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 | ||

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:
- Diagonale dielettrico XP 90° 31,8mm
- Celestron Lente di Barlow X-Cel 2x 31,8mm
- Oculare Lantanio ProZoom 8-24mm
- Adattatore foto DSLR per Lantanio ProZoom 8-24mm
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 )
QHY5L-II with Diagonal and Barlow 2x ( Focal length ~1000mm )
New Telescope First Moon
One of the first test with my new telescope.

- Mount Skywatcher HEQ5 Pro Synscan
- CCD QHY5L-II Monochrome
- XP 90° 31,8mm dielectric mirror diagonal
This is a mosaic result of a 15 seconds video with an exposition of 0.06 seconds ( ~200 frames ).
Align, stack and elaboration has been made with Registax.

just kidding…
Anyway if you get this compact refractor and you are that type that you like to open everything to understand how it works, be careful when you open the upper part, the lens is kept fixed by the two part connected and as soon as you remove the hood the lens might fall.
