DMK 41 vs Point Grey Grasshopper in solar astrophotography

2010-08-09 11:51:14.717917

Rolf Geissinger compared DMK41 with PRG Grasshopper GRAS-14S5M-C for his solar astrophotography. As you can see on the images he provided - Grasshoper provided better results. The increase in sensitivity is clearly visible. The PRG camera is equiped with ICX285 - a CCD known from DS cameras (DSI III, Atik 314L) and also it uses new Firewire 800 interface which allows it to send up to 15 full frames per second. You can also look at Rolf other solar images made with this camera.

QHY reveals list of their planetary cameras

2010-08-09 11:47:24.882439

QHY revealed full list of their planetary cameras (multipurpose cameras). They should be available for order next month. We get 14 bit A/D, optional TEC cooling, and new and sensitive CCDs compare to for example The Imaging Source cameras. QHY IMG0H and IMG2S looks like the hottest ones (QE of both is above 60%).

QHY IMG0H	ICX618 Exview CCD	1/4" 640*480
QHY IMG2S	ICX285 Exview CCD	2/3" 1360*1024
QHY IMG0S	ICX204	1/3" 1024*768
QHY IMG1S	ICX267	1/2" 1360*1024
QHY IMG0X	ICX424	1/3" 640*480

Then it must be some int to string checks somewhere which make the captcha fail.

I've made any tests in my system.

1. I've registered several accounts when the captcha is built with letters. And it works.

2. It fails if is built with numbers. In fact, when I registered myself in this forum I was failed in the first time --it was a number capcha--.

Tryton - business application collection and framework

2010-06-01 00:54:19.227237

Tryton is a business GUI application framework and a set of applications of that type. It supports invoicing, tasks, calendar and much more. This framework works in a client-server manner and uses PostgreSQL database, PyGTK+ GUI toolkit and is available for main operating systems (the client part).

I've installed pre-made packages from Linux Mint / Ubuntu repository and used one of Tryton test servers to test the client application:

The application runs fine, not problems with stability. In Tryton there are many finished applications that can be used:

I can't rate how much functionality they provide, but they do look interesting. And it's Open Source software.
