Massimo Riccardi Reducer / Flattener 0.75x

[Coco]

Well look what the postman just delivered

As I'm at work and the photo booth's in my office I thought I'd send some images of my new gadget ..

I meant to buy this when I bought my APM early this year but I already had the Tele Vue TRF 2008, Markus Ludes of APM said it would work a treat with the EX428 being

that its got a small chip so I delayed (very true so thanks Markus) , I actually found the little 428 didn't need a flattener at all with the APM 107 combo and the F/6.5 is reasonably fast as it is. Ive now got

another 314L and its similar to the 428 in taht it also doesn't need a flattener so why did I bother? Well I am going to dabble again with OSC and I have my eyes set on a QHY8L

as my next camera, I just loved the OSC work flow although hated the Moon and poor seeing which really punishes Colour CCD's/CMOS's.

I really am looking forward to the f/4.87 speed , its going to come in handy for both the super sensitive ATIK 314 & later the large chipped QHY8 and my 40D which I will be testing it on over the next few weeks..

This image shows the 45mm aperture which will easily cover a DSLR chip...

At over half a kilo its no flyweight

Good piece of kit- can't wait to see the results.

Well I manges 20 x 1 minute's with the Massimo Riccardi Reducer Flattener 0.75x on the APM.. 20 minutes

Just a quick test as the sky was getting foggy and poor (FWHM 2.45 best tonight).. recommended distance from connecting thread to focal plane is between 71,4mm to 81mm so

I set mine at 76mm, as it turns out is not far off, whether the 40D will show more alterations we shall see.

Am very happy with the results so far, the stars a certainly tighter and smaller for an ATIK 314L

I let you be the judges..

Here's an image of the riccardi reducer on the APM, I thought I might as well post this as there has been a few Pm's and emails regarding this setup.. This is also how it sits on a 2.5" feather touch.. On the APM 107 fitted with a 3" focuser it needs to be internally mounted which means the main OTA will need shortening.. APM can do this for you.

My counter weight is a little crude but works a treat - as is the hard wood spacers under the ST80

Hey,

I'm taking advantage of the COVID19 days to make a jump into Astrophotography (I was a visual freak for 5 years now).

I'm eventually aiming to create a rig similar to yours (cheers it looks amazing 🤩).

I have an APM LZOS 100/800 with a 3" ZTA focuser and an M63 riccardi reducer like yours. going to mount on a Skywacher Heq5 .

Is there a chance I will need to send my scope in to APM to have it shortened to reach focus with a rig similar to yours (Mono camera, filter wheel etc)? The focuser on my scope has 180mm of back focus I'm kinda hoping I won't need to go surgical on my OTA.

Clear skies!
