September APSIG Meeting

Hey APSIG gang!

Please join us at the Timberglen Library Tuesday, September 2nd from 6-8pm for our monthly APSIG meeting.

Last month I offered to discuss one of the topics listed below. It was the group consensus that the topic at that meeting should be "Long Focal Length Imaging with a 12" LX200GPS". The remaining topics were covered at meetings last year. I would offer to re-visit one of these topics this month. We can decide on one of these topics at the meeting or select another way to spend our time together. 

Planetary Imaging and Processing
Exoplanet Light Curve observing
Long Focal Length Imaging with a 12" LX200GPS

Don't forget your images for show-n-tell!

See you there!

August APSIG Meeting

Hey APSIG gang!

Please join us at the Timberglen Library Tuesday, August 5th from 6-8pm for our monthly APSIG meeting.

This month we will have a smorgasbord of topics to select from. We can spend time on one, two or three topics depending on the interest of the group. The topics include two topics discussed last year and one with new material. The topics are:

Planetary Imaging and Processing
Exoplanet Light Curve observing
Long Focal Length Imaging with a 12" LX200GPS

The Long FL imaging topic will give an account of the modifications/adjustments and equipment that I have found useful to be able to make long exposure images with a 12" LX200GPS at 3000 mm FL.

See you there!

July APSIG Meeting

Hey APSIG gang!

Please join us at the Timberglen Library Tuesday, July 1st from 6-8pm for our monthly APSIG meeting.

Phil Easton suggested that we have an equipment/hardware show-and-tell theme meeting with special emphasis on Do-It-Yourself AP projects. So, lets have that meeting next week. APSIG members are asked to bring one or two pieces of equipment that they find useful and believe that other APSIG members might find useful. We can either take turns describing the equipment and answering questions or do it all in parallel. When you decide the equipment you plan to bring, please post a message on this forum so that other APSIG members will know what they can expect to see.

Don't forget your images for show-n-tell!

See you there!

June APSIG Meeting

Hey APSIG Gang!

Please join us at the Timberglen Library Tuesday, June 3rd  from 6-8pm for our monthly APSIG meeting. This month Phillip Easton will discuss auto guiding.

Guide your way to happy round stars!

When imaging we all want to see nice tight, round stars.  One of the best ways to accomplish this is with auto guiding.  However, at times auto guiding can be a frustrating and problematic.  This presentation will cover methods for successful auto guiding to help you get them most out of your system.  First the focus will be on different types of hardware and the various attributes of each that contribute to an optimal setup.  Both off-axis guiders and separate guide scopes will be compared to help you decide the best configuration for your system.  Next the talk will highlight some of the free software used for auto guiding with a focus on PHD2.  We will do a walk through of the new features and discuss how to configure the settings to maximize results.  Through-out the talk we will present tips, discuss what good guiding looks like and  troubleshooting to help you get the most out of auto guiding during your imaging sessions.

Don't forget your images for show-n-tell!

March APSIG Meeting

Hey APSIG gang!

Please join us at the Timberglen Library Tuesday, March 4th from 6-8pm for our monthly APSIG meeting.

This month Frank Castanho will be our speaker. Below is his description of topics he plans to cover.

CCDStack is a program designed specifically for image calibration ,

It has some nice features like
Data Rejection
DDP - Digital Development Processing,
De-convolution.
Automatic Image Registration

Data rejection features are useful for removing star blooms ,satellite trails, hot and cold pixels etc , it lets you keep frames that would normally be discarded.

DDP is useful for evaluating the image content by automatically doing automatic curves or dynamic range compression, useful for evaluating images before fully processed

De-convolution is useful for sharpening image features and reducing star size.

I plan on giving a brief power point presentation, followed by a demo of processing an image in CCDStack, and if time is available showing some video excepts from Adam Blocks CCDStack tutorial

Don't forget to bring your raw image data to pass to Dave Raphael for the image data quality analysis presentation.

Don't forget your images for show-n-tell!

I will be out of town for this meeting and David Pearson will coordinate the meeting.

March 4th. is voting day. There will be voting at the Library. I have contacted the Library an they have said that the voting will take place in the classroom across the hall from where our meeting normally takes place. Our meeting location is unchanged.
