Astrophotography. Bright, Victoria, Australia "Dark Sky"


Just a few shots from "Bright" Victoria.

Bright is a 19th century gold mining town in the Alpine region of Victoria Australia.
Today it focuses on Wine Making, Produce, outdoor activities in the summer and winter.

It's a long way from city lights, so the skies are nice and dark.
Dark Skies mean a lot less post processing, to remove "Light Polution" and better imaging quality in general.

Fujinon 55mm f1.8 M42 Lens Review

I recently bought this Fujinon 55mm f1.8 vintage lens for a great price on ebay, It's hard to resist when the price is right.

This is the non EBC (Electron Beam Coating) version which means it only has, most likely a single coating rather than the eleven that EBC involves. Update: Whatever the coating is my impression is very good, I'm loving this lens.

The front element is set back quite a way from the filter threads which may explain why I haven't experienced any flaring, except at really close angles to the sun.

Having just dismantled and cleaned this lens I can report that it's of all aluminium construction with a plastic name ring and rubber focus grip. During reassembly I set its infinity focus point to where I wanted it, and then we're good to go.

This lens uses a different optical formula than most similar Japanese lenses of the time.
It uses an "Asymmetrical Planar" design more common with "Zeiss Biotar's"


If you want to use this Vintage lens with most M42 adapters you will need to remove a little tab from the aperture ring.


This tab communicates the aperture position to its original host, that being a 35mm film camera. I nipped mine off with a small pair of very fine jewelers side cutters, then cleaned it up with a very fine file. I have many such tools, as I used to do mechanical watch repairs. The adapter will also have to push in the aperture pin on the rear of the lens as it does not have an "Auto - Manual" switch. In my case I fitted a brass bush over the pin while I had the lens in pieces.

  • Aperture:         f1.8 f2.8 f4 f5.6 f8 f11 f16   Full Stops Only. 6 blades.
  • Close Focus:  45cm
  • Filter threads: 49mm
  • Focus Throw: Approx 190 degrees
  • Weight:           206gm


The Focus ring is just about perfect for me, with the dimple pattern and the right dampening you can move it easily with one finger and things just snap into focus, as it were. The aperture ring has just the right resistance, clicks positively but smoothly. Not having "half stops" is something that I like as well, I seem to know which "f" stop I'm on without looking.

Until recently I didn't realise how important the "feel" of a lens is, it makes a big difference, almost giving you that that "warm fuzzy" feeling. 

Like a lot of fast vintage lenses, and I'm being really picky, it's just a little soft at the edges wide open, not a bad thing really and there's a tiny bit of purple fringing in high contrast situations, but from f2.8 on, its really sharp, check the comparison down the page. The colours are nice too.

I'm not sure yet, but I think it's the Bokeh that sets it apart, I have other 55mm fast lenses but so far I like this one the best.

I'll have to take more pictures.

Fujinon XF 35mm f1.4 Lens

 Three days ago I bit the bullet and purchased my first Fujinon XF series lens.
Up until then I had only used adapted vintage Pentax lenses. After much review and forum reading I decided on the 35mm f1.4, it having an equivalent field of view as a 52mm lens in 35mm film format and "fast" at f1.4, I considered it the best choice for general walk around and low light.
It has an aperture ring with 1/3 f stop positions so you can fine tune your aperture. The pictures are stunning.




  • Close Focus:  28cm
  • Iris:                   7 blades
  • Contruction:    8 elements in 6 groups (includes 1 aspherical element)
  • Weight:            187gm

I did a very quick "Coma" test last night in the back yard. It was clear, but of course "light polluted" I can say at f 2.0 there is almost no coma, just a little bit which is fantastic, I would never get that result on a fast Vintage lens. I'm very excited about our next trip to some dark skies.
more to follow.

It turns out the skies around Blairgowrie on the Mornington Peninsular are pretty good for Astrophotography. The following picture is a stack of 15 images aligned and stacked using "Hugin" and "Enfuse" and post-processed using "Gimp" all under "Linux" "Ubuntu". Software Details Here.

Whilst this lens may not have been designed for close up work, you can seen from the following pictures that it does a pretty good job of it.
With a bit of cropping you could be excused for thinking it was a macro lens.
