Re: Communal Night-Sky Photography Thread

Mark that is just superb. The focus is spot on and so the detail is amazing.
What lens did you use?

Re: Communal Night-Sky Photography Thread

Thought I would share this.

It was done by an amateur astrophotographer in a small town in Wiltshire.

If anyone needs convincing to try out astrophotography just watch this.

Re: Communal Night-Sky Photography Thread

I tend to agree about darks. Your image if pretty much noise free as far as I can tell from what you have posted.

Flats, however, do make a big difference if you have any dust bunnies on your...

Re: Communal Night-Sky Photography Thread

Superb capture. Very little noise as well.
Did you also take flats, darks, and bias frames to use in DSS?

Re: Communal Night-Sky Photography Thread

Lovely image John.

You certainly get the best possible results from your Oly and the Star Adventurer mount.
For me, it seems that it ends up being about your local night sky seeing, then your...

Re: Communal Night-Sky Photography Thread

Added RGB last night to NGC4565. Full moon and High cloud made the image worse in the end but thought I would share anyway.

Re: Communal Night-Sky Photography Thread

It's not daft at all.

Tracking is when the mount moves the attached camera or scope at a fixed rate across the sky entirely under its own control, rotating the camera at the same time. Normally...

Re: Communal Night-Sky Photography Thread

One thing to consider when choosing a tracking mount is polar alignment.
The accuracy of polar alignment is a critical aspect of taking long exposure astro pictures. Assuming that you are in the...

Re: Communal Night-Sky Photography Thread

In theory yes, as long as the Oly is fixed to a tracking mount and the mount was being guided.

The sensor size on my ZWO ASI 1600M Astro CMOS camera is very close to M4/3 in size and is also...

Re: Communal Night-Sky Photography Thread

It's actually 3 shots taken hand held using my 300mm plus MC14
ISO 250, f/5.6, 1/250th sec.

I stacked them in PS and sharpened a touch thats it.

The sky was crystal clear for a change.

Amazing how many galaxies are in this area of sky.

Needs a lot more exposure time and my guiding was not good enough.
