Hi,

 

I've posted on SGL but searching around on Google there seems to be quite a few people on here with Tak's so thought I'd ask here as well.

 

I've been trying to decide which Tak to buy for 2 weeks now ! I've had loads of help trying to decide yet I've still not ordered one. As I'll be using it on a Fornax Lightrack quite often for lunar imaging I THINK I've ruled out the FC100 due to size/weight even though I will also be using a HEQ5. Looking around on astrobin there are some excellent lunar images using the FS60CB and with my 178MM gives me a full disc without doing a mosaic but I'd probably use the 1.7 extender giving me f/10 BUT then I can't get a full disc using my 178MM ! If I upgrade to the 174MM this gives me a full disc using the extender BUT now I can easily get a full disc using the FC76DCU with the 174MM at f/7.5. I can't seem to find many images on astrobin using the FC76 ?

 

The FC76 isn't much bigger or heavier than the FS60.

 

I would also like to use it for observing on a alt/az mount and I have the Altair Astro Starwave mini mount so I think the FC76 with 1.7 extender is going to be the maximum payload, I think the FC100 is going to be too heavy ?

I'd also like to do some planetary imaging but I know it's going to be limited due to aperture, with my 224MC and the FS60Q it's a reasonable image even better with a x2.25 barlow obviously it's better with the 76 but how much better ? Am I going to be disappointed with the planetary imaging/observing with a 60 or 76mm aperture ?

 

On my Lightrack I normally use the Manfrotto 410 geared head which allows me to move my dslr to get perfect framing, I'll probably need to use the counterweight kit with the 76 so framing things will be a bit fiddly unless I use something like the ADM mini max guider mount which will allow me to fine tune my framing but this is just more cost and weight then I'm up to the cost of the FC100. I could probably just use the FS60CB and Q on the 410 head ?

 

How does the FC76 compare to say a cheaper 100mm ? Will I be wowed looking through the Tak ?

I thought I had decided on the FC76 and extender then if I got a 60 I've already got the extender if needed plus I could use the 60 for wide field DSO. The 76 and 60 are also much easier to travel with if needed.

 

I don't normally have this trouble deciding !

If you've already found f/10 to be acceptable to you for imaging, the great advantage of the FS-60Q over the straight FC-76 is the Q's flat field. Also the color correction approaches FOA territory in Q configuration. Visually it's excellent, too. I own both FOA-60Q and FS-60Q. The FS is very light, compact, easy.

 

The other unmentioned alternative that will check your boxes is the FSQ-85ED. It's heavier, but the short, fat tube and quad distribution of the glass might make it OK with your mounts.

 

You can, btw, make a "FC-76Q" by combining FS-60CB + 1.7Q Extender + FC-76 Objective, or FS-60Q + FC-76 Objective. But now you are both heavier and longer, complicating your mount concerns.

I recently purchased a FS60c with the Q extender. I also own a 178MM and a 224MC. However, due to a combination of poor seeing and cloudy weather, I haven’t been able to image with it.

I won’t be able to offer much help, just a few thoughts.
I probably will not do any planetary imaging with the FS60Q. The aperture is quite small and if I’m setting up my medium eq mount, I might as well use my 4” apo. Deep sky is another matter, but I feel that the 178MM sensor is too small to fit many of the larger DSOs with the Q extender attached. I only purchased the 178MM for solar imaging, but if I were to purchase a camera specifically for this scope, I would go for the 174 instead.

Since you already own the 178, I would consider the FC76 + flattener (no Q module). Or perhaps the FOA-60? Or another option is to purchase the FS60Q and the FC76dc screw on module. This essentially gives you 4 scopes in one. The FS60CB, the FS60Q, the FC76DCU, and a FC76DCU with the Q. Whew...that’s a lot of letters.

I’ve had a fair bit of visual time with this scope - all my visual is done with the Q extender attaches. For the size, planetary views are quite good. Jupiter at 120-150x looks quite nice with steady seeing. Bands are clearly defined and the lighter clouds can barely be seen. It’s also quite fun to hunt down DSOs with limited aperture. From my bortle 8 backyard, the dumbbell and ring are visible with a UHC filter.

The reason I went with the 60 is 1) it’s the perfect size for airline travel and 2) if I purchase a FC100, the 60 won’t become redundant. The 76 on the other hand would be very close in size.

With that said, I’m tempted to purchase the FC76 module to use when not traveling by air, but it can wait. I’m still having lots of fun discovering what 60mm of aperture has to offer.

This was what I had been considering, get the 76DCU and get the extender later on then if I want to get the 60CB later for DSO. But like you say the 76 is very middle of the road so would I want a 100 and the 60, maybe a 60 and a 100 is a better selection to have to star with.

The FC76 is a very nice scope.  Takes power well and is a good grab and go scope.  Excellent optics.

I agree!!  I have a 32 year old Tak FC76 and it really takes magnification well.

Hard to beat Fluorite lenses.   I treasure all the Taks I have. Seems foolish to sell one in that they perform that well.

I have the Tak FC76 DCU and am very happy with it.  Very sharp optics and lightweight.

I have the FS-60Q, acquired a few months back. It’s a “convertible” but I’ve only used it thus far in Q mode. It’s very light and the quality of construction is apparent. I had it out late Friday night with the AT102ED and my C9.25 - all loaded on my ES T2. Not a great night for deep sky pursuits with a near full moon and clouds continuously rolling through but Jupiter was largely available as were numerous doubles. On Jove, the C9.25 was providing fantastic views especially watching one moon slowly emerging from behind the limb - I powered up to 427x with my ES 5.5mm and to 360x with my Morpheus 6.5mm. Amazingly the Q was giving a sharper more contrasty view, albeit smaller and dimmer using my ES 4.7mm for approximately 128x and a simply beautiful view with the Morpheus 6.5mm for appx 92x. The emerging moon was visible at 128x but not so distinctly. The AT102 brought up the rear - very good mid-power views but high power was not on par with the Q or C9 ... but still a very satisfactory view.

 

My only nit with the Q thus far is the focuser - it’s very good but it could be a bit smoother/buttery. A double speed would be so nice...

 

Clear skies!

I have the feeling that the SGL discussion has ruled out the FC-100 (of any focal ratio) for the OP.

Make it conscious. I did and it was a good choice.

I own the FC100DF and the FOA 60. I had a FC76 DS but I sold it to refinance the FC100. All three are marvelouse scopes with a fantastic optic and  light weight . The 76 DS version was a little bigger than the DC because of the 95mm  tube. So the 100 DF is not much bigger when the dew shield of the 76 DS is extracted. The FOA 60 is the most grab and go and shows many more than you expect from a 60mm scope. And it is the cheapest of all .

I only use my TAK s visualy but the views are breath taking. I think it is a personal choice if you go with a 60,76 or 100 er TAKAHASHI. You wont regret.

Clear skies Markus

Yes, you will be wowed. By any and all three of them. FOA-60, FC-76 or FC-100. Just choose the size that suits you, your primary uses and tripod/mount best.

Anyone got a picture of the FC-76DCU with the extender attached (f/12) next to a FC-100DC ?

Is there any difference in quality between the 60 with 76 lens cel substituted, and either of the standard 76s?

How does the FC-76DCU compare against the Skywatcher 100ED ?

If you are thinking 100mm again, the FC100DC is better than both.

 

A SW100ED will be heavier and longer. Optically they are very good, great value for money. Being F9 makes for an eyepiece-friendly scope too, as less elaborate/expensive models will be compensated for.

I was wondering how the 76mm of the Tak would compare against the 100mm of the SW. I tempted with the 76DCU but I have looked at the SW100ED before. I'd love the Tak FC100 but the price is now just going up and up plus I could take the 76 on holiday.

The Tak 76 would be an excellent travel scope! Not such light gathering as any 100, but comparing it with the SW ED, it would be as good.

 

Otherwise a Vixen SD81 would be a good alternative to the Tak.

Possibly as good on the moon and planets but the 100 would do better on DSO's I would think ?

 

(I'm thinking of how my ED120 compares with my FC-100DL)
