My other part of the question is where do you find the actual names of a feature such as AR1972?
The naming comes from the NOAA, you can get it real time from places like SolarHam & GONG links.

Today's Solar Features in High Res | HA, GBand, CaK | June 4th 2019

Heya, I wasn't planning on getting up this morning, was up late doing DSO, but figured I'd take a shot at it and to my surprise the seeing was rather excellent. I already had my C8 on the mount, so straight into fine imaging scale I went at 0.29"/pixel in HA & 0.20"/pixel in Gband and managed to get...

Proms & Filaments near Region of Activity | HA | June 3rd 2019

Heya, Was all doom and gloom this morning, but managed to attempt some this afternoon in the heat that Florida is right now, spiking 100F each afternoon. Ugh! Anyhow, the region with some activity is pretty extended and is churning out filaments so it's fairly active, be it new or a remnent of a pre...

Hi Jack, It really comes down to seeing, sampling and processing. No magic. This tutorial is a little dated at this point, as I do it differently these days, but it will at least still cover a lot of the basics of setup, acquisition, stacking and some niche processing (forgive me its inverted, not e...

Big Prom & Region with Activity | HA | June 2nd 2019

Heya, Terrible weather lately, have't been able to do much and missed a lot of the big prominence the past few days. It still persists but it's a little less grand. There are some large feint ones around the limb, but weather didn't allow me to capture them. I did get some data on the little region ...

Re: Plage, Prom, Discs | HA, GB, CAK | May 26th 2019

Hi Eric, In FireCapture with a Flat Calibration frame and Gamma checked and being used, it is around 75fps at full resolution. It's much faster if I turn off the flat calibration & gamma use. I have never been able to get the full advertised fps from my IMX174 nor the 290MM with my setup. I'm using ...

Re: Improving 1 angstrom Stage 1 to .5 angstrom

Hi Jack, The bandpass isn't what's important. 0.5A or 0.7A or even 1.0A compared to 0.3A isn't important really. More important is the transmission profile and the skirt around the wavelength. My Quark operates around 0.4A and my PST is 1A like most others. However, the reason I use the PST etalon i...

Re: Plage, Prom, Discs | HA, GB, CAK | May 26th 2019

Hi Maurits, yessir, all where done with the ASI290MM except for the Plage in HA, that was the 174MM. The rest, convection cells, discs, etc, were with the 290MM. I've been experimenting with using the smaller sensor to have more options for image scale using smaller pixels.

Heya, Had some ok seeing this morning and was able to tinker around in various wavelengths to test things out. The little plage is still present near the limb, but it's activity seems to have already gone down a bit and the large proms from yesterday are gone, but a small bright prom is on the other...

Re: Improving 1 angstrom Stage 1 to .5 angstrom

Double stacking it is the only way to narrow it down to 0.5A.

Heya, Low activity, but a little more than the past few days at least. There's a little plage that formed the other day and is still persistent with some tiny filaments around it and spicule bundles here and there. Some fair prominences are near by on the limb that have lasted the night so far. Seei...

Re: DIY Solar Wedge ND3.0 alternatives for Imaging only

Heya, All good, you mentioned this is for imaging only right? A UV/IR block filter and a KG3 with any sort of colored dielectrically coated imaging filter would effectively mitigate any serious heat issues and allow upwards of a 150mm refractor's aperture without any problems with the camera sensor....

Weird tendril-like features in chromosphere? Identification help?

Hey all, Bald disc today, not even a prom! But, there's always something to see in hydrogen alpha. I'm curious what these strange tendril like structures are in the chromosphere. I find them sometimes and they are very short lived and move along. Makes me think they are related to spicules with how ...

Re: DIY Solar Wedge ND3.0 alternatives for Imaging only

Heya, Is this strictly for refractors? What aperture range do you want to have on it? You really do not have to make a Herschel wedge for imaging only. Wedges kill transmission, which is ideal for visual use, but for imaging, you don't have to do that. You just have to have transmission low enough t...
