Re: NGC 3628 from 200 seconds UC18 + DS10cTEC--Galaxy season is my favorite season.
Great photo.
Any adjusting in between the 10 frames to keep focused and centered...or not necessary??

Using a LeNhance filter to make the M82 jets pop
I finally got a tip on how to make the jets pop on M82.? The LeNhance filter really did the job.

Hi Richard. Thanks for the quick response. I appreciate the time and effort you put in to give me a very detailed step by step of your workflow. It really helps me to get a better understanding of what's necessary for me to move forward. Once again, thank?you for your time?and?efforts, Steve

? Hope this helps. ? Richard ? ? Hi Richard. So:
The AN/SC is attached to an ASCOM driver independent of the of the Eagle4S and NUC also running through the ASCOM driver?
That's how you switch between the two star alignment needed to run the AN/SC and the Eagle and NUC to use the Mallincam software , the camera and MS remote control (after the two star alignment)?
Whose ASCOM driver do you use?
Bear with me, the 'lightbulb over my head' is flickering.

Re: Classic Obsession wood maintenance
Thanks! I¡¯m the original owner of mine, purchased in 2009. In Oregon there was enough ambient humidity but here in Arizona I worry about the wood drying out. I¡¯ll probably just wax it for now

Cocoon Nebula via UC18 from my recliner
Remote observing with my UC18, ServoCAT and Argo Navis using "From Planetarium" mode on the Argo Navis. An Eagle4S mounted on the UC18 runs all the software and allows a distant/remote laptop (on the same home network) to use MS Remote Desktop and control the telescope (slew, focus, change filters, control the camera, store all the camera setting in a database, read the weather station and SQM) from the recliner on the big screen TV.

The FireWorks Galaxy NGC 6946 (UC18 and DS287c)
I have clear skies tonight, but 81% humidity.? Will do post processing tonight and set the UC18 up on the deck tomorrow with lower humidity. Here is the FireWorks Galaxy from last summer and just now post processed with Pixinsight.

Re: UC18 with Mallincam DS287c and some post processing of M100
Mark,
The cool thing about the Mallincam SkyRaider family of cameras is that the back focus is only 17.5mm.? I can achieve focus and still have about 3/4" of focus travel left over.? I did not have to change anything.? Just insert the camera and start my remote dob astrophotography (after 2-star alignment and the focus exercise with the mask).??
?
My UC18 has brackets to secure the truss poles on the VMB and I did design a new set of brackets just in case that were 1" shorter.? But they were not needed so they were never built.? I designed the shorter brackets in eMachineShop.com (free cad).? With an extra set of shorter brackets, you don't have to permanently change the telescope.

Re: UC18 with Mallincam DS287c and some post processing of M100
Richard: Thanks so much.
Second question. I assume you've cut down a set of poles to allow for sufficient infocus. Obviously that will change your focal length, correct? I'm new to imaging (tho I've had cameras for a while) especially to using my Obsession for this. Just looking to get the basics correct so as to not have to re-do things.
