M87 was not on my list of targets, but all this hype about its black hole made me curious. So, I pointed my 102mm APO at it, and here it is:

Thanks! I like my little 102. I am surprized how much it can see from my red/white LP area.

Completely amazing.

 

Was the SV FF/FR that you used the SFFR102-2 one? I've been wondering how well that one would pair with my ES 102CF.

Thank you!

Yes, it was SFFR102-2. I am not sure if what I am doing is correct: I just insert it into the 2.5 in focuser and fix in place with compression screws. Flats show that it is slightly off axis. I am still looking for a threaded adaptor for better connection. Not quite sure which size/model will fit.

Geez, so I just tried, was able to get 39x180sec, stacked, looked terrible.

Kinda dumb attempt fro LA with the moon shining nearby.

I started with 180 sec at gain 16, and the image was burnt out. Then I moved to 30-60 sec at the same gain, and the result was acceptable. I had the moon too, and red/white border area of LP.
