I have just bought a Celestron 18771-CGL power tank to allow me to get out to the dark skies of the South Downs with my Nexstar 8SE. This is a great bit of kit because it's so light and portable and powers the scope for hours no problem. However, I've also been thinking about getting a dew heater and the only downside of the power tank is it's lack of a second 12v output. I was looking on the First Light Optics website and they sell a DC splitter cable to allow two devices to be powered from a single output. I'm not an electrician obviously, but logical tells me if the dew heater controller is also a 12v device there should be no problem running both the scope and the heater at the same time other than draining the battery faster. Is anyone using a splitter cable in this way? Or can anyone confirm my logic is flawed?
Sharing with you my best images of Jupiter and Saturn for this year.
I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season.
Not my best images of the gas giants ever but ok IMO.
I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece.
Captured at f33. Images consist of the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos.
On the 12th August, between 18:34 and 19:21 we had a occultation of Saturn by the moon.
Of course I couldn't miss out of such a event so I took the day of work and setup my gear so that I could simultaneously capture the event as well as observe it.
I had the SCT recording with the 618C while observing it in the dob... literally at high power it looked like a Saturn rise... massive lunar horizon filling the field of view with a big Saturn rising from under it, literally animated and visible slowly moving up... Looked amazing in the eyepiece...
Photos or videos don't even come close to how good that looks live in the ep.
I had my eye on the eyepiece in the 14" Skywatcher during the occultation and recorded the start and finish times as soon as I noticed them:
Occultation Start 18:35.51 AEST
Reappearance Start: 19:19.37 AEST
Occultation Finish: 19:21.20 AEST
I stuffed up the first part video, the covering of Saturn because I still had iCap set to capturing a maximum of 5000 frames left from my planetary imaging, so at 25fps I barely got a 3.5 minute video that stopped just before the actual occultation started... yes I was kicking my self... but at least I watched it... I wasn't going to do the same mistake on the re appearance on the other side...
Sharing with you my photos and the video of the event... video is sped up to 400%.
