Problems with my Celestron CG-5 Mount Power Port

|Equipment|1 Comment

Problems with Celestron CG-5 Mount Up until this point, my Celestron CG-5 mount has been very good to me. Despite what I have heard, it has been a quality mount, capable of 5+ minute exposures, no problem (with autoguiding).  Recently though, the power has been cutting in and out.  Last Friday night, under clear, dark, moonless skies at the CCCA, I was forced to head home. Devastating!  The frustrating part, is not knowing whether the issue is the power switch, the jack, or the entire power board itself.  The only thing I know for sure is that it is not the ac adapter,…

Frustrations with PHD Guiding

|Equipment|0 Comments

M81 and M82 Update: I've learned a great deal about autoguiding with PHDGuiding (Now PHD2 Guiding) since this post was first published. For an updated perspective, please read: Autoguiding a Telescope for Deep-Sky Imaging (PHD2 Guiding) I had a heck of a night this Friday at my Astronomy Clubs observatory.  The skies were clear for the first time in weeks, and I was excited to shoot Orion before it gets too low in the sky until next year.  Everything seemed to be going great until it was time to calibrate PHD guiding.  Even though my mount was polar aligned perfectly (I did it seve…

M78 Project – Done!

M78 - Reflection Nebula in Orion I am finally done my "winter project" of M78 in the constellation Orion. The winter weather in the Niagara Region doesn't bode to well for astrophotographers as the clear nights are slim to none. Last night, however, I was able to squeeze in another 1.5 hours of shooting on this beautiful subject. I am satisfied with my results, and look forward to moving on to my next project, The Orion Nebula:) Thanks for looking! 72 frames 4 and 4.5 minute exposures 5 hours 30 minutes total exposure Stacked with darks ES ED80 Triplet Apo ASCG-5 GT Orion M…

Astrophotography Processing Graphic

|Tutorials|3 Comments

The following graphic provides an extremely basic break down of the steps that take place from a stacked image to a completed image. In reality, there are about 50 steps (or more) involved when processing a deep-sky astrophotography image such as this. You can click on the image for a larger view.  Basic Processing of an Astro-Photo I created a graphic showing the basic steps needed to turn a raw stack of images (light frames) into a final image. The image is of the incredible Lagoon Nebula in Sagittarius.  This was from data collected in July at the CCCA Observatory in Wel…

M78 – Reflection Nebula

|Nebulae|0 Comments

Here is my image of the M78 Reflection Nebula in Orion. The image below is a stack of multiple exposures combined over three nights, spanning three months! I captured this image using my stock Canon EOS Rebel XSi digital camera and my 80mm triplet apochromatic refractor telescope.  M78 - A Reflection Nebula in Orion  The total time is just under 3 hours with 49 light frames in total. About 1.5 hours of this combined image was captured under dark skies at the CCCA.  Once I get some more time in there (hopefully this Friday), I will ditch the light-pollut…
