Hello,
T CrB seems to be a relaxed season despite little variations in its Hydrogen lines.
Photometry is moving too, the empty is due to bad weather.
Cheers, J. Guarro.

Re: T CrB before its new nova event
Hello, Unfortunately, bad weather persists here for a lot of weeks, and the forecasts can't say how many times it will last. Meanwhile, I attached here this graphic where I gathered these four photometric observations, you can see a change in magnitude tendency that is difficult to notice to see th...

Re: T CrB before its new nova event
Hello, I've attached two graphics today, in the first one you can notice the notable difference between T CrB H Alpha activity on 2022 08 18 and the current little oscillations on its weak signal nowadays. In the second picture, there are only 10 photometric points taken in not more good conditions....

Re: SMM's 16-inch MEADE LX200GPS TELESCOPE PROBLEMS
Hello, I attached here a photo that shows part of the job that Toni and I did to update the Meade 1209 focuser to join one stepper motor that OnStep requires. At the same time, we prolonged the draw tube travel by 2.5mm., so it's 14.5mm. now. After a lot of hours of work, we tested it with no better...

Re: T CrB before its new nova event
Hello,
You can see here T CrB on 2024 04 23, its general situation is calmed, although its photometry shows little variations.
Cheers, J.Guarro.

Re: T CrB before its new nova event
Hello,
These are yesterday night's T CrB outcomes, its spectroscopy graphic, is only by 4 x1800 seconds integrations, due to the night becoming cloudy, despite it, the photometric measures have one reasonably good dispersion of +/- 4 thousandths of V magnitude.
Best regards, J.Guarro.

Hi again,
As a curiosity, I used these stars as a V photometric comparison.

Re: T CrB before its new nova event
Hello at all, The T CrB outburst current year predictions has grown the interest for this star, as the same that the observers who targeted it I found T CrB in a really normal state until now. Also you can see in its spectrum how the ASI294MM works, the graphic is the result of 6 x 1800 seconds inte...

Re: NEW NOU_T ECHELLE RESULTS
Hello again, Finally, the weather improved, but without good seeing, I could observe with the Piera equipment, this time the target had V694 Mon. You can see the outcome here and the low or inexistent amp-glow effect on the final image and its graphics. In my opinion, for the NOU_T echelle, these re...

Re: NEW NOU_T ECHELLE RESULTS
Hello at all, Meanwhile, Toni a I were occupied trying to install the OnStep system, the ASI2600MM camera of the Piera Remote Observatory equipment, was a leak of internal cooling liquid over its CMOS, which is one common damage that can happen in the first building series of this camera, ZWO knows ...
