Testing Nifty Fifty on ASI294 mc pro

Recommended Posts

This was intended as a quick test to see if I could capture anything (at all really) using a good old Canon 50mm 1.8 with an ASI294mc pro, rather than the usual DSLR.

Firstly, I 'locked' the nifty at a usable f4 using my DSLR before releasing it and connecting it to the ASI294.

 

This was connected via the ZWO filter draw, which already contained an Optolong l-eNhance filter. This in turn prompted me to look for a target with some meaningful Ha content. Rather than go with the usual NA and pelican nebs, I decided to point the setup somewhere in the region of the Perseus Double Cluster, in an attempt to capture the Heart & Soul into the bargain.

 

After what seemed like a lifetime trying to manually focus to something half-way decent, I began capturing 60s unguided subs.

Unfortunately, the balcony pillar obstructed the right side of nearly all of the frames so the resultant image has been cropped to remove the annoying blurred obstruction.

 

This crop is 110 x 60s plus darks processed as HOO in APP.

Processed in Astro Pixel Processor and Photoshop CC

Did you upload the image?

Yes, this was intended as a 'warts and all' to identify if it's worth even considering. I would say that the improvement from f1.8 to f4 would warrant stopping down a little bit more. I'm going to try stopping down to f5.6 and spend more time on processing the stars properly as it looks like a nice field of view to have for some targets.

You are getting good images from the balcony. Any vibrations from the floor? Or is it tentative walking about, press the go button and then retire to let it do its own thing?


I generally stand inside the flat before I kick off the main imaging but the balcony structure is pretty stable.

A good result I would say.

 

Funny that your text in the opening post shows up as just off white against a white background. Had to read a quote to see what it said.

 

It was unreadable on my phone so I changed it to white. I’ve fallen victim to ‘theme’ again. Happens every time I paste text in. It’s a total lottery 😩
