Did the previous 2 R5's exhibit the same hot pixel issue?

Not for a 2 minute exposure no.

Dark frames are normally used to average out the noise in a long exposure astro image so the signal to noise ratio is greater. Bias frames are for reducing fixed-pattern noise. Flat frames are for correcting uneven field illumination and vignetting.

My thoughts after you've had 3 duffers? Sell it quick once repaired and get another model or make of camera. My EM1X has taken loads of long exposures (up to 5 minutes on a star tracker) and very rarely do I get any hot pixels at all.

Pope Shield.

I used that for a while but the V350 will be better as it's less tall than the 685 so will shine more light on the subject. I picked up a Nissin i40 for M4/3 from CEX for £38 and it's brilliant for macro.

Not really Mat. I was advised that the lenses would need to be repaired and was given a quote for the said repair. Nothing was mentioned about a downgrade to the offered price. Make of that what you will but to me it appeared to be a money making exercise. Instead of "changing the process"...

Thanks Mat, To help you track it down here's what I was emailed: "Quotation Number: 50247244 Thank you very much for sending in your used equipment for part-exchange. We would like to speak to you regarding the item(s) you have sent in but have been unable to reach you by phone. Please...

Hi Matt, On 2 occasions now I have sent lenses into Wex for trade in, only to be told a couple of them have moisture inside the rear element and needing repair. Upon asking for the lenses to be returned no moisture to be found. Both of these occasions were in the winter and the only thing I...

Everywhere does it. If you don't like it don't use the internet at all and sell your smartphone. There's no getting around it.

Never took one I'm afraid. I think the tank stirrer came into play but the memories are fading.

When I did my developing in the 90's I'd not heard of a salad spinner but I did make an attachment to allow me to use an electric drill to "spin" the Dev reel. Worked ok for me. Just don't make it too fast.

Olympus OM2n. Superb camera and the Zuiko lenses are also brilliant.
