I am wanting a new camera, NOT DSLR.

Post by skyhawk »

Simple question or not

I am wanting a new camera, NOT DSLR.

1. Why when large sensors are now available in cameras for £500 at 12+MP are there still 2MP cameras available costing more, what is the point of a small MP camera when 12mp + are available

Wanted for imaging Moon, Sun (PST)

Thank you

A photographer friend said that the more pixels that there are and the greater the "noise".
I have a 8 mp LUMIX compact with Lieca optics and Panasonic electronics, costing £250.
With the compact, I was able to take a good PST image of the Mercury transit, showing the planet not much bigger than a full stop, the solar disc streaked with dark filaments and two small prominences. The camera was hand-held at the eyepiece, so I had to make several attempts because of the shakes to get a sharp image.

Market forces.

DSLRs etc. are sold in large numbers to the general public, so the price comes down.

Specialised astro cameras are sold in small numbers, so unit cost is higher.

The quantam efficiency of astro cameras also used to be higher, but I don't know if this still the case.

It has little to do with pixel numbers.

David
