My new SV105 camera just turned up from China for £36 including 7 day delivery. Remarkable, considering a lot of UK vendors won’t deliver to Scotland. Worked straight out of the box so hooked it up to my 140Mak and left DSSR running overnight capturing a series of lunar mosaics. The best seeing was just before dawn and you can watch a flyover animation of the resulting mosaic below.
And below is another animation made on the 23rd January 2021:
My astro mount is beside my garage with a PC just inside to control it. I can control the mount and cameras remotely from my home study using Google Remote Desktop – but not my Orion AccuFocus focusers.
I read a forum post (that I can’t now find) which explained how to control the focuser over USB. I adapted it slightly to avoid the need for stripping one end of the focuser cable by adding an RJ10 socket.
I took this with a second hand, grade C Canon A810 camera I got for £12 looking thru the eyepiece of my Nextar 4SE. Capture of 54x 30sec videos done in CHDK-PTP, stacking in AviStack, stitched in MS ICE and polished in Paint.NET.
This was taken with my SX530HS using the CHDK extended video script to capture 200 minutes of video. I then selected all the feeder visits in DMD which produced a 27 minute ShotCut project file. This was slowed to half speed to better show the action and the sound track was cleaned up in Audacity to remove camera and traffic noise. Watch out for the one legged blackbird which we have nursed back to health over the past few months.
These images were taken using my Canon SX530HS with its zoom set to 100x (2400mm EFL). Capture was controlled by CHDK AstroKam and autoguiding by DSSR. Best 500 of 1000 jpegs were cropped in PIPP, stacked in AS3! and wavelets in Registax.
Scotland had a great spell of cloud free weather in Spring 2020 and below are some of my deep sky captures. All were captured on my Canon PowerShot SX530HS superzoom camera using CHDK AstroKam, stacked in Deep Sky Stacker and processed in StarTools. Click an image for full size.
M101 captured with a Canon SX530HS at 50x zoom in CHDK AstroKam. 50x200sec lights at f8 and ISO 1600 with 15 each darks and offsets. Stacked in Deep Sky Stacker, processed in StarTools and polished in Paint.net.
I took a shot of the night sky with my SX530HS and submitted it to nova.astrometry.net for analysis. They returned the result within a few minutes, including a copy of the original image with deep sky object labels superimposed. Below is a detail of that image.
