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%.
Saturn Lunar Occultation 12Aug2019.mov
Yesterday the Moon was low in the sky (in Scorpius), but he seeing was good and allowed magnifications up to 257x. Gassendi was the most prominent crater on the terminator. Here's a painting of the scene.
The small Moon image (Stellarium) shows the location of Gassendi.
Thank you for watching.
I have guiding problem with the following guider setup: 9x50 finder + ZWO ASI 120mm mini + PHD2.
The imaging scope is a 6' newtonian + canon dslr on a HEQ5, driven by a laptop via diy EQDIR cable.
When the mount is set up and running correctly, polar aligned and all... I connect the guider camera
and mount with phd2. All nice and easy, I run a calibration, then it starts to guide. All seems ok.
Then I am starting to take pictures. The first seems OK, then the second have the star trails...
I check phd2 and there is a message: the camera (ASI) did not take a picture for "xy" seconds so it is disconnected.
Grrr.... I reconnect try to set up a longer period for "xy" in the settings as mentioned in the message.
And all the same again and again. Whatever I add for connection timeout for the camera, it just reaches that
and disconnect the camera.
PHD + philips toucam has worked for me flowlessly. I changed to PHD2 because I gave myself a birthday present,
the little ZWO camera. (and PHD did not recognize it)
Do you have any idea what can be the problem? I will contact PHD2 help also, but maybe somebody had already
the same problem and figured out how to overcome. I am almost sure I make some dumb mistake in the PHD2
software settings, however I tried to change only what was needed.
9 August was a good night for the Moon, so I studied the region from Ptolemaeus to Arzachel at 231x. Especially Alpertragius stood out, with its oversized central mound. It has been suggested that this is a volcanic feature. Herschel too was quite prominent.
Thanks for watching.
Recently I was given a 4 inch skywatcher Newt for which I made a table mount. I thought I would see what you could do imagining wise using this scope and a mono ASI220.
200 frames at full resolution, stacked in Autostakert, processed in Registax6 and given a final polish in Windows Photo. Conditions far from ideal with thin high cloud.
I guess the previous owner will ask for it back...…..
