Atik Titan – Gain and Read Noise Analysis

This is an analysis of gain and read noise of the CCD Atik Titan.
I used as samples, two bias frame and two photos of M27 taken with 60 seconds of exposure, even though it should be done with flat frames, as said in my documentation, probably because they have a better signal to noise ratio.

Anyway the result are in line with the official website specification so I am more than satisfied.

Here you can download the sample images I used.

	STD	Mean Pixel		Atik Titan Specification
Bias1	21,04	1235,00
Bias2	20,95	1235,00		FWC (e-)	22500,00
Flat1	468,87	11883,83		ADC (bit)	16,00
Flat2	492,62	11798,47		Readout Noise (e-)	7,00
				FWC (e-/ADU)	2,91
Mean (Bias1 + Bias2)	2470,00
Mean (Flat1 + Flat2)	23682,30

STD (flat1 – flat2)	419,72
STD (bias1 – bias2)	29,51

Gain (ADU)	0,12
Gain (e-/ADU)	0,35			Gain Factor (e-/ADU)	0,34
Read Noise	2,53			Readout Noise (ADU)	2,40

Testing AIRY ED90 with Atik Titan and QHY5L-II

Testing payload and focus with my two cameras Atik Titan and QHY5L-II on AIRY ED90 with the following components:

With AIRY ED90 – Refractor 90mm Aperture – 500mm Focal length

Sadly looks like the diagonal is required in order to use CCD cameras and eyepieces with this telescope.

Atik Titan with Diagonal and no filters ( Focal length 495mm )

Atik Titan with Diagonal + Barlow 2x ( Focal length ~1000mm )

Atik Titan with Diagonal + Eyepiece ProZoom 24mm ( Focal length ~1200mm )

Without saying that this configuration is really heavy, way too long and can’t balance the mount in dec…

Atik Titan with Diagonal + Eyepiece 20mm ( Focal length ~1500mm )

Atik Titan with Diagonal + Eyepiece 16mm ( Focal length ~2000mm )

QHY5L-II with Diagonal and no filters ( Focal length 495mm )
