New Skywatcher Solarquest mount

[c8er]

Has anyone tried the new Skywatcher Solarquest mount, which claims to find and track the sun automatically? If it works as advertised its inbuilt solar auto-guiding/tracking could make it a useful mount for lightweight solar setups (stated load capacity of 4kgs).

Link here to APM telescope's webpage for the product (Skywatcher USA don't seem to have it listed but Skywatcher Europe, Canada, and Australia do).

It seems interesting for outreach.

Interesting that someone thought about it...

Agena Astro have asked Skywatcher USA if they will be selling it, and told me the answer was, no they won't.

I wonder if it will stop tracking when the sun goes behind a cloud?

[pedro]

I ordered one and I guess I will have it this week. I will keep you guys posted.

For 300 euros it is difficult to ask for more

[marktownley]

That was my thought too Pedro, I quite fancy the idea of something for quick grab and go full disks that I can just carry the scope and mount out in one go (in between the clouds!) - be interesting how you get on Pedro. You don't have clouds where you are very often so give it a try covering the sensor with your hand and see if it stops tracking for me.

The only other thing that concerns me is payload, not sure it would take my 60mm scope with DS 50mm etalons on...

The answer is in the manual:
2.3 Envioremental Influence
1. Clouds, especially thick or low clouds might reduce the accuracy of auto-pointing. They might also lead to visible drift of the Sun in the eyepiece while the SolarQuest is tracking the Sun.
2. Strong reflected light, which happens to appear within the SolarQuest’s searching path, can terminate the auto-pointing routine unexpectedly.

Thanks Bart, I thought that might be the case.

The payload is 4Kg, I guess it will hold your 60mm scope Mark

My solarquest mount arrived today. Unfortunately I will not be able to use it during the next weekend

Added remote focus so that everything can be done from indoors now

How good is it for tracking prominence animations?

Martin

Hi,

I do not have one but as it is a Alt/Azi mount the limb of the Sun will rotate ...

[Martin_S]

Thank's Rainer ,I've been attempting solar animations With LuSol but I keep getting Image drift ,I'm looking at all options at the moment.

Hi Martin,

My experience from the last months with a CEM 120EC2 whch has a quite good tracking is that Solar tracking in regard to keep a spot in place is quite difficult.

Now the Sun is low and I am using custom tracking values and even so the sun drifts in RA. You will always have a drift in DEC day by day as the Sun moves in DEC ~ 45° in 180 days and then back again.

In regard to RA tracking I ahve seen that my custom tracking rate for RA varies over 6 months e.g. when the Sun in the Winter is Low and in Summer it is high. Also when you approach the horizon tracking rate must get slower and slower ( famous King Rate ) due to the refraction and all objects seem to move slower ...

I did built a Sun tracker which was connected to the guide port of my old Losmandy mounts but accuracy was a problem and after getting the new iOptron CEM 120EC2 mounts my Sun guider was obsolete as the mounts tracks better then my Sun guider was able to do.

Thanks for posting this Rainer, i've never thought about it like this before.

That drift in declination is about 0.25degree per day, and that doesn't factor in the obliquity or eccentricity of the Earths orbit, which means the rate varies throughout the year too. Likewise for RA.

'Solar tracking' on mounts is just going to be a slightly different rate than sidereal rate, and won't factor any of the above, the drive will just track in RA at a continuous rate, regardless of time of day or year, with the DEC axis just sat fixed.

No wonder we have drift in our animations, just in DEC this amounts to 30 arc seconds per hour! (on average!).

[Martin_S]

Thank's Rainer and Mark. I'm in the process of building a sun tracker, if it works I'll post the results in the mods section . Meanwhile I am going over to the darkside to practice guiding at night with PHD2 as I've not done guiding before.

I'm hoping that my new 10Micron GM1000 HPS GEM mount will have good solar tracking year round and at most altitudes as 10Micron say in the manual that if you use the mount's "Follow Object" tracking method (different from the usual standard solar/sidereal/lunar rates also in the hand control) that the mount will account fully for the object's proper motion in its sophisticated tracking model to custom track any solar system object, including the moon/sun/planets, and also asteroids and satellites if you have freshly updated the mount's file of current asteroid/satellite paths. The mount includes refraction effects in its modelling/tracking using temp and humidity inputs from an electronic weather unit I have plugged in to it (updated only on a slew of the mount so it doesn't cause jumps during tracking if the weather parameters change while tracking).

The mount by default tracks in both axes to make use of its sophisticated model and to still give good tracking with some amount of polar and other errors.

This is what the manual says about the "Follow Object" tracking option. "When this function is active, everytime you slew to a celestial object from the database, the apparent proper motion of the object is computed, and is set automatically as a custom tracking rate.
This is effective for all solar system objects, such as asteroids, comets, planets, the Sun and the Moon."

I haven't had a chance yet to try the mount for solar daytime work, only night work so far, but I am hoping it might even give good enough unguided tracking for solar animations, as it does so far for me for unguided deep space night imaging.

I also now have one of these little Skywatcher Solarquest mounts, and it certainly tracks the sun well for hours, and keeps itself well enough centered on one solar surface feature long enough for the usually short non-animation solar imaging runs. I wouldn't try it for time-lapse animations due to the Alt/Az field rotation, and it doesn't work for me on an Eq wedge sadly - I tried that. From memory I think it wouldn't even initially find the sun automatically, or if it did it wouldn't then track it correctly. My memory is bit hazy on which the problem was exactly, but it didn't work.

As the topic is current I thought would chip in; i'm going to get of the solarquest heads. I bought the AZ GTi mount https://www.firstlightoptics.com/skywat ... ripod.html initially on the grounds I could also use it as a grab and go for the occassional night time stuff I do. While it is great for night time it is a PITA for solar, it really doesn't want you to look at the sun easily or quickly using it. Have wasted so many sessions this winter when the sun has been in gaps in the trees and the mount has been an pain to get running. So, will pick up the solarquest next week instead...
