Peter Shah posted a topic in Deep Space Objects (DSOs),This is another version of NGC281 the Pacman Nebula in Cassiopeia. Going over all my old data to produce a combination of narrow band and RGB. Exposure time was 3 hours in each RGB and 7 and a half hours in H-alpha 1 hour 20mins in both OIII and SII. Total exposure time was 19 hours 10 mins. Imaged with my AG12 Newtonian and H35 camera by Starlight Xpress and My AG8 and H16 for the narrow band data.
Quite a complex process in Photoshop first combining the RGB as doing the normal curve stretches. Adding a separate layer in the Ha to get a real nice deep emission across the field. Then processing the S2, Ha and O3 and giving a soft layered blend to accentuate the core detail. Image data acquired with Maxim dl and CCD Autopilot.
Thanks for looking
Tweedledee posted a topic in General Astronomy Discussion,Get your scopes ready. Last chance to see it for 161 years! The transit will be visible for nearly 10 hours though!
On Thursday 12th July 2018 the earth and moon transit the sun - as seen from Pluto. 😉
With Pluto's orbital period and inclination, I thought this would be a much rarer event than it actually is.
Some interesting info in this article...
Graham posted a topic in Solar,After seeing Steve's brilliant images I just could not let another day go by without doing some Solar.
I spent the morning fitting the antiquated motor drive back onto the new scope and trying to get my head around the wiring.
Eventually got it sorted with the only casualty being my power supply which decided it could not handle the load and went pop.
Back up twin power supplies installed and I was off.
I must say for a DC motor drive it is really pretty good.
Having said that I still cannot wait to get the stepper motor drive up and running.
It took a while adjusting the motor speed to get it tracking correctly but I got there in the end.
I was fighting a fair amount of haze and high cloud but for a first light with the new scope I am very pleased with the result.
