Moon Pic - "Curtiss Cross" Again

67champ · #1 24-03-2006, 04:11 AM

While in a rush this morning to get a few pics through my new 150mm Mak-Cass before I had to leave for work, I took this pic of the Curtiss Cross. Still haven't made time yet to properly "test" my new scope...... Early indications are that my 127mm mak is just as good..... I'll point it towards the big planets next chance I get to see if there is more detail or not. I may send the 150mm back...... Anyways here's the "cross on the moon" feature. It's there, can you see it?

Hi dt, I assume collimation isn't an issue?

One thing I read too was that as you go upsize with the Mak Cassegrains the cooling time required can go up drammatically. That is you might get to ambient in 30-45 min with a 5inch, but the 6 inch might require substantially more and this will have a big impact on image quality

cheers,

Hi, collimation is right on, and I let it "cool" over night (over 5 hours) before I started using it.... I may have another pic or two from the curtiss cross, but none are as good as I was hoping for this time.

After multiple "tests" and "checks" I sent my Orion 150mm mak-cass back, and I'm staying with my old Orion 127mm mak-cass for a while longer... I've added some ep's and another camera mount to make life easier on me when I'm taking afocal pictures......I hope to have some real nice pics of the moon in a couple weeks.... stay tuned... :-)
