I haven’t been into the Astro-imaging “business” for quite a while, so I thought that this situation must change 🙂

Luckily, there were a few occasions in the last few days to get some images, like three ISS  transits and some solar prominences. Also some lunar shots, but for those I’ll have a different post.

I’ll start with the Sun:

-Two rather large proms on the Sun, images in H-alpha with a 115mm refractor and Quark Chromosphere filter. Poor to fair seeing for this shot, and the proms were pretty faint, but this is my first H-alpha shot in a very long time…

-An ISS solar transit, imaged in poor seeing, with a 115mm refractor in Green light. Note the inset showing a better view of the Station, the image itself being a stack of multiple frames.

-Yet another ISS solar transit. Again imaged with the 115mm refractor but this time using for sensor the Canon 6D at ISO 100 and 1/4000s. A 0.7 second event captured in an agricultural field near Comana, GR, at 36 Celsius.

Another ISS transit from August 6, 2019. This is a short gif showing the ISS at about 1/20 the speed it actually transited the Sun. 115mm refractor and Herschel wedge with ASI 174MM, on a cloudy day…

One very small sunspot group from September 3rd. Imaged under excellent seeing in both H-alpha and White light with the 150mm refractor.

And a 20 minutes animation of the sunspot group:

The Moon under very good seeing conditions, considering the low altitude of only 20 degrees. Imaged with the 115mm APO refractor, ASI174MM and green filter.


The Moon on October 1, 2019. Imaged at only 16 degrees of altitude through some bright and pink skies soon after sunset. 200mm Newton and ASI174MM.

An old film shot of a partial solar eclipse…


A comparison between the ISS and the Aristarchus crater on the Moon. The size of the ISS is apparent of course, but it shows just how large it is compared to lunar features, as viewed from the ground. Both imaged on the same night, minutes apart, as the ISS crossed the sky not far from the Moon. Both at around 40-50 degrees of altitude. Poor to very poor seeing. Imaged with the same equipment (200mm F/5 Newton with 3X barlow lens, ASI174MM, Red filter). The image is a montage, so NO, the ISS did NOT transit the Moon on this occasion ;). December 8, 2019.


And a three frame animation from the above session, showing the ISS in very-very poor conditions. Nevertheless, some structural details may be glimpsed…


Another result from the December 8 session:
