Heat Transfer/Reduction System

Optional Heat Reduction System - Benefits Explained

Heat Transfer System: As you may know, digital noise is an ever-present and common problem that must be overcome in the world of astrophotography and any long exposure photography. Spencer's Camera & Photo has developed a heat transfer system that will reduce heat from the imaging sensor while not consuming any battery power. A camera with the heat transfer system installed looks like any other normal camera but with the added benefit of heat transfer technology.

Samples and Comparison Images: Sample Image #1 below is an image taken with a Full Spectrum/Clear converted camera with no heat transfer/cooling system installed. Sample Image #2 is the same exposure, same ISO/sensitivity and the same file size settings but shot with a camera that has our heat transfer/cooling system installed. As you can see the digital noise is lessened by the smaller amount of imaging sensor heat present. The longer the exposure the more digital noise will affect your final image and is dramatically amplified upon post processing and final image editing. Reducing the effects of digital noise in your astrophotography images is vital for the highest quality, most clarity and sharpest images possible. Astrophotography Milky Way

Wow, working with you is just like working with my crew space support group at NASA.  I love working with can-do people.   Thanks for the follow up info here.  It all looks good to me and I know we will put together the best camera produced.  It is a pleasure to work with such dedicated people.  Let me know if you have any issues/questions in dealing with NASA.

Again, it is a pleasure to be working with you.

Dear Clarence,

I got a standard Sony NEX-5 camera and found it’s a single shot colour images quite good. However I was not satisfied with the red colour spectrum in the deep space images and decided to get a conversion done.
It was a pleasure to deal with Spencer’s Camera and my new kit arrived quickly. What a difference it made! The colours are rich and there is less visible noise.
Thanks for the high quality service!

Spencer’s Camera,

I must admit, I was a little skeptical to use your company for the first time for my astroconversion but the quality workmanship has proven to be worth it.  We finally had clear skies for the past week and the conversion has proven to be wonderful.  All my images are clear of dust and the digital noise is noticeably lower than my earlier camera.  I am confident in shooting very long exposures knowing the results will be great.  Astrophotography is a uniquely difficult hobby and having good equipment makes all the difference.  There is nothing more frustrating than equipment limitations especially poor camera quality.  The time and effort you have invested in developing your astroconversion is well worth the results.

Thanks again for the quality work!

I have been shooting my new IR Canon 7D camera for a month that I purchased from you. Everything is just wonderful. I love shooting IR with the ease of no lens filters and no long exposures. The images are crisp and sharp with very nice contrast. Thank you very much for the good job and fast delivery.

Best Regards,
