He was, of GVA Klönsnackabend with an exciting topic that was Eric-Sven Vesting of astro-shop presented insightful and knowledgeable. Many times I had as such a "eureka moment" and to me it was quite clear. About that one - in my view - the conversion of the cameras should be better left to the professionals, and that there are many ways to turn a standard camera is suitable for astrophotography. It is also recommended for this purpose the selected recording device used exclusively for astrophotography. There are several options (white balance) to use the camera in normal everyday life, I would not want to do.
That the conversion currently works only with Canon cameras is (in the U.S., surprisingly, is considered a particularly cheap brand), is mainly due to the hurdles in the software of other camera makers, technical conditions, etc. It are also a number of nuisances, such as different filter thicknesses that the conversion - into a laborious affair - even with Canon. Also the support of the companies is very different, especially when it comes to technical details of the cameras and the built-in components to them.
A wide field, the relevant modifications to Astro, full-spectrum and "Only-IR cameras, which one makes for the purpose to increase the H-alpha and the general sensitivity of the camera . Some image examples illustrated the effect of a normal camera for astro photography: Normal images showed little, converted a lot more details in galaxies and hydrogen areas. A conversion that is worth it.
The number of variations on the tags surprised me very much and There are naturally some here that do not work for astrophotography or simply ineffective. There are also differences between old and new cameras of the model years 2003 - 2006 and 2006 - 2010, these have been worked out clearly.
Moreover, there was also plenty of tips on how to perform even such a conversion can and what risks are concealed. For me, that, frankly, would be nothing.
I can not reflect everything that was offered in the very educational event of information. Finally, there was a small round of questions and you could still see a disassembled camera, which was also very impressive.
Conclusion: tags, straight from cameras that have been purchased, used and from where you do not know if they have already been rebuilt (perhaps to a full range of camera), are a sensitive issue and they should be the people left who really like this idea and know what they are doing, as the lecturer.
Afterwards we went over to the Knips small Flottbek at the station, so that the evening in the cozy, exciting round was ending and longer than planned.
