nebula

Crescent in Cygnus from Verona. 1.5 hours exposure.

The bubble nebula in Cassiopea, also known as Caldwell 11.

Two hours H Alpha exposure through a 5" refractor and Starlight express CCD camera.

IC410 in Auriga (taken in November 2012) Emission Nebula. The two streamers look like and are called "Tadpoles" of IC410, a denser, cooler gas and dust believed to be a star birth region. Taken thru AT111EDT using Ha filter, 7x600 sec exposures (4200 secs) combined in Maxim, process CS6.

IC1795 Ha image located in Cassiopeia, the red color comes from Hydrogen photon emissions; also note dark lanes of obscuring dust. The brightest area bottom center is known as NGC896. IC1795 is part of IC1805 the Heart Nebula. Image info: 70R, 60G, 60B x 10 min exposures, color combined in Maxim DL, processed in Maxim and Photoshop CS6. Astro-Tech 111edt, Electronic filter wheel, Starlight Xpress ccd and SX autoguider on CGEM mount. North is right.

Emission Nebula IC1795 is only part of a much larger nebula, IC1805, aka the Heart Nebula, located 7500 ly away in Cassiopeia.

BUBBLE NEBULA: Emission Nebula in Cassiopeia at 7800 ly distance. The bright star at 2 o'clock in the Bubble is an O-type star nearing subernova stage and is the source of the Bubbles shape. You may also note that there is another Bubble which is 2 1/2 times larger and dimmer which stretches downward to the bright star near and to the left of image center. Aquired thru an AstroTech111edt refractor @ f/7, Nautilus Motorized Filter Wheel, Ha filter and SXVR-H9 ccd from Whiting, NJ 10-20-12 15 x 10 min exposures combined in Maxim DL, false color added.

3 1/2 HOURS Elephant Nebula (part of) 40 min RGB each at 10 min exposure, 90 min at 10 min exposures Ha combined in Maxim DL. This week is terrific week for imaging as the temperature is cooling down. Nice clear skies. Taken on two nights, Monday & Tuesday, rested Wednesday, out Thursday today for another night of experiment imaging.

Taken 2-1-12 from my back yard thru my 111EDT using the Starlight Xpress SXVR-H9. Wanted to get two hours imaging in, but the guider started to give me problems after 8 5min images. Of the eight 6 were good due to the guiding. This image of the Crab Nebula is 6-5min images combined in MaximDL and slight process in Photoshop CS4.  Located in the constellaion Taurus M1 was created from a supernova explosion in July 1054 (fireworks anyone?).  It is 6,500 years away and 11 lys across.

Rosette Nebula with Couguar. The nebula is in the constellation Monoceros. This was taken with a CCD camera on Dec 25th 2011. The total exposure through an H-Alpha filter took 1.75 hours.
