Picked up a 2nd hand MN190 yesterday and what a scope! Luckily it was a sunny day and I could do all my initial alignments with guidescope etc during the day and was imaging by 23:30.

I see field flatteners being sold in my near future :-)

9 x 15 min H-Alpha

Great shot, great scope.... sleepless nights :grin:

Thanks! This is the best plug and play scope I've had...just spent about 30 min playing with spacers to get focusing right, otherwise dead easy!

I see that on some of your other posts, you emphasize putting the 383l+ on its own USB cable. does this make a massive difference? I run my mount, guidecam and 383L+ to a powered hub, then just a single USB cable to inside. Would you suggest differently?

I had some trouble with noise on my 383L - I wasn't sure what caused it but suspect it was the power cable rather than USB (I was looping on from one 12v supply) but if your subs are nice and clean - as they appear to be from your Pacman - then why worry! All looks good to me!

Like x6gas - I had some (not many) problems with noise running everything through a powered hub. I tried running the 383L+ straight to the PC via its own cable and the random noise disappeared - stayed that way since.

Everything else goes through the hub to the PC.

I now use two Maplin 12v 7amp DC supplies one powers the cameras the other the mount / heaters etc. I just try to keep any cable that sends or pulses power away from signal cables - OTT, probably but for the cost of a couple of cables....

Congrats on the scope, that's very nice for first light. I guide mine with the QHY5 on an OAG for simplicity. Great scopes as long as you've got 'em collimated properly! :smiley:
