Finally the UPS delivery tracker shows that the camera is on its way, currently in Germany after being transferred from JTW Astronomy’s Netherlands location.
The tracker states that it should arrive by this Thursday evening. Hard to believe, I’m hoping it arrives by Friday, as I should be home most of the day. Just in time for our Astro Club’s next big meet up in the country, on Saturday! And amazingly, the weather looks spectacularly good on that night, the first decent one for many weeks. What a pain it’s been.
I’ve just downloaded the camera manual here, need to read up on the basics, including ISO, bulb and RAW settings.
Now I’m planning the first-light test of the camera. I’m thinking of the following:
- Single shot tests, all starting at ISO3200. Series of 30 sec, 1min, 2 and 3 min single shots
- Repeat at ISO 6400 and 12800, reducing exposure time as needed! Why only 3 mins maximum? Well at this ISO, it’ll be equivalent of an 18 minute shot on my 40D.
- I will take equivalent darks and note the outside temp approximately. All shots to be REAL astro pics, connected to my E-130D scope, guided.
- Flats will also be taken, to assess the likely vignetting with such a large sensor.
- Then a real-life astro scenario, a series of 60 shots taken at 1.5 mins, 3200 ISO, full set of darks and flats. At 3200, 1.5 mins is the equivalent of 9 mins on my Canon 40D. Depending on the results of the individual tests, I may increase or decrease the exposure time to be applied.
- Since I just took a picture of the Horsehead nebula, that should be an excellent comparison target to work with.
Feel free to suggest any other tests you might like to see. Wish me luck with:
(a) the delivery of the thing; and
(b) the weather!
