The Omega Nebula (Messier 17) – September 12, 2018

Posted in ASTRO on September 13, 2018 by maxpho

Just a bit of play with this object…Not enough time to get a proper image, and a few issues with passing clouds and with the guiding laptop out in the field, so…not much data acquired. I had to reject 6 frames due to tracking errors or clouds. Still, the general shape of the nebula is seen. Next session will surely be better 🙂

Equipment: TS 115mm F/7 APO, TS FF, Baader 7nm H-alpha filter, ASI 1600MM. Gain 150, Gamma 60. Only 9 exposures of 3 mins each. 1 dark. Guiding with PHD2, a 50mm finderscope and ASI 174MM.




H-alpha Sun – September 9, 2018

Some lovely proms today on the Sun’s limb. It seems that the next few days there will be some activity in H-alpha light.

150mm F/5 refractor, Quark chromospehre, ASI 174MM. Seeing 5/10.

Astro-morning – September 7, 2018

Posted in ASTRO on September 7, 2018 by maxpho

A couple of hours with the morning sky and some nice objects and gathering were observable.

For now, the conjunction of the Beehive with Selene (M 44 star cluster and the Moon, of course).

TS 65Q APO refractor, ASI 1600MM, no filters. 32×1 sec exposure. Different processing for stars and Moon.


Comet 21P Giacobini Zinner, 32 x 25sec frames using the TS 65Q APO and ASI 1600MM camera. No tracking.


And now an interesting observation of a feature illuminated beyond the lunar terminator. In this case it is the western wall of Flamsteed T. Nice bright spot (at longer exposures) looking a bit off-place.


The last of the visited objects from this morning: the Doble-cluster in Perseus.

TS 65Q APO F/6.5, ASI 1600MM, LRGB image (L=80x25s, RGB 30x30sec each). Suburban conditions, some high altitude clouds. Some pinched optics effects detectable due to my recent cleaning and remounting of the rear lens…




H-alpha Sun – September 6, 2018

A solar session, with two fairly large proms dancing on the limb. I could follow their evolution for about 20 minutes before some clouds decided to develop near the Sun…

150mm F/5 refractor, Quark chromosphere, ASI 174MM.

H-alpha Sun – September 4, 2018

Posted in ASTRO on September 4, 2018 by maxpho

Some H-alpha images of the Sun from a short imaging session. Some nice prominences are observed, but nothing out of the ordinary. We are at the Solar minimum.

150mm F/5 refractor, Quark chromosphere, ASI 174MM. Seeing 6/10.






Lagoon Nebula in H-alpha – August 3, 2018

Posted in ASTRO on September 4, 2018 by maxpho

I’ve tried to get more frames for this object, but I just couldn’t get the time, so I’ve decided to process and post the result of just 1.3 hours of exposure. Poor conditions for this session, light pollution, high humidity, and poor seeing, but some nice details are observed towards the core of the nebula.

Below, an HaRGB version, with RGB filters for the stars, and H-alpha for the nebula.


And a Black-n-White version:

Some nice activity on the Sun today, including one fairly large protuberance.
