Interesting comment about a reflection – can you provide more detail? Thanks - Barry Dr. Barry Megdal President Shb Instruments, Inc. 19215 Parthenia St. Suite

afaik you have to use PEMPro-- Brian Brian Valente portfolio brianvalentephotography.com

Can I generate a PEC curve using TheSKyX for the AP1100GTO or do I have to use PEMPRO? Thanks, Khushrow

Small refractors and the small pixel CMOS cameras = a lot of fun. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin -

Barry looks like the image has an internal reflection of the CCD Chip Cheers Mike

I guess I'm not used to such tiny pixels ;^)) Rolando

Very nice detail in the galaxy's core. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin - https://www.astrobin.com/users/deanjacobsen/

Thanks for taking a look Roland and Terri. Roland, it is a single frame. The detector on the ASI1600MM-C is the same size as your QSI 683 -> 4/3". The vertical has been cropped down a little to make

Without... 😆 Pete

Dean, that's a gorgeous shot, wow! The last time I took the crescent was back with a T3i canon on my ES102, needless to say, I didn't capture the fine details that you have captured here. Terri Terri

With or without a miniature umbrella? Rolando

 Simply marvelous. Roland in Hawaii... “Oh Bartender! I’ll have a M100 please! You know... use an AP175 with a QSI 683 wsg-8 served on an AP1600AE gently stirred... NOT SHAKEN!” 🙃 Pete

Great image. Is that a single or mosaic? Rolando

Here is a link to my first ever unguided image using the Mach2 and APCC/APPM. It is only at 318mm focal length but I guess you have to start somewhere: https://www.astrobin.com/full/01gevt/0/ --

Thanks for the tips Terri. I am slowly getting things figured out... one piece at a time. I got point mapping and tracking rate correction for unguided imaging working last night. -- Dean

Rolando, thank you for the update. There's been a couple of times now where I just wanted to roll the scope out during the day to use it for solar viewing, but didn't because i didn't want to get

Just posted another image taken in Hawaii with 1600AE mount and keypad modeling. 300 sec x 34 frames https://www.astrobin.com/full/tjqtnq/0/

OK, got it. BTW, did my first APPM mapping run last night and activated tracking rate correction for the first time with the Mach2. (Third use of the mount under the stars. ) Got a series of 56 x

APPM works differently - it does not use bright stars, just star fields. You need dark skies for that to do plate solves. In my keypad routine you send the mount to known stars using a planetarium

We are working on the instruction manual as I type. Without this it may e difficult to operate all the new features. I'm as anxious as you are to get this part of the project done. You will be asked
