Himanshu Rastogi, Amateur Astronomer

I had attended the Sky Photo Trip in Sept 2010, when it was conducted for the first time. While the weather conditions weren’t very favourable at that time, but the image processing and equipment handling sessions with Ajay Talwar were incredible. There was a lot to learn from those sessions.

Kiran Mehta - Ethos of Aperture Telescopes

I’m impressed at the unique ethos I sense about Aperture Telescopes, that of complementing a ‘do-it-yourself’ culture, rather than replacing it only for commercial gain!

Fantastic!!

Vikrant Narang, Scientific Officer, SPACE

Sky Photo Trip was an excellent endevour to set the bar very high for Indian astrophotographers and go beyond the basics of astrophotography. There is simply a LOT that goes behind taking inspiring and world class astrophotos – from meticulous detailing, extensive instrumentation and procedures, hours of post processing, to decades of experience – Ajay Talwar shared everything unreservedly and enthusiastically with all the participants. It was a great opportunity to be at a scenic dark sky location, with tons of high quality equipment and expert guidance. It was great to be with passionate bunch of people from all over India (and one of them all the way from Duabi)

Vishnu Rethinam, Amateur Astronomer

Messier Marathon 2010. Saturday, 13th March 2010 the Messier Marathon at Majhkhali was conducted using the 20 inch Aperture Telescope. While pointing above 45° the huge telescope requires a ladder, but that is no deterrant for finding the messier objects using the Telrad finder. In fact finding objects is simple and intutive, finishing the Messier Marathon is a breeze. The motion of the telescope is smooth, following a messier object as it moves in the sky is very easy even from the top of the ladder. Vishnu Rethinam, a long time Messier Marathon runner used the 20 inch Aperture Telescope exclusively to run the marathon this year.

I’m discovering astronomy in my 60s thanks to Ajay & Aperture Telescope. I thought my daughter was absolutely crazy when she told me, “Let’s go see all the planets in Manesar. A very nice gentleman is organising an event.”I went for the planet alignment and got to see Jupiter, Saturn, Mars and Neptune. I got too tired to wait up for Venus & Uranus. It was a mind blowing experience! Ajay is such a great guy!! He explained everything so well, and I really enjoyed his jokes too. I thought my daughter & I would be the only ones there, but boy oh boy! There were at least 30 people there at 3am. I can’t wait for July 13 super moon

Thank You Aperture Telescopes & Mr Talwar!! My mom and I went at 2:30am for the “planet parade” when all of them were in a straight line. BEST DECISION I TAKEN THIS YEAR!! I am so so so hooked and can’t wait to learn more. Last night was the first time I ever saw any planet from a telescope. Mr Talwar taught me so much and he has so much personality! I can’t wait to go back to learn more from him.

I had a brilliant experience with aperture telescopes. Had a wonderful experience seeing Jupiter, Saturn, Moon, Venus, Binary stars through the 20 inch Dobsonian at the workshop. Mr Ajay Talwar guided me perfectly on how to use the telescope and I also bought a telescope which is really efficient.

I attended several Sky Photo Trip astronomy workshops conducted by Ajay Talwar, where the seed of astronomy was planted in me. I then decided to setup my own backyard Observatory at The Homestead near Ramnagar, a project which I couldn’t dream of undertaking if I didn’t have the support and backing of Ajay. Now my dream project has come true with a 8” Celestron CPC800, a 14” Celestron CGX-L Telescope and a 12” Dobsonian made by Aperture Telescopes. All this is thanks to Ajay and I also feel so proud to be rubbing shoulders with a world renowned astronomer such as him. Thanks Ajay for being my Guru.

An Aperture Telescopes' Mirror for IIT Delhi
An Aperture Telescopes’ Mirror for IIT Delhi

We are quite thrilled to make an 8-inch mirror for Indian Institute of Delhi. Quite surprisingly the purpose of this mirror is not at all for a telescope, but it will be used for Schlieren Imaging System.

YEH JAWANI YEH DIWANI POINT

There is a beautiful grassy expanse just about 500 metres eastwards and about 100 metres higher elevation from the road head of Jalori Pass. It takes about 15-20 minutes to climb up to this fantastic panoramic vantage point. You can see the Pir Panjal, Dhauladhar as well as the Shivalik from this location.
