I use both depending on which scope I'm using.<br /><br />If I'm using the LX90 I usually have it hooked up to a laptop and use Meade Epoch 2000. Works well if I can't see the object and need to find something real faint.<br /><br />If I'm using the Tak FS128 or the TeleVue TV85 I use (usually) Bright Star Atlas and star hop or use the DSC on the G11. <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>
