It's nice to see something taken with a Pentax OTA. There has been a dearth of samples to compare for those of us perennially looking for a better OTA. Drew...
Drew, This is the second Pentax 125 SDP that i've had the pleasure of owning...and honestly "so far" my very BEST ha image captures have been thru the 2...
Last night I switched lenses to the 300mm f/4 pentax smc 6x7 lens. this gives me about 6.19 arc-sec/pixel so I get a pretty big FOV of 5.28 x 3.52 degrees....

This is my first mapped narrow band effort. I used Custom Scientific 4.5nm filters from my light polluted SF Bay Area home north of Berkeley. Camera is an...
thanks for posting Rob You picked an excellent target for your initial foray into tricolor narrowband imaging. I am in castro valley, a bit south of you! I...
Richard, Flats? What flats? I didn't use any. Seriously, I'm all ears, so what specifically in my image would flats improve? I've been admiring your images...
if you really didn't use flats then i recommend using them you will never get the colors right unless you do do you know how to shoot flats? the flats do...

Richard I'm familiar with flats though don't always use them. I generally do twilight flats using a Maxim add-in. I'll shoot a set for each filter (HA, SII,...

Way to go Richard -- nice result ! This version has some great color, but the image seems to be out of focus, or perhaps some other issue. Any ideas what is...
