Disappointing book with questionable advice in places...
on 18 January 2014
This book promises to provide a basic overview of deep sky astrophotography.
I found it very disappointing.
The author is a photographer who attempts to provide an introduction to long exposure astro-imaging "written from the point of view of a beginner". That I suppose he does but I found the text to be unconvincing in places and generally not terribly authoritative. For instance, statements like "Honestly, I don't know what its weight rating really is" and "Takahashi and Losmandy are both top tier mounts that I know very little about" and "I have not been able to see one of these yet but from the images it looks..." don't inspire confidence. My personal favourite is the opening of the "Shooting mono to get colour section" which begins "I should probably mention that as of right now I do not have and have never used a mono camera" which makes me wonder why the author feels qualified to write about them!
The author's assertions are also questionable in places - for instance many would disagree with him that hypertuning a mount doesn't increase load capacity and suggesting that moving an OTA from a Dobsonian mounting to a GEM is not a good idea because "the stresses could be too much and it could literally fall apart" seems highly suspect, at least for the Dobsonians that I've seen. Certainly the author is incorrect to suggest that levelling the tripod is essential for GEM mounts.
Other parts of the book - like the section on stacking using Deep Sky Stacker (DSS) - might be useful for some, but I found in this instance that the tutorials and help files available from DSS are more detailed and so the explanation in this book adds little.
Overall a disappointment for me, I'm afraid.
