I definitely did not expect clear weather this morning. Forecast called for clouds and possible rain. It was clear with fog developing in the valley below me. Temps in the low 60's, high humidity, air was still, and the sky looked beautiful.

 

I captured this series of images of Europa and it's shadow transiting the face of Jupiter. 

 

No other processing was done other than stacking in Autostakkert and wavelets in Registax. So, it looks a little uneven from capture to capture.

 

Jupiter's elevation was 27-28 degrees above the horizon.

 

I took some additional images of Saturn and Mars that I will post separately.

 

Scope: Questar 3.5

Camera: ZWO 178MC with Questar focal reducer plugged into axial port

Mount: Davis & Sanford lightweight tripod

 

This should look better if you open the image. The preview image always looks compressed.

 

What a bonus this morning!

Finally the sunrise...with even more fog coming in. It's almost a wall of white right now. Rolled up here quick.

 

6:26 AM update...You can't see any of the hills at all anymore. It's completely white out there now. Fog right up to the deck. Amazing.

Great capture Terry!  Amazes me what Q 3.5's can resolve!  Also, always nice to have a buddy keeping watch.

Thanks again everybody, I sincerely mean that!

 

One more re-do. I have so much glare in this room and on the laptop...I hope this came out ok. 

 

Slightly enlarged version, plus original scale attached.

Wow, these last two re-do's are incredible... bow.gif waytogo.gif

 

I have an ETX-90 and a ZWO ASI178MC camera but I don't think I could come close to that, unless my ETX-90 thinks it's a "Questar 3.5 want to be" scope. lol.gif

 

Thanks for posting, Dan smile.gif

Thanks Dan! At first I wasn't so sure about the re-do, but I like it now. I'm going to look at some of my prior images to see if I can improve them too.

 

Hey those ETX's have really good glass in my opinion. A couple of months ago I bought a Meade DSX-125 OTA (same as ETX, but silver/grey tube). Amazing optics in that thing! The only thing I'm not a fan of is the finder scope. Otherwise I really like it!

Agreed the ETX is quite capable! Although most reviews conclude the Q reveals a slightly brighter image and resolves well all the way to the edge of the field.

 

I solved the finder problem by replacing the straight-through 8x21 with a right-angle 8x25 finder on all my ETXs; it's been a neck-saver!

Thanks! At first I thought I over-processed it. But it's grown on me. Thanks again!

Great post Terry, with terrific images!  I was also up all night with my Questar and will share momentarily.  We're in very different settings but it's cool that we have this way to share the stuff we do with our venerable Questar scopes.  I'm grateful too for all the things I've learned from your progress with Questar imaging over the past few years.

Regards, Mauri

Thank you Mauri! I think you are probably taking more care in your approach to imaging. It's certainly more meticulous and thought out. And it shows in your images! I'm more or less expirementing as I go along and sometimes it works out! I'm definitely enjoying the adventure of it all. I hope to try some deep sky imaging with the Q soon (with Questar focal reducer), and also give the Q700 f/8 another try. My C-6 at f/6.3 does very well in that regard, while still keeping the setup relatively small and compact. But the Q beckons and I like the challenge! 

 

Good luck with your imaging, and thanks again!
