All images below were taken with a modified Digital Rebel through Orion ED80 Refractor with Televue .80X Reducer. The ED80 was mounted on an Orion Atlas EQ-G mount. The EQMOD ASCOM driver was used to drive the mount directly via an EQDIR interface module.

 

Equipment used:

 

Temperatures ranged between 22 and 50 degrees Fahrenheit and skies were clear to partly cloudy. PHD Guiding software was used for autoguiding. The webcam software WcCtrl was used to enable long exposure modes on the Logitech Fusion webcam while autoguiding.


M8 & M20 - Lagoon and Trifid Nebulae:

27 two-minute exposures at ISO 1600 were combined in Images Plus using Adaptive Addition. Full Frame Image reduced in size.

 


M17 - Omega (Swan) Nebula:

26 two-minute exposures at ISO 1600 were combined in Images Plus using Adaptive Addition. Full Frame Image reduced in size.

 

 


M16 - Eagle Nebula:

13 two-minute exposures at ISO 1600 were combined in Images Plus using Adaptive Addition. Full Frame Image reduced in size.

 

 


M4 - Globular Cluster:

Three 25 second exposures at ISO 1600 were combined in Images Plus using Adaptive Addition. Full Frame Image reduced in size. Glare from the star Antares is just off frame at bottom left of center. The globular cluster NGC 6144 is also in the image.


Sun in H-Alpha:

60mm Coronado H-alpha filter was used on Orion ED 80 refractor to take image of surface and flare with Modified Canon Digital Rebel on 5/15:

 

 


Conjuntion of Venus and Moon on 5/19:

Images were cropped for display:

Exposure setting for detail on Moon - ISO 100 & 1/25 second.
