Sky-Watcher Dobsonian 16 Inch Synscan Go-To

[@PetraKann]

A 16" mirror will collect about 78% more light than a 12" mirror (presenter said 35%). Relative Light collection is related to the ratio [Di^2/Do^2] where Di and Do are the diameters of the two mirrors being compared.

what if we wanna try to find intelligent civilizations with it, do we then use the Drake equation: N = R*fpneflfifcL? 🤓🙌😂😁

[@projectnemesi5950]

The additional light lets you cut down on exposure times in astrophotography. What is more important for pure observing is the aperture size and magnification of your overall system. A larger aperture size will create a smaller PSF (for the ideal lens/mirror its an airy disk PSF). Higher magnification zooms in on those PSF. Your eye can not really take long exposure to gather more light, so you want to maximize what your eye can do in this instance, and its increase magnification and lower PSF size (increase resolution).

I've had mine for about 18 months now and have had no problems with it. The two star alignment is easier if you fit a Telrad finder in addition to the optical finder but once set up it tracks well and usually finds objects even within a 10mm eyepiece giving a power of 180X. All the equipment is there to do DSLR photography out of the box(apart for the M42 converter ring) and with my Canon 1100D have imaged stars down to about 15th magnitude without serious trailing.Its allowed me to produce some lovely images of a wide range of deep sky objects and doubles like Rigel. Admittedly it does make a bit of noise when slewing at full speed but because of its decoder system this is seldom necessary. The mount is virtually silent when tracking. A shroud is highly recommended as it affords protection from dew and falling eyepieces,but annoyingly these are quite expensive for some reason. Its a lovely scope for the price I only wish there was more clear night in my area.

@@Mandragara HI There, My scope is permenantly set up in a sliding roof observatory,Im afraid the 16" Flextube is far too heavy and cumbersom for regular transportation. I think that would go for the 14" as well.The 12" is probably about managable but I would personally recommend you restrict yourself to the 10" in your circumstances. It would be far better to go for a smaller aparture than miss observing opertunities because of setup difficulties. Good luck. Les.

[@Mandragara]

@@starsnstuff842 Cheers! So what's the issue with transporting lager scopes? Is it just the weight? Or do they damage themselves under their own weight easily? I can easily lift 30-40 kgs above my head so when I see tube weights of like 25 kgs, it doesn't seem so bad, or am I just naive?

[@vancedburner8052]

@@Mandragara It's the size more than the weight. I have a 10 inch tube dobsonian, (non goto) and while it is easily within my ability to carry the weight of it, it makes it challenging when the points to lift it are near the centre, meaning that you are holding the weight far out in front of you. Try holding a weight equivalent to that out in front of you, you'll find it's much harder than lifting it up close to your body. But also, I don't own this scope, I'm just guessing from my 10" experience

HUGE mistake at around 4:13 ...16" mirror will collect 77.7% more light then 12" mirror not 35% as it is mentioned in the video. This is misleading, serious advertising error that may discourage potential buyer to make a purchase if buyer will not cross reference that info with other source. The mistake of that magnitude should have been mentioned in the description of the video.

And you can adjust the length of the focal lenth to acquire prime focus photography or observational focus, without using various types of adapter tubes ?

[@jeffsaffron5647]

No, focal length is determined by the curvature of the primary mirror. If you don't extend tube all the way some of the light will miss the secondary mirror.

I have the 10 inch truss tube dob from skywatcher. I was wondering if i can mount it like the one you have there on an eq mount? Would it balance on declination? What aperture is the one i see in the video?if it doesn't balance could i lower the truss tubes to the middle position and extend the camera 10cm from the focuser? Please help me because i can't buy an eq mount and a second scope for astrophotography at the same time. Would the neq 6 skywatcher manage it?

[@TANGOCHARLIE7377]

What would be the eyepiece height of the same model but 10 " size instead?

[@GerardsCorner]

4ft or 1.2m high pointing straight up. I sit down on a chair to look through mine most of the time. The optical tube assy on it's own weighs 15Kg which is heavy enough for most people, including me. The stand is considerably lighter. Both fit easily into a small car too. Please note the 8"-12" models only have course focusing, not fine as well. I get great sharp images from my 10" scope, even with modest eyepieces. Just make sure you collimate it properly to start with and then you only need to re-collimate each setup by tweaking the extension arms when you open it up as these are what go out of alignment between viewings, not the mirrors! It saves you a lot of time on each set up. I apologize if I have over answered you. Cheers.

Good quality scope. The base can be disassembled to make it easier to transport. The finder scope is straight through, and is inconvenient. The focuser, as he said is smooth, but it takes some adjusting. Use the extender tube. Sorry to see that both eyepieces are 1.25", it would have been nice to get a 2.0" This is a BIG scope, do NOT move it by yourself. You will likely need a ladder to work with it. And don't forget that open truss. You will need to add some poles or rods and place a cloth to absorb stray light.

Metal polish will completely destroy mirror, that's not how you make it shiny. Likely your mirror is old. Mirror must be recoated every 10-12 years more or less, if not you running into possibility of damaging surface. Telescopes cost a lot of money and you really need to learn more about your hardware.

Can a really big aperture on an Alt-AZ compete with a quality Eq with low aperture ? Imaging deep sky and some short exposures of the planets, stacked.

Then the only question remains how big should a deep sky OTA have to be to get good pictures of the most popular nebulaes, clusters and maybe double stars. A big bright Dobsonian might be the only way to look at the night sky with the naked eyes and Only seeing colors above 12 inch aperture ?? Should I get a 9.25, 11 or 14 inch SCT for photographing ?

[@kdanagger6894]

The three parallel tube design is cool for collapse-ability, but the lack of rigidity is a *huge* drawback. You need to keep the upper cage as light as possible, and keep all component weights up there as light as possible. Not easy to do since most everyone will he using heavy ultra-wide field eyepieces. When moving the telescope through it's altitude range the flex in the upper end causes significant shifts in pointing accuracy - and more importantly - major shifts in collimation. A three tube parallel truss design demands very beefy tubes. The tubes used in this scope are simply *not* up to the task.

Thanks for the video. *Skyliner* 400P? Oops! I was hoping to see the rocker box being collapsed. Oh well. I notice there doesn't appear to be a centre spot on the primary. I would have thought that was essential because these collapsing telescopes need to be collimated every time you set them up. Also, how does a 16" mirror only provide 35% more light gathering power than a 12" mirror? Not taking into account secondary obstruction because I don't have the data to do so, a 16" mirror is 77.77% larger in area than a 12", so the extra light gathering power should be of approximately the same order. I have dual-encoders on another one of my mounts and it really is a fantastic feature, but while this does seem like a very nice scope, I think if I would have to use a step anyway I would probably get a 20" and make it really worthwhile.

[@mrdoofa9357]

It does have a centre mark to aid collimation although despite the flextube name and how it works they hold collimation surprisingly well and the whole thing is very rigid in use. The presenter here made an error with the light gathering power, a 16” will collect 78% more light than a 12”.
