    IC 4605

    This nebula surrounds star 22 Scorpii and is part of the colorful Rho Ophiuchi Complex. At magnitude 4.8 the star can be seen near Antares under a dark sky. However, both this nebula and the other nearby features require long exposures to reveal the true nature of what is in this part of the sky.




    Some sources indicate this star does not release enough energy to ionize the surrounding gas and make it glow red- and so the nebula is bluish due to the scattered light from dust. However, this deep image hints that there exists some extremely faint ionization (red) near the star. This nebula is around 400 light years away.

  • Astrophotography with Adam Block

    Mt. Lemmon SkyCenter’s SkyNights: Astrophotography program is a unique and awe-inspiring opportunity to peer beyond the blue horizons of our southwestern skies and explore the astronomical wonders of the Universe. We’ll not only be  looking through the telescope but also capture the views using a CCD camera.

    Renown astrophotographer, Adam Block, will take you through the process of how he creates these amazing images that have earned him worldwide recognition. During this six hour program you will navigate the night sky with binoculars and skycharts then gaze at spectacular planets, galaxies,  and nebulae with our 32-inch Schulman Telescope. This telescope is the largest dedicated public observing telescope in Arizona. You will partake in the process of creating images that you have just viewed that will subsequently be made available to you.
