I have Celestron Nexstar 8 SE, alt-az mount. I take pictures and videos with my Huawei P10 smartphone with ocular projection, used 25mm plössl eyepiece. It gives 80x magnification, that's not bad for Messier objects. They can be captured only with one shot. Of course with this one shot comes not so many details, as it does with stacked images. Somehow I would say, these pictures looks like the really look through a telescope, for example a sketch.
I have been imaging using my SkyWatcher Startravel 102mm refractor on a Go-To Synscan alt-az mount and Canon 600D DSLR since just before Christmas 2015. Having since read, "Astrophotography on the Go" by Joseph Ashley I have been inspired to use longer exposures, typically 30 seconds at ISO 1600 and to take more images per object (up to 200 light frames) weather permitting. I use Deep Sky Stacker to collate frames and subsequently process the master image using StarTools. I hope this album of images shows improvement upon my earlier attempts.
Since April 2017 I have been using a SkyWatcher Star Adventurer (SA) mount on an old Celestron heavy duty tripod to image DSO's with my Canon DSLR. At Christmas 2017 I received a modified Canon 700D DSLR and an Astronomik clip-in Ha 12nm filter to complement my UHC filter. I am continually impressed by the accuracy of the little SA mount.
In January of 2018 I began using my old CG-5 Go-To mount to take images and later swapped the original Celestron polar scope for an modern SkyWatcher type which has made polar alignment faster and more accurate.
These are photos of my homebrew motor drives in my Pulsar 2.2 metre observatory. The motors are controlled using the Lesvedome ASCOM driver software. I used stepper motors but most people use basic geared DC motors. The shutter drive is powered by a 26 volt LiFePO4 battery. When the dome is in the parked position, the battery is automatically recharged. The dome drive motor uses power from a mains-driven14 volt 20 amp DC PSU. The shutter drive connects to the main controller via wireless, using XBee modules. The main controller has a safety system built in that performs start-up checks for the dome and shutter latches and shutter battery voltage. It also connects to a Hydreon rain sensor and a cloud gauge and will close the shutter if unsafe conditions are detected.
I am happy to try and answer any questions if anyone would like more information.
I joined in the "Beli Brezi" camp near Ardino, Bulgaria, in July. It is an astronomical camp, attended by many students and scientists from all over the country and abroad. I participated in the Meteor Visual Observation Group. We were supposed to observe DEL, CAS, ANT, CAP, PER, SDA and PAU. But with the rest of the group we noticed a lot of sporadic meteors coming from the constellation Cygnus (Swan). We began our exploration and finally concluded that this could be a new meteor shower. It can't be Kappa-Cygnids because they are in August. And the characteristics of the meteors were not the same as those of Alpha-Cignids. My question is, did anyone watch anything like this between July 22 and August 3? If yes, please contact me!
Images taken over ten years or so - so far! Until 31st October 2019 all the DSOs were taken using an Atik 314L+ camera through various telescopes. Planetary - when added - will have all been take using a ZWO ASI120MC througha Meade LX90-8".
Just before Christmas 2015 I began taking photographs of DSO's using my SkyWatcher Startravel 102mm refractor, alt-az mount and Canon 600D DSLR.
To date all images except the Rosette Nebula have been taken using ten second exposure lengths and at ISO 1600.
Image processing uses Deep Sky Stacker and StarTools software.
