First light for my Optolong L-eXtreme. It is similar to the L-eNhance but with narrower passbands and no H-beta.

 

This was over two nights.   159x240s at 100 gain and 0 deg C.

 

The star field is so dense here, this was my first attempt at removing the stars with Starnet and then putting them back in at the end. I also used Jon Rista's awesome TGV/MMT noise procedure.

 

C&C welcome. Thanks for looking!

This is a nice image mewmartigan.  Good clean data, great guiding, details, colors and processing.

Thanks Jim! i was really happy with this one.

 

I do like using NINA. I used to use APT and loved it. I switched to NINA for the autofocus routines when I got a ZWO EAF. I like the interface, the options and the speed. Could it do more? sure. Does it do enough for me and do it well? for sure.

 

I believe 1.10 is about to leave beta in the next few days and they are going to work on sequences for 1.11. I am excited to see where it goes.

Hi Mike,

 

Yeah, I am a OSC guy and these newer dual band filters are nice. I had an L-eNhance and this one is just a bit better while still being well below Triad prices. Only one image so far but I am happy with it.

I own the L-eNhance filter. Wondering if it is worth buying the Extreme?

Its my understanding that with the L-eXtreme you do not get Hb - Blue.  IMHO - No.

Yeah, h beta gets filtered out. I believe both Ha and OIII are 7nm passbands. Ha on the eNhance was 10nm and of course the OIII was wide enough to include Hb.

 

I sold my L-eNhance so that offset the cost by a good bit.

I think the main difference is the narrower bandpass. 7 nm for both. This was the reason for me, why I have choosen the Extreme. I hope I can go, at least for H-alpha, when the moon is up.

Awesome shot. I’m gonna have to research that filter. Thought about getting a OSC for targets that I don’t really want to go through the LRGB process
