Short focus Apos look funny. Sure, less space- but less beauty, less grace!

I don't mind the looks, but they can be hard to balance, because the tube is so short, the point of balance often lies somewhere in the focuser - or even behind it! I also don't particularly like that if I want to reach high magnifications I need to pile on the barlows. 

 

Some say that the most useful feature of the short focal length apo is their ability to give a very large field at low magnification. That's fine, of course, but I rarely use that feature, preferring to use medium and high magnifications and here a longer focal length is preferable. If I want very low magnification and a large field, I use binoculars. 

 

 

Clear skies!

Beauty is in the eye of the beholder.  But function is in the nuts and bolts.  APOs are beautiful to me because they take up less space, are less cumbersome for grab-n-go, have a wider range of fields of view and the color correction is better.

Howay The Bruins!

Skylight carton lens 60/1000

This can do some damage on the moon and Jupiter too.

The 10.5mm plossl gives a wonderful 95X which is just right for me.

Howay The Toon Army!

 

Nice Skylight.

I suppose the 70mm f10s are ok but better color correction occurs with the 70mm f12.8 ;that additional 200mm tube length is worth it..Besides,for low power wide views the plentiful 70/400 can be piggybacked onto the 70/900.

 

The Zhumell Aurora 70,a Galileo whose model I don't recall,and the Vixen a70lf have all given very nice seemingly true color views here at Foggy Valley.

While I don't use super fast APO's, both of mine being F7.5 and F8 and 76mm diameter objectves, I've really come to enjoy the light weight and high magnification capabilities of both my 3" apos. They get used more often, thus they see clear nights more often than my former 4 and 5" apos ever did. My back has thanked me alot too!! After 50 years and many larger scopes, I'm much more inclined to go out every clear night and observe with my 3 inchers!!  Setup is easy and they can be quite easily transported to dark skies. Grab and go astronomy at its finest!!

Ah then,perhaps the 100mm F9 apo might delight your eye-looking at AND through !

After considerable thought and reading way too many threads I ordered a tv-76 today. Almost bought a tak dsu but I wanted something I didn’t need to disassemble that was truly grab n go. Really looking forward to the 5 degree fov.

There’s a range of grab-and-go-ness. Here’s my Stellarvue SV-80S f/6 on a stable Discmounts DM-4 Mount; my most often used scope and mount combination. Have fun with your TV-76!

Hooked on small scopes, I did about a year ago, found out the smaller scopes are more fun to use, better on my back, easier to move around, and some of them have great optics. Look what Galileo had, look how much fun he had, I bet he would have loved to have had a 60mm Jason.

I've never enjoyed binoculars, despite multiple attempts at it. My replacement is a 50mm f6.6 apo with a 40mm 68° EP that gives me 10x mag and an 8.25° fov. That, for whatever reason, I highly enjoy. It's great for sweeping around, compact travel, and if I ever get around to it will make a great companion for my 102mm f11 ed.

I only use binoculars for very wide field sweeping, which I rarely do anymore,preferring  instead to use my 76mm F8 Apo for the brighter deep sky objects.

The TV-76 was my favorite small scope.  I think I have owned 3 over the years.  Problem was whenever I need cash, it was the easiest to sell....I now have a StellarVue SV80 Access, which is a nice scope, but wish I still had the TV-76.  Here's a picture of my last one....

Well as I posted earlier a tv-76 seemed to be in my future and I ordered one. Then waited ...... on back order. Called Televue who informed me wait time could approach 2 months. Called all the online shops. Nothing available.

Cloudy nights classifieds to the rescue. Saw ad for lightly used pristine fc76DCU and decided to pull the trigger. With the money saved will get the 1.7 extender.

So lord willing and if the creek don’t rise I’ll have a dcu next week.

You won't regret it.  It's a marvellous little scope.  Had mine for about 18 months or so, initially bought as grab & go and travel kit, but it's rapidly become my favourite scope, to the extent that I've gradually been selling off the larger kit as it hasn't been getting any use!  My back loves the lack of weight, and my eyeballs love the view.  The 1.7x extender is well worth it for lunar alone.  Have fun!

I used to believe that as well...wide field use binoculars! However, the first time I put a 💯 degree eyepiece in my new Stowaway, I had an epiphany when the scope just got out of the way and I had the “spacewalk” experience!! Then, after hours of “walking” I sprinted to high mags for views of the planets...binoculars can’t do this. Short apos excel at it!!!

That’s unfortunate regarding the TV-76 (I love mine), however a Tak of any flavor is almost never a compromise.  It truly is hard to make a bad choice in today’s age of ED/APO refractors.

I shall console myself by buying the 1.7 extender and looking at Luna and planetary views at f12
