Supernova SN2026sqf in NGC3310

A type II supernova (a core collapse supernova) named SN2026sqf located in NGC3310 (UMa) was imaged using my TAL200K f/8.5. NGC3310 is about 50million ly away.

Setting: TAL200K f/8.5 with ASI2600MC

Filter: Optolong L-Pro

Total Integration time : 10*300s or 50minutes

Use of bias, darks and flats (for the first time using my flatscreen at night and thus have all data right after my imaging session).

Software : SharpCap, ASIAIR, APP, DeNoise AI, ASTAP, CS4.

Sun in H-beta

 

Sun on July 25th imaged in H-beta using my Sol'Ex by James R.

Sun with Nikon D7500

Still a couple of weeks to go for the total solar eclipse in Spain. Thus... need to exercise with my Nikon D7500.

Calcium lines contrast enhanced using AstroSurface

I reworked a couple of my CaIIH/K images with the objective to increase the contrast. I was able to do this using AstroSurf. 

Workproces

- Inti processing of CaII Ser files

- DeNoise AI to remove noise 

- Astrosurface : wavelets, mostly high frequency and Local contrast enhancement

- CS4 : unsharpen mask, noise reduction (what's left) and false coloring and adjusting brighness.

These are the results; I may conclude that difference between first two (July 25) and third picture (July 4th) is due to active versus quiet Sun. 

Sun on July 25 - HeID3 using FeI

 

Imaging the Sun on July 25the in good conditions. Seeing about 1arcs average, measured using SSM3. Tilt is back in basic condition and below 0,2°.

HeID3 imaged was processed with Inti and started from the FeI line instead of NaID2 line. By doing this a smaller ROI could be used. Scanspeed remained at 16x resulting in a sx/sy of 1,8. To improve I will reduce the speed next time. The HeID line is about -142 pixels away from the FeI line, compared with the NaD2 line which was about -250 pixels. Winning more then 100pixels on data. 

The solar tornado is visible in all lines except MgIB2.

MgIB2 shows finer and sharper details in the active sun which are more blurred in H-alpha, HeID3 and both calcium ion lines. 

Calcium images are processed using Inti and edited with DeNoise AI and AstroSurface: wavelets, local contrast. This way it brings more structure, typically supergranulation. 

Solar Tornado

During my morning imaging session with my Sol'Ex spectroheliograph, I captured a striking "solar tornado" anchored along the western solar limb. Driven by complex magnetic flux ropes suspending plasma in the corona, these colossal structures only mimic terrestrial whirlwinds in visual projection. This observation highlights the remarkable ability of modern amateur spectroheliography to capture dynamic solar physics in real time.
