[BAA Comets] Some questions on working towards ICQ report

[Tony Angel]

Hi,

I have just about worked through Roger's Tutorials - I have done everything upto but not including COBS, but before I can produce an ICQ Report I have a few outstanding problems.

1. Tail length. What do you do when the tail goes off the edge of the image. Sometimes I cannot image with the C14 F11 and the 4" F4 during the same run.
2. In FoCAs I cannot get the E-mail setup to work - anyone using hotmail with FoCAs? (not a show stopper)
3. Coma diameter and Tail length. Do I base this on stacked or single image? Logic tells me to use stacked because a short image may not collect enough information. For example this morning's C/2014 E2 stacked shows a coma of some 12 arc minutes, but a single image about 3.75 arc minutes.
4. COBS Registration
    a) ICQ code: is this the same at the MPC code or is it something else I need to apply for soon? (Yes I know that I can put ANGxx in that field)
    b) What is observation method - is it "C" for me, or it something else because I am using an SBIG CCD which is in the red?
    c)  Default reference star catalogue - do I put down the one I use for astrometry or the one I use for photometry?

Once I get into COBS I might have a few more question LOL

Finally, what is meant by an observation from the Section point of view?    

Thank you in advance. : )
