Re: TCP J17562787-1714548
I've been following this nova this week. It rises quite late in the morning so I have limited time to collect data. Its also fading quite rapidly so the SNR is falling away as well. The best quality spectrum I have is for 23 February 2023. I've marked the most prominent lines. Resolution is around 1...

Re: Suspected/Misclassified Symbiotics: spectra required
Another spectrum of V520 Mon - this time in the UV. Taken with UVEX 600 lines/mm grating on a PW CDK 12.5. There is nothing particularly remarkable to see. Balmer and He I absorption lines. The H beta line is in emission and, like the spectrum from 10 December, the line is definitely split. I attach...

Re: Suspected/Misclassified Symbiotics: spectra required
v520mon_20221210_514_Peter Velez.png Another target from the Database - V520 Mon. This is in the visual range - roughly H beta to H alpha - taken with a UVEX 600 lines/mm grating on a CDK 12.5. I only managed 4 x 600s so its a bit noisy. Simbad records a spectra type of O9.5-B0Ve and lists it as an...

Re: Suspected/Misclassified Symbiotics: spectra required
A follow up on Hamish's observation of HD306070. Two spectra from last night - one taken in the UV, the other in the visual spanning H beta to H alpha. Resolution of around 1000 - taken with UVEX using a 600 lines/mm grating through a Planewave CDK 12.5. Happily - all automated while I slept as it w...

Thanks Christophe
it looks like a browser issue. The website works fine in Firefox but not Safari. Looks like I need to change my default browser

Spectro-Starfinder - not working?
Is anyone else having issues with Spectra-Starfinder?
The website has worked extremely well for me up until about a week ago. Now any search results in an error.

Re: UVEX - Shelyak Motor Unit
Hamish Shelyak supply a filter that sits behind the slit for IR and NIR observations. That doesn’t suit me as I want to be able to switch wavelengths without disassembling the instrument. So I have installed a FW between the telescope and UVEX (immediately before the guide unit) with a filter blocki...
