New Image of  Orion's nebula sent to TCAS from member Steve Smith.

LRGB shot in my backyard in Lakewood Park with the QSI690.   

Combination of 254x30s, 135x120s & 383x300s lights for total of 38.5 hours.

All processing in Pixinsight.

NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as "The White Rose" Cluster or "Caroline's Rose" Cluster because when seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above.

Three new images by Steve Barton.

All images taken with a TPO 12” newt with an ASA 3” reducer/corrector and Starlight Xpress H694C. 600mm guide scope with a 2X barlow and Lodestar guider, PHD2 guide software. Capture software is Nebulosity-4 and processed in PixInSight.

Helix Nebula

50-1min,4-10sec,total time, 50 minutes and 40 seconds.



19-2min,Total time, 38 minutes Lights, darks, flats-bias used in the preprocessing, Nebulosity-4, Dithered guiding And processed the same as the Dumbbell Nebula.


Dumbbell  Nebula

3-3min,8-2min,8-1min,8-30sec,8-17sec,8-7sec,Total time, about 40 minutes. Lights and a bad pixel map. no flats or bias used. Bad pixel map used because I did not dither between images. I was guiding with PHD2 with a 600mm guide scope and 2x barlow. Preprocessed and stacked in Nebulosity-4 and processed in PixInSight.

Below are three images taken by Phil Hillrich, a TCAS member.

M45  The Pleadies

M33 Triangulum Galaxy AKA Pinwheel Galaxy

NGC 281 The Pacman Nebula


Phil uses the following : Mount-Atlas EQ-GOTo,-Astro Tech F4 AT 8IN Imaging Newtonian, Cannon EOS Digital Rebel XT, IR Converted with Baader Astro Conversion Filters installed, Guider-Orion Mini Deluxe Auto Guider Package, PHD Guiding Software, Pictures taken and processed with Maxim DL5





The above photograph was taken by Hans, at KPPSP in early July. The milky way in its grand glory.

Below, Hans also sent us  omega Centauri (a southern hemisphere giant globular that Larry C. could tell us all about). In a telescope is about as large as the moon was at the recent lunar eclipse!  (No this is not another one of those yearly Mars hoax emails!).  In the 18" scopes it looked like a crystal chandelier (I think I heard someone say).
