About CHOICE CCD2 Class 2019

This topic is for people considering joining the CCD2 class this year.   Here you can ask the instructor any questions you may have before signing up.  I've attached the Syllabus from the 2018 course.  The course changes slightly each year as new discussion topics may be opened based on comments or questions from the students.

Not shown in this syllabus are the observing project comments and instructions, and the VPhot discussions for students learning VPhot during the course.

CCD Part 2 Class

Hi Phil

I was thinking of signing up for this. Just a couple of comments / questions:

1.  I have a working scope (a Celestron Edge HD 8-inch) with UBVRI filters and a CMOS camera (a ZWO ASI 1600 MM Pro), but am not confident (given the weather here) that I will be able to capture appropriate images during the course itself. Therefore, I would be likely to want to use "images provided by the instructor" as per the course description.

2.  I also note that CMOS cameras are not considered suitable for CCD Parts 1 and 2. This, however is not a problem, if there are instructor-supplied images.

Hi Paul,

CMOS:  People in the AAVSO is still trying to figure out the best ways to use CMOS camera's for photometry, but results are yet to come in.  Most CMOS cameras have very small pixels, lower digitization (12 bit vs 16 bit), and smaller Full Well Depth,  when compared with CCD cameras.  I expect there may be a separate CMOS photometry course and CMOS photometry guide documant when this is all worked out.

You would get the most from the course if you made your own images for the observing project, but images can be provided if you are otherwise prepared for CCD2.  Have you done much imaging with a CCD camera or your CMOS camera?

There may be two sources of "instructor provided" images for the course observing project.  I'll be observing the project field with my own scope and STL1001e camera.  I'll make some of these images available to the students, but I may have the same problem as you.  The climate here can be very cloudy in March and into April.  I'm also hoping to get images from one of the larger AAVSO Bright Star Monitor network scopes that can be used in the course.
