ZWO EAF ROBOTIC FOCUSER

DomAstro

Great focuser

Great focuser for the cost. I use with both asi air and mini pc running Nina.

ZWO ASI2600MM DUO [MONO]

James

Highly recommended all in one package.

I have been using this camera for just over a year now coupled with a ZWO filter wheel and a Baader filter set. I have been really happy with the results. The camera is fast and the images are very clean. A huge improvement over my last camera. No issues using the inbuilt guide camera through the filters - N.I.N.A. / PHD2 always finds multiple stars to guide on. The inbuilt guide camera really simplifies my setup. I highly recommend this camera. Examples of my images here: https://deepspaceplace.com/images.php?sort=&filter=ASI2600MM

CELESTRON f/6.3 REDUCER FOR SCT

Jaydn

Excellent service, excellent products.

Very happy! The staff were super helpful, and this won't be my last purchase from Testar!
Would you get the same product from AliExpress? Maybe, but
Optics are so sensitive to alignment and QC issues, I just didn't want the headache of anything being wrong with potentially replica products. With Testar, you're getting good quality products with excellent support!

The extra backfocus distance over my Meade 4000 unit is very much appreciated!

I don't own an observatory so a three hour set up

I don't own an observatory so a three hour set up (250 f4 truss Newtonian on a g11 mount plus camera and guide scope) requires me to leave the setup outside during the observing window. This cover, the large, allows this. It fits well. The only addition I could recommend would be Velcro straps on the apron. My setup is outside Tamworth. I face hot weather and thunderstorms. A permanent observatory is my next step, but this cover dampens the urgency. My setup includes a large camera on the side of the Newtonian. The cover is large enough to include leaving the camera on, near focus, and ready to go the next night.

Outstanding!

I have a long history with telescopes and astronomy, yet this device has blown me away. At half the price of my first Celestron and incredible results this purchase has been a revelation. I have awesome service from Testar and am loving exploring the sky with the S30.

SEESTAR S30 SMART TELESCOPE

Alan Brockman

Beautiful workmanship and lightweight

Beautiful workmanship and lightweight being carbon fibre. It attaches to my truss OTA with their mounting bracket and allows for precise adjustment and alignment. It has an impressive amount of brightness adjustment but my only gripe is that the panel is so bright I need to set it on its lowest value. Had I known I would have got a neutral density filter for it. It’s pricey but it takes one more tedium out of taking flats as it can be automated in management software like Sequence Generator Pro. Highly recommended!

Best of Newtonians !

Fantastic scope. I was about to import Apertura Carbonstar 200 from High Point Scientific but got to know they are basically rebranded GSOs, so went ahead with the local purchase. It has a very solid EAF ready focuser, the OTA is very lightweight and holds collimation well. Couldn't be happier. I have added some stickers too. Good customer service, I asked if the scope has internal baffles and Testar representative personally checked and confirmed for me! Fast shipping too (I am in Brisbane)
