M16 contains two famous pillar groups: the Pillars of Creation, made famous by the iconic 1995 HST image, and the other major pillar which looks to me like a dragon head, also recorded in extreme resolution by the HST.


This image is the result of 4.5 hours of imaging on June 10 and 13, 2013 at Sugar Grove Observatory. See some more information at

Prion stars are hypothetical cosmic objects, consisting of preons, supposed elementary particles, which form part of quarks. The density of such an object should be even higher than that of a quark star, and reach 1020 g / cm3. In this case, the mass can not exceed ~ 10-2 solar masses, and the diameter ~ 102 m. According to other sources, the density is at least 1023 g / cm³, the maximum mass reaches ~ 102 M⊕, and the maximum radius is not more than ~ 1 m. Perhaps such objects can be part of the cold dark matter, allowing the paradox of the lack of mass of visible objects to preserve the integrity of galaxies.

The Rosette Nebula (also known as NGC2237) is a large emission nebula in the Monoceros region of the Milky Way Galaxy and is located approximately 5,200 light-years from Earth.


The image is the result of 15 x 900s exposures captured using a QHY8L camera attached to an Altair Wave 115 triplet refractor telescope. The images were captured, calibrated and stacked using Nebulosity 3 and processed using Photoshop CS6.

The photo was taken during astronomical twilight.

The brightest star is Venus.

Thanks to the big enthusiasm lit in me by the incredible feedback on my Orion collage, I'm still at work in developing some recent images acquired during this year astrocamp in August.

This new image is about another "classical" deep sky object, M45 the Pleiades.The image itself is been acquired during 3 nights 9/10/11 August.

It is an LLRGB image of about 90:40:40:40 min. The sky was quite good but with some haze and wet during some nights.

Optic used was a Takahashi Epsilon 210mm f3 on an Astrophysics Match 1 GTO mount. CCD was a QSI 683WSG8 with Astrodon gen II filters guided via a Starlight Xpress Lodestar camera.


Thanks for watching.

Eagle Nebula (M16)

First light with my new ASI1600MM-C.

Also, my first attempt at narrowband. I played around with a bunch of combinations and I liked this one best. There are many things wrong with this one. There was high cloud cover, and I think the backfocus between my coma corrector and camera wasn't quite right because I couldn't collimate accurately. I still love the level of detail.

Last time that i felt like howling was . . . .

caught sight of an interesting moon, no astro equipment so thought i'd use a canon 400 f5.6, nope too small. Added the canon IIx extender. Nope still did not get the frame filled. Switched to a Lumix G3 for the 2x sensor, was getting closer . . . for the math . . . 400 x 2 x 2 = 1600. note the dark mid bottom 1/3 is a power cable running across the moon - just had to say it that way, sorry.

Jantar Mantar, New Delhi



The Yantra Mandir (literally the 'temple of instruments', and often called the Jantar Mantar), is located in the modern city of New Delhi, Delhi. It consists of 13 architectural astronomy instruments, built by Maharaja Jai Singh II of Jaipur, from 1724 onwards, and is one of five built by him, as he was given by Mughal emperor Muhammad Shah the task of revising the calendar and astronomical tables. [1].


The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets. Some of these purposes nowadays would be classified as astrology. " (Wikipedia)
