Re: Issues with COAST

Ed, your flat was available now and tonight's images looked improved compared to before. Thanks.
Bob, I have not analyzed my images as carfully as you have but I think your conclusions seems right.

Re: Issues with COAST

Thanks for your response Ross. On the old BRT telescope I also used a synthetic flat that I made in IRIS. I have not experienced that the vignetting on COAST is that severe that I have needed to use a home-made flat, it usually is enough to remove one or two comparison stars. It may seem like a luxu...

Re: Issues with COAST

What I understand there is no flats applied to the images from COAST. It is visibly at current with the strong moon shine that the images suffer from vignetting. It is also visible in the photometry where I have to avoid comparison stars at the edges of the images because they deviate to much from c...

Problem with focusing

First, I think COAST have been a huge sucess the last months. It had produced images almost every night in a huge quantity and I have got lots of images of variable stars to work with and great light curves. But I have noticed that the stars on the images have been out of focus the last nights. Have...

Weather data/web cams

Hi. Will the COAST telescope have weather data and web cams to show on the web site as BRT had before? Or will the weather station and the web cams on ART/BRT become online again? I think this was a nice feature to see all the different weather stastistics and how the telescope and surroundings look...

Re: No observations again

Thanks Ed for informing us. You have allways been very helpful and trying to answer our questions and making very nice applications for the BRT web. I can't belive that BRT will get a such stupid ending. It is a world unique facility for amatuer astronomy around the world.

Re: Equitable use of the BRT?

I think this will be hard to implement. What will decide if an request is for a dynamic or static object? An other approach is to give every user a certain amount of telescope time insteed of a certain number of requests. If you have, for example, 18 minutes you could choose to request two 3 minute ...

Re: Community research publications

Here is another article where BRT has contributed with several observations. In fact was the initial discovery that V2331 Cyg is an ecplising variable made of images from BRT. V2331 Cygni is an Algol Variable With Deep Eclipses (JAVSO, 2013, vol 41, page 264) http://www.aavso.org/media/jaavso/2934.pdf

Re: Number-of-Requests Scoring Module

I think the suggestions from gasparovic and rjmodic are all great and should be seriously considered to be implented. I think that all of these features could be of use for my work with variable stars with BRT.
