Easy Balancing the Sky-Watcher Az GTI

The Skywatcher Az-GTI is a great little and affordable computerized mount for astrophotography.
But rotation, particularly in the azimuth movement (the RA if you use it in equatorial mode) is often stiff. So stiff that balancing the payload is not possible.
The hard way to fix this is open the mount, tune it, grease it, etc. But for the faint of heart, here is a simple strategy to balance the payload once for all.

To balance the AZ, you put all the equipment + weight. Then in the bottom 3/8” you screw a hook and then you put all upside down and put a cable to the ceiling:) Then you move the weight until it’s horizontal… this is very precise

Thank you Andrea, I've followed your guides and tuned my AZ-gti to to guiding within 1.5"... It's really quite a capable little mount.

Ciao Andrea, ho appena comprato l'az gti e il kit per farla diventare equatoriale. Ho un problema.. con l'app synscan ho provato a fare i movimenti manuali e si gira correttamente per esempio se premo il pulsante a sinistra sull'app. Se premo il pulsante a destra invece sento il motore che fa il movimento ma la montatura resta ferma... che tipo di problema è? Anche un mio amico che ha appena acquistato una eq5 ha lo stesso identico problema... grazie mille se ci darai una mano, mi sono guardato praticamente tutti i tuoi video, grazie 🙏

1.- Set the polar axis to 0º (or as close as you can); 2.- Release the RA clutch; 3.- balance with the counterweight; 4.- returns the polar axis to its original position. One minute setup.

Hello friend, this is Anderson from Brazil and I would like to thank you for the content presented in this video. I have some doubts, I'm going to start astrophography and I don't have anything, would you indicate this configuration to start? or indicate another one with a cost benefit. - skywatcher telescope Evoguide 50DX - EvoFF v2 - Field Smoother for SkyWatcher EvoGuide 50ED - mount skywatcher star adventure gti - camera asi294 color or asi294 pro color or asi593 pro or asi183 or other that you indicate? - I won't buy guiding telescope and cameras for now. - filters what does it indicate? in my city botle 8 with these settings can I get good images and good exposures of up to 60 seconds? thank you very much!

Hi, great video, can I ask, is that an ADM saddle on your Az Gti? I just got a dual saddle and the adaptor plate goes on fine but the actual dual clamp onlt affixes vis a single centre bolt? There are other tapped holes in the clamp and it is supplied with two bolts but only the centre hole aligns. Just trying to find out if this is correct before I go ahead and clamp my scope to it. Thanks.

A quick way is to weigh each side on some bathroom scales and with the distance from the ra axis to your optical axis, the counter- weight distance is given by the moment: dist_cntwght * mass_chnwght = dist_ota_axis * mass_ota

if the max payload is 5kg, I can put a counterweight of 5kg on the other side and that's ok?

Ciao Andrea, grazie per i Tuoi video, sempre interessanti! Vorrei chiederti di più sul dovetail ADM. Oltre ad essere più sicuro dell'originale SW, offre anche più stabilità e meno vibrazioni? Lo hai ordinato da firstlightoptics? Saluti, Marco
@andreaminoia2002

Grazie ! Sicuramente offre più sicurezza e stabilità. Sul guadagno per le vibrazione penso sia pressoché nullo in confronto a treppiede e wedge. L'ho comprato su astroshop.eu www.astroshop.eu/mounting-plates-and-rails/adm-prismenklemme-fuer-skywatcher-az-gti-montierung/p,64600

Ciao Andrea, volevo chiederti se hai qualche suggerimento per l'autoguida, siccome questa perde la porta ST4 rispetto allo Sky Adventurer se c'è qualche possibilità. Avevo letto di un giapponese che aveva fatto un adattatore per la porta RJ del AZGTi e volevo vedere se trovavo qualche schema in giro per costruirmi qualcosa. Per la polare come hai ovviato? Ahimè manca il cannocchiale polare, va adattato un cannocchiale polare con un supporto 3D? tu come hai fatto? Grazie
@andreaminoia2002
@andreaminoia2002 2 года назад
Per guidare puoi usare l'asiair in Wi-Fi o via cavo eqmod. Un cavo eqmod serve anche per usare il laptop al posto dell'asiair. Il cavo del giapponese penso fosse una cosa sperimentale per compensare il backlash in declinazione. Io ho solo un banale cavo eqmod. Per il cercatore io non lo uso perché con la camera astronomica faccio il pare solving. La app SynScan pro ha una procedura di allineamento alla polare che non richiede cercatore. Altrimenti si, serve un adattatore

Hi, I got 2 questions: Where did you get the counterweight bar from? And what product is the tripod ring for your Samyang Lens? Thanks!
@andreaminoia2002
@andreaminoia2002 2 года назад
Hi. The counterweight bar is from artesky. I got it from teleskop-express.it but is not cheap. For long time I used the simple threaded rod you see in the video. But the bar is extremely well made. Still, on the expensive side. The ring for the samyang is the William optics ring for their Redcat, with the handle to mount a guiding scope mounted on a classic dovetail bar.

Hi Andrea, thanks for the video and your explanations! I have the AZ GTI and use it for observing right now, as well as for doing some very basic "Astrophotography" with my smartphone. In the future, I would like to but it into EQ mode and start with astrophotography (as explained in your other videos, thanks for that as well! :) ) So a very beginner question: Do I have to take the weight of the counterweight shaft and weights into account for the total weight I can but on the mount? So can I but approx 4-5 kg on the mount + counterweights, or is it 4-5 kg max including the counterweights?
@gazza9839
@gazza9839 2 года назад
Hi Andreas, usually mount specs are just the payload and ignore the counterweights.
@andreaminoia2002
@andreaminoia2002 2 года назад
It is debated. This mount is intended to be used in alt-az mode, not in eq mode. Equatorial mounts need a counterweight so the payload capacity listed is in top of the counterweight. Some people report that skywatcher said we have to count the counterweight as part of the payload for the az-gti. But alt-az mounts benefits too from a counterweight so I tell you that my experience is: 2kg counterweight, 3.5kg of imaging instrumentation based on a celestron c5 reduced to 900mm and the az-gti does not even break a sweat. Guiding this setup allows me to shoot 120s subs with a keep rate of about 70%. Just 20% worse than my neq5

Ma quando metti il supporto a coda di rondine sotto, in pratica non va a toccare il cilindro mobile? voglio dire se si blocca sotto avvitando la vite a 3/8 fotografica sulla filettatura sotto della AZGTi, questa come fa a muoversi. C'è qualcosa che mi sfugge. Forse la fa muovere tutta in blocco in pratica?

io avevo lo Sky Adventurer ma non mi piaceva tanto, lo vedevo come un oggetto del passato, con la motorizzazione solo in AR e poco comandabile. Ho preferito passare da poco tempo su questa, più carina, più compatta e più integrata con ASIAIR, Stellarmate, Astroberry, PC ecc... inoltre ha la motorizzazione in Declinazione che non è poco. Manca il cannocchiale polare ma ci si può adattare qualcosa in 3D o anche laser.
@patrickpat5277
@patrickpat5277 2 года назад
un altra cosa che non ho capito è come sia possibile che con la montatura AZGTi si riesca a fare astrofotografia visto che supporta un carico massimo di 5Kg, ora nelle altre montature equatoriali si parla di non più del 50% da caricare tra OTA, telescopio guida, telecamere ecc... mentre qui si va quasi a toccare il limite dei 5Kg. Boh. Ok il contrappeso ma
