Sun in H-Beta

The Sun imaged in H-beta using my Sol'Ex and new ASI678MM camera.

Jupiter - One week before Opposition

First time this year that I captured Jupiter. Temperature was 1°C and declining.

Setting:

TAL 200K @ f/23 with Barlowx2, ADC and IR/UV cut

ASI224MC camera

Software : SharpCap, AstroSurface and CS4

Sol'Ex with new ASI678MM

My last observation of the Sun dated from September 21. Today I had a day off and luckely with some good weather and a lot of sun. Unfortunatenly some high clouds made it unpossible to image the sun in the afternoon. 

Sunshine on this Black Friday November 29, 2024

To image the Sun I used my classic set up with TS TLAPO60/360 with Sol'Ex Pro and my new ASI678MM camera. This camera has 2micron pixels, much smaller then my 2,9 micron pixel 290MM camera. Both telescope and Sol'Ex are mounted on my EQ8R.

Imaging was done in H-alpha and H-beta and all H-alpha data was also send to Bass2000 as part of the Solap (ProAM) program .

Reworking 2017 Eclipse pictures using Larson-Sekanina

After attending the The Dark Day (DDD see https://pascalhilkensastropage.blogspot.com/2024/11/dr-sebastian-voltmer.html) I searched my 2017 Solar Eclipse images.

I found two sets: 1/15s and 1/50s. Each set was stacked and then treated with special Larson-Sekanina filter (low radius, low rotation) in Fitswork 4. The stacked image and the LS filter image are substracted; The results of the two sets are then stacked and edited. The final image shows the low and high corona.

During the DDD (De Duistere Dag - The Dark Day) on Saterday November 16, 2024 a lecture was given by Dr. Sebastian Voltmer. Voltmer is beside a movie director, composer also an astrophotograph.

During his lecture he showed many images including eclipse pictures from Mexico (April 8, 2024).

Some tips he gave:

• use of bracketing
• use two camera's for eclipse photography; one 135mm, the other 700mm in order to image the entire corona
• sort eclipse images by exposure time, stack and edit the result using Larsen-Sekanina filter Fitswork
• Finaly stack all edited images to one image; this image can be edited aswell

New Weatherstation Levenhuk PRO LP500

I replaced my Oregon WMR200 and BAR928 with a new weatherstation Levenhuk Pro LP500. Both Oregon stations are >10 years old and the sensors did not work anymore. My preference for Levenhuk Pro LP500 was based on following criteria:

• Measuring in/outdoor temperature, humidity, rain, winddirection, windspeed and pressure
• Data capturing of all data in order to do analysis
• Samrtphone connection 

The Pro LP500 forfills all criteria and has following extra's:

• moon phases
• sunrise, sunset and sunpath
• UV index
• Solar radiation (Lux/W/m2)
• automatic time
• link to Ecowitt and WUnderground and thus linked to smartphone
• datacapturing via microSD or direct PC connection
• weather forecast

Using PWS Monitor app, you can find my weatherstation with ID = ISCHER75
