Am not much into the photography side. First pic (moon) was taken unguided same day as the first pic setup in the original post, second one (sun) unguided with some additional HA filters with someone else, and third one (horsehead) is a ~160 minute exposure taken as part of a group including pro Apo equipment, real experts and autoguiding, in the Himalayas.

Here are others' pics taken using the same C6 SCT scope: https://www.astrobin.com/search/?q=Celestron+C6+SCT

If those pics are underwhelming that's just a reflection of my undeveloped astrophotography skills. I enjoy more the serene visual side of astronomy, and my most-used equipment is Oberwerk 11x70 big binoculars.

AP has a steep learning curve. It takes around 4-6 years to master. Just setting up the scope in polar alignment (with the axis pointing at the pole star to match the earth's rotation) takes 10 minutes for a visual session and 20 to 30 minutes for sufficient accuracy for AP.

Consider the third pic, it's not a wide shot of the milky way, it's 20 shots of 480 seconds each, equivalent to a 160-minute long exposure of a deep sky nebula called the Horsehead nebula in Orion; matching its movement at a pixel level for that long with 3-4 kgs of moving gear is a technical challenge. Vibrations of people walking on the floor, heat rising from concrete, backlash in mechanical gearing etc all affect the image. Imaged through an apochromat, around three scopes are typically used together on a mount and a computer uses information from a second scope and small cam (autoguider) to correct the first scope with the larger DSLR or CCD imager. That third pic is beyond my personal solo technical ability.

(The Horsehead nebula is close to the lowest star in Orion's belt in the pic below. This image is approximately what's visible from a city, IIRC I took this with a 50mm f1.2 lens on a DSLR)

The mysteries of the Cosmos would never be understood by morons like you.
Least you can do is Apologize & Delete your infantile comment. :mad:
All items above are world class.
Rare to find such lay astronomers in India who would possess gear such as this (which otherwise is quite common in the US).

Wishing you the Best @salian for this sale.
Keep gazing at the skies and into the realm of universes & stars billions of miles away.

It's a masterpiece - the Horsehead Nebula in Orion
WOW & the science, skills needed to master capturing it using portable scopes.

I am attracted to Cosmos most of the time and while I did this I began to go to NASA, Seti, NOAA etc organisations and learnt a lot. I mean this Universe is immense right and it has many creations like us as we are not the only Crown Creation of God with big G. Yes I believe in Aliens and UFOs... because I have seen not 1 but in 3 instances of Unidentified objects in the night sky during 2016-2018 and they are absolutely wonderous and superb.

The western society folks see them everyday because they are exposed to such information beforehand than us but in fact we need to take interest in such topics like common people also.
 
I literally stared this pic for almost 10mins, my mind just got stuck into it.
When I see pic such as this I wonder, is there an end of space? or is there some form of edge? or after certain distance its just empty ? why is everything there ? how these celestial bodies came into existence ? or why do they even exist ?, it's just a never ending train of thoughts!
Sometimes I feel, I wish I could just glide through space into never ending realm of unknown.

I'm an Astronomy-enthusiast...

1) What you have explained in such depth, (to that Xiaomi fone response,) is beyond that reply's league.
Hats off for such detailed explanation.

2) Also, I'd really wish, I had that much, I would sweep it right away!

3) Another 2nd comment, "about joking" = #Kantesh... Is really lame shameful that despite your arrogance & disrespect you're still existing in TechEnclave Forum!


I'd like to know if you're a solo observer or are in any clubs/groups?

Regards,
FreakyChokra.

Thank you @salian for all the amazing insights that you have provided on this thread for a lay-person to pursue *Astronomy* & discover the wonders of our Cosmos.
I was interested in this subject ever since 1978 when I first visited the Nehru Planetarium at Worli, Mumbai and subsequently over the years. I had always wanted to have my own Telescope & even in the 1980's there were options for DIY Telescope Kits .... Although I would have preferred a Celestron anyday - for it's compactness. My Only reason for not moving ahead was that - I live in Mumbai (where Telescoping on any given day - and even during April-May Summer months - the Night Sky is So Bright (owing to the city lights). And I did not have a vehicle or means to carry that gear to remote locations.... and so I gave up. But again Kudos to you. It would help if you can list a couple of *Amateur Astronomer Groups in India* here on TE city/region-wise - who frequently meet with their gear to STAR GAZE. The Gear that you have is all PREMIUM value - However, here on TE -the above may help too for any interested person.
 
Near Mumbai the basic scene is good in Vangani, Mahuli etc. In the mid-range some of my college seniors run Starscapes which also has tieups with Club Mahindra etc. And for god-level stuff Ajay Talwar sir runs annual workshops in dark sky locations. I also try to take holidays in places with dark winter skies. MTDCs are good for spacious and safe environs.

But this is all few times a year type of stuff. Nothing beats whatever you can do at home without a lot of prep - the best gear is the one which you can use regularly. There are so many accomplished individuals in India these days observing from their terraces in smaller cities.

I don't have a balcony or terrace now, nor a view of the pole star. So @jmaniac moving to a lighter setup which is more travel friendly and fits in a backpack.

... 3 instances of Unidentified objects in the night sky ...

I saw UFOs once in 1996 through a Tejraj scope from my parents' home terrace and it was an exhilarating moment. Eventually they turned out to be high altitude migratory birds. (The UFOs, not my parents). Thank goodness they were flying towards my location and the mystery was resolved, else I would have spent my life wondering if the truth was out there.

I worked at Arecibo Observatory for 6 months. Although it was a radio telescope so it was mostly data but no beautiful pictures. It was still such a tremendous experience. I still sometimes try to do my best to take some photos when I get a chance.

Here are some.

WOW at Arecibo
