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.

Pretty good for a point and shoot camera and a great service from http://nova.astrometry.net.

I just built an astro camera tracker with bits costing around £10 and tried it out with my Canon SX230HS. It seemed to track very well and here is a shot of Orion made up of 35 exposures of 150 seconds stacked together in DSS and processed in StarTools.

M42 by Canon SX530HS

Another shot taken with my £95 SX530HS. Software = CHDK, Astrokam, ASPS, PHD2, DSS, StarTools and Paint.Net.

I am a member of the Powershotters group who asked for some details on how I processed this image. Here is a light image:

Original light image. 180sec, 1600ISO, full aperture, 50x optical zoom.

and here is a dark image

The 48 light and 15 dark images were stacked in Deep Sky Stacker along with 25 flats and 15 offsets to produce the FITS image below. This was then processed in StarTools to give the final result above.

Here is a shot I took with my SX530HS PowerShot at maximum optical zoom. Captured in CHDK AstroKam, guided by PHD2, stacked in Deep Sky Stacker and processed in StarTools and Paint.NET.

Not bad for a second hand camera with no telescope?

M31 with Canon SX530HS

Here is my first attempt at deep sky with my new (second-hand) Canon SX530HS compact camera. I shot this with a beta version of AstroKam that I hope to release soon. I only used about a third of the optical zoom range so there is plenty of scope (pun) to chase smaller targets.

Still messing with settings for it but I think it compares well with a similar shot I took with my Canon 1100D below.

I have been working on a new app that will automatically take astro images overnight and below are some early results. All taken with a Canon 1100D and Sigma 70-300mm lens, stacked in Deep Sky Stacker and processed in StarTools.

AstroTour interfaces with PHD2 autoguider (including dithering), All Sky Plate Solver for accurate targeting and digiCamControl for capture. digiCamControl allows a wide range of Canon and Nikon DSLRs to be controlled as well as some Sony and other cameras.

I just treated myself to a second hand Sigma 70-300mm f/4-5.6 APO Macro DG zoom lens for my Canon 1100D and this was my first shot.
