 

Bob
