Milky way between the star Sadr (upper left) and the dumbbell nebula (lower right) and rather faint the cirrus nebula (lower left).

After months of bad weather and no imaging finally got out last night. NGC7000 in h-alpha. Pentax k5 ISO400 7x900" exposures. Orion refractor and h-alpha filter.

seti_v2 that is a nice shot. Is your K5 modified to be monochrome? Also which h-alpha did you use? I've been wondering about attempting some Ha stuff with my K5IIs, even though my K5IIs is not modified and I know that would effect exposure times.

My Pentax k5 has a full spectrum mod (essentially just the hotmirror removed) done by Kolari Vision. I use an Omega Optical 7nm H-alpha filter. Since only the red channel picks up h-alpha I just extract and process the red channel as a monochromatic image. DSS for stacking, then FITS Liberator to do initial stretch and red channel extraction.

Hope that helps!

Question for the K5 users. It's probably in this thread somewhere, but not sure exactly what to search. So the new K3ii can do the sensor shift to keep the stars sharp. Can this be done with the K5iis with the optional GPS unit, or not? Thanks.

Pretty sure it can. That's the whole point behind the Pentax GPS module.

Yes it can. I have the K5 and I use the O-GPS1 to take shots up to 5 minutes long. So the K5IIs does this as well.

The K3II just has the GPS Built in so you do not have to buy the O-GPS1 unit.

@seti_v2. It looks very well. Just this night I have made the difference between your pictures and another one taken through a 3.5nm Baader filter, with a QHY9 camera, and yours is OK. Keep the good work.

Baader reinforced 3,5 nm H-Alfa

Just scroll down for the picture.

Got Oiii data added now. NGC7000 in bicolor.



I wish I had the money for 3.5nm filters and dedicated qhy ccd. I don't think my achro set up, cheap filters, and Pentax K5 are doing too bad!

Not "bad" at all. I wish that I could take photographs like that.

I have those narrow band filters for my telescope. I'm wondering if I put them onto an eyepiece and took the photograph through the eyepiece with the filter on the eyepiece if that would work? Has anyone out there done eyepiece projection photography with a DSLR and a Schmidt Cassegrain telescope?

Your set up is doing very well. I could say surprisingly well.
