TS 65mm f/6.5 Quadruplet Astrograph and DSLR?
« on: 20:35:25, 12 December, 2014 »
Hi all, has anyone got any example images taken with a Teleskop Service  65mm f/6.5 Quad and a cropped sensor dslr?  This scope is at the top of my shortlist for the new year, but I'm struggling to find some images taken with dslr's (plenty out there with ccd) and I'd like to see how it performs with a dslr chip for comparison

also, those of you who understand the ratio between f/l and pixel sizes, is this scope a good match for my dslrs?  I use a 500D for my astro stuff but also have a 700D

Thanks
Ade

I would be very interested in the responses as i most certainly considered this scope but was admittedly scared off a bit due to the  horror stories I had heard regarding pinched optics. i am aware that a couple of people on here use them, very successfully. I will in time move to a CCD, just not anytime soon.

Ian, I resist the ccd simply because 1, I cant afford one, and 2, I cant be arsed with the faff of all the processing which comes with combining all the filteration.  I know that that is the only way to produce excellent astrophotos, but I'm not patient or technically inclined to do that, so I'd like to see what this scope can do with a basic imaging system, like mine

From what I read, the pinching optics was only a problem with the first scopes, so that issue dosent wory me,  I'm just interested in how a dslr performs behind one of these

For another £100 you could have a W/O Star 71 which is producing some really nice images. Not knocking the 65 Quad but there are a few choices.

Would HIGHLY recommend the Star71. Can't comment on the 65 though.

Can highly recommend the 65q Ade.... I did put my DSLR on it when I first got it but it wasn't on a tracking mount so no images worth posting (not that I think I actually kept them).  I have also used is a few times for day time imaging with the DSLR and got some lovely images out of it with no sign of vignetting.  If I can find them I'll post up.

Can't comment on the WO71 but they do seem to be getting good reviews too.  It's all going to be down to field of view and focal ratio and whether that's worth another £250+ [£789 vs. £519]...

Hmm, I'm now thinking towards a canon 70-200 f4 L  -  :crazy:  has the option for general photography so may be a more practical option in the long run

opinions?

I have both mate and love both of them.... it all comes down to focal length at the end of the day. The 65q with 420mm vs. the 200mm of the Canon L.  I have to say I've only used the 200mm once or twice for astro and never really got a satisfactory image (more to do with the fact that I was using Chris's SX M25c with a "mog" type adapter which wasn't orthogonal so got dodgy stars).  Also, 200mm is really wide so starts to reduce the list of targets quite a bit.

I have however used the 65q for terrestrial stuff and it sings (just a bit of a pain having to manually focus so not very good for any moving at speed  ;) ).  I've also done solar white light with both scopes and the extra focal length on the 65q win out there.... all in all mate, if I had to choose I'd get both the 65q IMHO  :-*
