    Robin,

    This was just a 300 s raw exposure uncalibrated, no dark or flat frames just to check if the h alpha line has changed.

    Robin,

    The response I am waiting for is if you are able to do a comparison between the spectra obtained by Marc and my spectra, as taken with Marcs C11 and my C14.

    Please refer to Marcs previous post for info.

    Andy,

    You mean like this, the latest ‘quick’ spectrum of vv cep taken around 22.00 hr 2017-08-10 revealing no changes in the h alpha profile yet.

    Andy,

    In our last communication I measured the resolution and inserted it the fits file.

    I have posted a png file of my latest ‘quick’ spectrum of the h alpha profile of vv cep.

    Marc,

    I am awaiting Robins response on this one.

    Also, just a minor point to resolve before I can upload spectra to the database.

    Marc,

    I can send data to Robin for analysis who can post comparative results on this forum for the benefit of all.

    Robin,

    I am keen to submit my data for further analysis as suggested by Marc, BUT I use BASS not ISIS to do my data reduction.

    Thank you for your input, any further comments welcome.

    Marc,

    I use Shelyak SE0002B Lhires III 4 position slit NOT the photometric slit as advised by Olivier Thizzy sometime ago.

    Hello all,

    I would attach a calibration lamp spectrum.

    But bigger than 2 MB is there any way round this ?

    Marc,

    Perhaps the difference between our spectra is due to the fact that you use Angstrom units and I use nanometers so a factor of 10 out.

    Ernst take note but I am sure you account for this when combining our results.

    Marc,

    I am using a 23 micron slit as opposed to 35 micron.

    So would the difference in slit width account for changes in the baseline ?

    The weather here in the UK is not good.

    Still no change in the V H alpha emission line.
