Night photography help

[iamsomnath]

This belongs to the Jokes thread

No Yaar seriously. Actually when I started doing photography due to high cost of films we barely had the budget to do any experiment ( one blessing I count in favour of digital imagery ). But I see a lot of very fine experiments all around and somehow that has motivated me to try a bit. Let's see how it pans out. Wish me luck

Cheers

Very lucid and comprehensive discussion by Ankur and Arshad bros. I am a novice when it comes to shooting the night sky. Hope to try my hand in near future

ha ha ha. Arshad bhai, looks like Somnath Da didnt get any bakra from morning...

The Day Somnath da tries this
I am gonna be like

@Roadie.. you have finished my astrophotography even before it started

@Roadie.. you have finished my astrophotography even before it started

Haha who am I to finish that..
Its just the confidence that we know you will excel once you venture into it

Just kidding. I hope the OP doesn't mind the long chain of our enlightening OT conversation that we have had ...LOL . Ciao

Ankur the 28 sec i.e. 500/18 is for full frame
We get 500/27 aprox 18-19 seconds in crop sensor

Arshad bhai, I am not sure if I agree to what you said. I have searched numerous threads on web that confirm your claim though.
According to my understanding, angular movement of star is same no matter what is the sensor size (pixel density being same)
A crop sensor camera is showing you a smaller portion of the image of what would be captured by full frame sensor, so technically angular movement of stars should be same for both formats.
hence no need to use the "crop ratio" in "rule of 500"

True Angular movement remains the same
But the crop sensor magnifies the movement by 1.5 times for APS-C.

You see there is star movement even for a 5 second exposure
Its just that we cant notice it.

If I try 25 seconds on APS C it clearly shows movement
While 18 seconds shows none
