Hello,

 

because we decided to move from suburban village to small town, my imaging days are over frown.gif (at least for now). Because I like to image galaxies and other broadband objects, image processing become more pain than pleasure. I sold all my previous imaging stuff, bought new ASI 533MM camera and Starizona Nexus 0.75x Newtonian reducer. This changed my 12in f4 scope into f3 photon eater. I had problems with collimation but these were resolved by utilizing OCAL electronic collimator and threaded connection of imaging train to focuser. Below are images from first (yet) two nights from my light polluted front yard near Prague, Czech republic.

 

There is a lot of stuff to learn again, because few years ago i used simple Atik Infinity camera and software and it was a joy. Now I have to learn how to deal with gain, offset, SharpCap features etc. But it looks like that camera and reducer are great match to my near astrograph grade scope, and I look forward for next clear nights.

 

Thanks to members of this forum, EAA is for me a great way to stay in touch with my lifetime hobby smile.gif

 

All images were taken at unity gain, no flats, darks applied, saved as seen in Sharpcap. First next thing is to apply flats - evenly illuminated background will help with more convenient image stretch and allow to reveal more contrast and details.

Very nice!  I’m impressed that the corners still look good with your fast setup.  
 

Even if you prefer galaxies, I think you might really enjoy using that setup with an Ha filter for emission nebulas.

Hi Tomas:

 

In addition to the narrow band Ha filter mentioned by Steve, you might really enjoy one of the dual or /tri-band nebula filters made by Optalong. Mine is the L-eNhance but a newer one called the L-eXtreme has had even better reviews.

 

Welcome to EAA!

 

Gary

 

ps: Nice set-up. Is the 12" F4 scope from TS Optiks?

Yes, this is formerly TS UNC scope. I've bought it used, then continously upgraded - new focuser, new spider, new secondary, new primary mirror cell. Only mirror and carbon tube is original.

Welcome!

 

Nice rig!!

 

And you'll have SharpCap figured out and be doing flats in no time. I'll look forward to more of your images.
