21:11 – 01:12
Focus on Red was 19,562. I then slewed to M2 and took 30+ RGB frames. I do not need Luminance as it added very little to M15. Position angle for this and M15 was 239.580
Tag: M15
Viewing Report 2nd September 2023
21:32 – 00:58
Using the 12″ in the dome this evening to see if I can quickly grab some frames for M15 the Globular cluster in Pegasus.
I’m capturing 60s exposures due to not wanting to oversaturate the stars. I will attempt to get 30 x 60s for LRGB.
Focus position for Luminance 17,131 and RGB 19,505
I captured all frames with the Moon around 88% waining. Some frames were marred by the noise problem on the camera. I have put a ticket into ZWO to see if we can resolve.

Gingergeek came over this evening with his travel rig to setup and test again before our trip. My travel setup is packed away so instead I will image with the 12″ this evening, the first time since May!
Guiding setup was an issue. I did not need to re-calibrate, however TSX kept guiding on a hot pixel. I realised after a long while this was because there were no bright guide stars in the FOV so used the rotator to find one then everything just worked.
Then had a bug with taking a set of images where the run kept using the blank filter. I added another row in TSX and deleted the original which solved the problem. Cloud came in just after 11pm to shut the dome up.
M15 5 min exposure

RGB on SH2 – 132.
RGB focus 19,098, Temp -25℃ GAIN 139 OFFSET 21 , Rotator angle 256.020
Changed rotator angle to find guide star, must remember to force a calibration within PHD2 straight after so that the guiding works.
@ 00:45 LRGB on M15.
Lum focus 20,098, RGB focus 19,098, Temp -25℃ GAIN 139 OFFSET 21, Rotator angle 139.520
Left the observatory running at 00:52 and went to bed.
Forgot to set the Very Light safety limit so dome did not close when the Sun came up……
Need to do flats!!
