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.

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

There were several request for an equipment/hardware show-and-tell theme meeting during our recent discussions. 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.

At the start of the meeting there are a few issues left over from last meeting we might revisit to reach closure on.

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 plan to arrive a little early and attempt to calibrate the projector. Anyone interested in helping with this activity is welcome.

See you there!

November Meeting - 11/5/2013

Sequence Generator Pro!
 
Ever wished you could automate your imaging sessions without breaking the bank?  Come learn about Sequence Generator Pro from MainSequence Software.  APSIG member David Pearson will show how he uses it to plan mosaics, integrate guiding, use plate-solving and combine many useful features that maximize photon collection time!
