250p QUATTRO Carbon Fiber version on EQ6R PRO mount?? - Forums

Hey everyone, I’m looking for some advice. I’m planning to buy the 250p Quattro telescope, but I’m concerned about the weight. With all the imaging equipment attached, it will be close to the load limit of my mount for astrophotography. I’m wondering if the carbon-fiber version of the 250p helps with this — does it make a noticeable difference?

If anyone has experience using the carbon-fiber 250p on an EQ6R-PRO mount, is it better than the non-CF version in terms of guiding performance? Also, from your experience, how are the frames coming out? Are you getting usable data, or do you often end up with star trails? I know wind can be an issue, but I have that mostly under control.

It will be lighter of course, as to what effect that will have I can’t say. The EQ6 is pretty rugged though so you probably will be ok. You could also try and lighten your rig and reduce moment arms as much as possible. Get the computer and other stuff off the rig, use OAG rather than a separate guide scope and so on.

The surface area of the newt is a larger concern then the weight. On a perfectly still night you’ll likely be fine with the eq6r but if any sort of light breeze comes along the guiding will noticeably suffer.

That’s even true with my 6” F/6. I do find that on windy nights, shorter subs are a godsend because you can get a lot of good frames between the gusts.

I am under the well-grounded impression that the CF version hasn't been on sale for quite a while, is it not? I used to run a much longer 10" newton (12 kg tube) on a GP/DX so I expect that you should be able to do the same once everything is finely balanced. But it would only work with no wind at all.

I use that telescope (non-CF) on my NEQ6 PRO mount and take 300-second exposures, losing very few due to guiding or other issues (approximately 1 out of every 30). I use an OAG.

My biggest problem is tilt, but I've recently changed the focuser and collimated it with the OCAL.

The NEQ6/EQ6-EQ6R mounts handle the Quattro 250p quite well, but as soon as I have the chance, I'd upgrade to a more robust mount.

So how much is your total weight coming to?

I am losing a frame every now and then even with my 10kg setup so i would be more than happy if i get the same.

ZWO 294 mm 410g

Quattro 250p 15kg

OAG-L 267g

174mm mini 60g

ZWO EAF 277g

ZWO 7×36"mm 500g (?)

vixen extra 300g

extras aprox 500g/1000g (filtros, cables, dew heater, primary mask

Total aproximado 17,5 - 18,0 kg

Carbon fiber tripods are a bit lightweight but I do like it with my AM5 and Askar 400 which is lightweight.
I have seen 3 strainwave mounts on carbon fiber tripods tip over at star parties. So you need to weigh them down in windy or otherwise conditions.

Looks like the CF tube version is 1 Kg lighter than the steel tube.

You can always buy the CF tube upgrade.

I very much doubt this is accurate.

The cf version comes in at 10 kgs while the non cf is 14 kgs.

I have not a 250 quattro, but also 10” Newton (TS-Photon) and EQ6-R.

Without wind I get a 0.5-0.7” guiding (with a poor seeing at winter). BUT! This is after 3d balancing, not only 2 axes! After this, such 10” carbon tube with EQ6-R handling really well with 0.5”.

Practically, it’s usable in 0-3m/s wind range. If it’s not a really light breese - the stars will be bigger.

P.S. Recently I received a cem120 and tri-pier 360… Made a test with my 10” newt and…… I have guiding bigger! 0.8-1” on cem120 instead of 0.5-0.8” on eq6-r….. Maybe some setting not optimal for cem120. Or -20 degrees celsius - problem for cem120, but not for eq6-r… I don’t know, need to investigate this.

Hi, please could you precise the weight of your 10 inch newton ? . I also have a EQ6-R PRO and I am asking myself if I purchase one 8 inch or one 10 inch newton (namely Skywatcher) . Some people said 10 inch are too heavy for EQ6-R . What is your feeling . I see that wind speed is of major importance but I do think it came from tube length not from tube weight ? What is your F/D ratio ? Hard for the collimation or stable after one final adjustment ? Thanks ! For the moment I calibrate with a low cost refractor (90/910 from Skywatcher) without guiding . (Cf. my post) . Thanks a lot

Hi again, could you please precise what do you mean exactly by 3D balancing ? Thanks

I have a 250 pds in steel. Have no problem with SW eq6r pro. I’m using an sw ed50 and zwo 120 mm to follow the stars. As long as you balanced it should be fine. I put my asair on it to. ☺️

I’m pretty sure the carbon tube cannot bring 4kg weight difference with respect to an instrument which weights 9,5kg in steel version, dovetail and rings included.

As it has been said, the gain will be in order of 1kg (about 10%). At 800€ cost.

But the tube will keep the same wind drag, i’m not sure it is worth the price. Depending of you observing site, you may consider to DIY a wind breaker gear…

For what its worth i already ordered the steel tube i think its not worth the cost to benefit ratio.
