The sky was clear but a lot of heat rising from the ground. 3 X 300 seconds for R G B with RC Astrograph Processed with Observation manager 9.12e using Astroart 7 script interface.
This is an easy one as it is an A0 spectral type. Type Ao with SA200 grating Yes, this is the result of a star measurement session. A time series of V filtered measurements of RW Tri at 880LY. From this information you can estimate sizes of objects and rotational period. RW Tri Time Series. I just love this nebular. Star forming area of dust and gas. This is a better image than before Xmas. Two sets of exposures to get the core and the dust areas. Techy bit: 3 x 100sec per RGB and 4 X 130sec L merged with 3X 60sec per RGB and 4 X 60sec Luminance. […] Ok I have taken quite a good image of this tricky nebula. Take a look on the web and look at some of the images. 4 X 400sec per RGB. No darks. (had to manually take out a couple of hot ones) RGB Image of Cacoon Nebula […] Not bad image considering the gusty wind. Just 3 X 300sec per colour OK, I now have the controlPHD.exe and the AA6 script to control PHD2 from Observation manager scripts. Tested and now working on getting the new site up and running. Woodland Observatory – Selsey . Build the top of the observatory first 11ft square brick built. Hope to get operational again in a month!!
Managed to get M33 as it was a clear but very bright night. Finally fixed the problem of round stars on long exposures. 6 X 600sec 8inch RC Astrograph and SXVR-H18 at -20degC Orion – Horsehead nebula |
